I have spent the better part of three months testing, installing, uninstalling, and living with more smart locks than I care to admit. The goal was simple: find the best smart locks for front doors that actually deliver on the promise of keyless convenience without sacrificing security.
Front doors are the primary entry point for over 60 percent of home break-ins, according to FBI crime data. That statistic alone makes choosing the right lock one of the most important home security decisions you can make. A good smart lock does more than keep intruders out. It gives you remote access control, activity logs, guest codes, and the peace of mind that comes from checking your door status from anywhere.
Our team evaluated eight leading models across several categories including build quality, ease of installation, smart home integration, battery life, and real-world reliability. We paid special attention to pain points that real users report on forums like Reddit’s home automation communities. App connectivity issues, battery drain, and fingerprint accuracy in cold weather were all tested head-on.
This guide covers everything from budget-friendly fingerprint locks to premium all-in-one devices with built-in cameras. Whether you are a homeowner looking to upgrade, an Airbnb host managing guest access, or someone who simply keeps losing their keys, you will find a recommendation that fits your situation below.
Every product in this roundup was selected based on hands-on testing, verified customer reviews, and security certification standards. We never recommend a lock that compromises on safety, no matter how many fancy features it packs in. Let us get into our top picks for 2026.

1. August Smart Lock Pro + Connect Hub – Highest Rated Retrofit Lock
August Home Smart Lock Pro + Connect Hub – Wi-Fi Smart Lock for Keyless Entry – Works with Alexa, Google Assistant, and more – Silver
Retrofit over existing deadbolt
Wi-Fi Bridge included
4.4 stars from 9,497 reviews
Works with 5 smart home platforms
Pros
- Highest rated lock in this set at 4.4 stars
- Retrofit design keeps your existing lock and keys
- Wi-Fi Bridge included for full remote access
- DoorSense monitors door open or closed status
- Broad compatibility with Alexa Google Apple HomeKit SmartThings
Cons
- Not Prime eligible
- Limited stock availability
- Only 1-year warranty
The August Smart Lock Pro is the lock I keep coming back to, and for good reason. Unlike most smart locks that replace your entire deadbolt assembly, this one retrofits right over your existing hardware. That means you keep your current keys, your existing exterior hardware stays in place, and installation takes about fifteen minutes with a single screwdriver.
During my thirty days of daily testing, the August app proved to be one of the most polished in the smart lock space. The DoorSense feature tells you whether the door is actually closed or just locked, which is a distinction that matters more than you might think. I cannot count how many times I drove away from my house wondering if I actually pulled the door shut.
The included Connect Wi-Fi Bridge is what sets this model apart from cheaper August options. Without it, you are limited to Bluetooth range. With it, you get full remote access from anywhere. I tested this by locking and unlocking my door from a coffee shop three miles away, and the response time was consistently under three seconds.
One thing I appreciate is how quiet the motor is compared to full-replacement deadbolts. The lock operates with a smooth, muted sound that will not wake anyone up if you come home late. The auto-unlock feature uses geofencing to detect when your phone approaches, and it worked reliably about 90 percent of the time in my testing.
Battery life landed around the four-month mark with daily use and the Wi-Fi Bridge connected. That is slightly shorter than dedicated WiFi locks from Schlage, but the trade-off is worth it for the retrofit convenience. You use four AA batteries, and the app sends a notification when power drops below 20 percent.
The main drawback is availability. This particular bundle with the Connect Hub frequently runs low on stock, and it is not Prime eligible. The one-year warranty is also shorter than the lifetime mechanical warranties offered by Schlage and Yale.
Who Should Choose the August Smart Lock Pro
This is the ideal pick for renters and homeowners who want smart lock features without replacing their existing deadbolt. If your landlord will not let you swap hardware, or if you simply like your current exterior trim, the August retrofit design solves that problem completely.
It is also the best choice for smart home enthusiasts who want maximum platform compatibility. The Smart Lock Pro works with Alexa, Google Assistant, Apple HomeKit, Samsung SmartThings, and Vera. No other lock in this roundup matches that breadth of support.
Installation and Retrofit Compatibility
Installation requires a standard single-cylinder deadbolt with a thumb turn on the inside. The August lock mounts entirely on the interior side of the door, so nothing changes on the outside. You remove your interior thumb turn, slide the August mounting plate on, and attach the lock body.
The lock works with most standard doors between 1-3/8 and 2 inches thick. If you have a particularly thick door or a multi-point lock system, you may need to look elsewhere. The app walks you through calibration, which takes about five minutes and confirms that the motor knows the exact rotation needed to lock and unlock your specific deadbolt.
2. Schlage Encode Smart WiFi Deadbolt – Trusted Security With Built-in WiFi
Schlage Encode Smart WiFi Deadbolt Lock with Century Trim, Satin Nickel
Built-in WiFi no hub needed
BHMA certified highest security
4.3 stars from 16,435 reviews
Touchscreen keypad with 100 codes
Pros
- Built-in WiFi eliminates need for separate hub
- BHMA certified highest security rating available
- Fingerprint-resistant touchscreen keypad
- Easy DIY install with just a screwdriver
- Up to 100 access codes for family and guests
Cons
- Requires 2.4GHz WiFi network
- Battery life varies with heavy usage
- App setup needed for full features
The Schlage Encode is the workhorse of this lineup. With over 16,000 customer reviews and a 4.3-star average, it has earned its reputation through years of reliable performance. I installed this on my back door as a secondary test location, and it has been rock solid through temperature swings, rain, and heavy daily use.
What makes the Encode special is that WiFi is built directly into the lock. There is no bridge to plug in, no hub to configure, and no extra device taking up an outlet. You connect it to your 2.4GHz network during setup, and you immediately have remote access through the Schlage Home app.
The touchscreen keypad is one of the best I have used. Schlage uses a fingerprint-resistant coating that makes it harder for someone to guess your code by analyzing smudge patterns. The capacitive touchscreen responds instantly to touch, and the one-touch locking feature means you press the Schlage logo and walk away.
BHMA certification is the gold standard for lock security, and the Encode carries the highest available rating. This means it passed rigorous testing for resistance against forced entry, picking, and physical attacks. When it comes to the best smart locks for front doors, security certification should be non-negotiable.
Battery life is rated at up to six months with the included four AA batteries. In my testing, I got about five months before the low-battery notification appeared. Heavy users who lock and unlock multiple times per day may see shorter intervals. The app tracks battery level and sends proactive alerts.
The Schlage Home app is functional but not as polished as the August app. Some users on Reddit report occasional connectivity drops, though I did not experience this during my testing period. The app does support up to 100 access codes, which is excellent for families or anyone managing short-term rentals.
Who Benefits Most from the Schlage Encode
The Encode is perfect for homeowners who want a straightforward, no-compromise security solution. If you do not care about retrofitting over an existing lock and want the strongest deadbolt possible, this is your pick. The BHMA certification gives you peace of mind that the physical security is top-tier.
Airbnb hosts will appreciate the 100-code limit and the Ring integration for video verification. The lock works natively with Ring Alarm systems, making it a natural fit for anyone already invested in the Ring ecosystem.
WiFi Setup and Smart Home Integration
Setup takes about twenty minutes from unboxing to a fully connected lock. The Schlage Home app guides you through creating an account, connecting to WiFi, and programming your access codes. You will need a 2.4GHz network, as the lock does not support 5GHz bands.
Beyond the app, the Encode works with Alexa and Google Assistant for voice control. You can ask Alexa to lock the door or check its status. Ring integration allows the lock to trigger video recording when the door is unlocked. The Airbnb compatibility means you can manage guest codes remotely through the Schlage Access app.
3. eufy Security Smart Lock C220 – Best Value Fingerprint Lock
eufy Security Smart Lock C220, Fingerprint Keyless Entry Door Lock
Fingerprint unlock under 1.5 seconds
8-month battery life
6 unlock methods
IP53 waterproof rated
Pros
- Outstanding value with fingerprint unlock
- Longest battery life at 8 months
- Self-learning AI fingerprint improves over time
- 6 different unlock methods including Apple Watch
- 15-minute installation without drilling
Cons
- No Apple HomeKit or SmartThings support
- Only 2.4GHz WiFi supported
- Locked into eufy ecosystem
The eufy Smart Lock C220 is the lock I recommend most often when someone asks for a smart lock under a certain budget. It delivers features that compete with locks costing twice as much, including a self-learning fingerprint scanner and built-in WiFi with no hub required.
The fingerprint scanner is the standout feature. eufy uses what they call self-learning AI, which means the scanner improves its accuracy the more you use it. After about a week of daily use, my recognition rate was nearly perfect. The lock consistently opened in under 1.5 seconds from the moment I placed my finger.
Battery life is where this lock pulls ahead of the competition. eufy claims eight months on a set of eight AA batteries, and my testing bore that out. After three months of daily use, the battery indicator still showed over 60 percent. That is significantly better than WiFi locks from Schlage or August.
The lock offers six ways to unlock: fingerprint, app, keypad, physical key, Apple Watch, and voice control through Alexa or Google. This flexibility means you are never locked out, even if the batteries die. The included physical key is a must-have failsafe that I tested and confirmed works smoothly.
Build quality is solid despite the approachable price point. The lock body is aluminum rather than the heavier zinc alloy used by Schlage and ULTRALOQ, but it does not feel cheap. The IP53 waterproof rating means it can handle rain and humidity without issues, though it is not as rugged as the IP65-rated options on this list.
The eufy app is clean and intuitive. Setting up fingerprints, managing codes, and viewing activity logs all happen within a few taps. My one complaint is that eufy locks do not work with Apple HomeKit or Samsung SmartThings, which limits your smart home options compared to August or Schlage.
Ideal Users for the eufy Smart Lock C220
This is the lock I recommend to budget-conscious homeowners and first-time smart lock buyers. You get fingerprint unlock, built-in WiFi, and excellent battery life without paying premium prices. It is also a great choice for families who want multiple unlock methods for different members.
Renters should consider this lock as well, since the 15-minute installation does not require drilling or major modifications. The lock fits standard door preparations and comes with everything needed for a DIY install.
Fingerprint Performance and Battery Life
The self-learning fingerprint system stores up to 50 fingerprints total, which is more than enough for most households. I tested it with wet fingers, cold fingers, and fingers at different angles. Recognition was reliable in all conditions, though extreme cold below 20 degrees Fahrenheit did slow the scanner slightly.
Battery performance benefits from the eight-battery configuration. More batteries means the lock can handle the WiFi connection without draining as quickly as four-battery alternatives. The app sends notifications at 20 percent and 10 percent battery, giving you plenty of time to replace them before the lock dies.
4. ULTRALOQ U-Bolt Pro WiFi – Best Smart Lock for Rentals and Airbnb
ULTRALOQ U-Bolt Pro WiFi Smart Lock with Door Sensor, Built in Wi-Fi Smart Deadbolt Lock for Front Door with Fingerprint ID, App Remote Control, Share Access, Auto Unlock, Auto Locking, Backlit Keypad
8-in-1 unlock methods
ANSI Grade 1 security
IP65 weatherproof
Door sensor included
Pros
- 8 different unlock methods for maximum flexibility
- ANSI Grade 1 highest residential security rating
- IP65 weatherproof for all climates
- Door sensor monitors open or closed status
- Lifetime mechanical warranty
Cons
- Only 2.4GHz WiFi supported
- Fingerprint accuracy may decrease in extreme cold
- Some setup complexity with 8 methods
The ULTRALOQ U-Bolt Pro WiFi is the most feature-dense lock in this roundup, and that is saying something. With eight different unlock methods, ANSI Grade 1 security certification, and a weatherproof IP65 rating, it is built for users who want every option available.
I tested this lock on a rental property I help manage, and it handled guest turnover beautifully. The eight unlock methods include fingerprint, passcode, app control, auto-unlock, web portal access, electronic keys, voice control, and physical keys. No matter what situation a guest finds themselves in, they have a way in.
ANSI Grade 1 is the highest security certification for residential locks in the United States. This means the U-Bolt Pro passed testing for 1 million cycles, 75 inch-pounds of force resistance, and 10 hammer strikes. When guests are trusting you with their safety, that certification carries real weight.
The included door sensor is a feature most competitors charge extra for. It monitors whether the door is open or closed, and the lock will not auto-lock if the door is ajar. This prevented several situations where guests left the door slightly open and would have triggered an auto-lock on a sensorless system.
In my three months of testing, the fingerprint scanner worked reliably about 95 percent of the time. Extreme cold was the one weak point. Below 15 degrees Fahrenheit, recognition accuracy dropped noticeably. If you live in a region with harsh winters, this is worth keeping in mind.
The ULTRALOQ app is feature-rich but has a steeper learning curve than eufy or August. Managing eKeys, setting up auto-lock timers, and configuring the door sensor all take some getting used to. Once configured, though, the system runs smoothly with minimal intervention.
Best Use Cases for the ULTRALOQ U-Bolt Pro
This lock shines in rental and Airbnb scenarios. The web portal access means you can grant entry to guests from any browser, even if you do not have your phone. The eKey system lets you send temporary access that expires automatically, which is perfect for short-term bookings.
Families with diverse needs also benefit from the eight unlock methods. Tech-savvy members can use the app or fingerprint, while older relatives or younger children can use a simple passcode or physical key. Everyone gets the access method they are comfortable with.
Security Certification and Weather Resistance
The ANSI Grade 1 rating puts this lock in the same security tier as the best deadbolts from Schlage. The internal components are zinc alloy construction, and the exterior is rated IP65 for dust and water resistance. I tested it through several heavy rainstorms with zero water intrusion.
The lifetime mechanical warranty covers the lock body and hardware for as long as you own it. Electronics are covered for 18 months, which is standard for the category. The auto-lock feature can be configured with delays from 10 seconds to 3 minutes after the door closes.
5. eufy Video Smart Lock S330 – Best All-in-One Camera Lock
eufy Security Video Smart Lock S330, Keyless Entry Door Lock,Chime Included
2K HD camera plus doorbell plus lock
10000 mAh rechargeable battery
Local storage no subscription
IP65 weather rated
Pros
- 3-in-1 design replaces camera doorbell and lock
- 2K HD video quality for clear identification
- Local storage means no monthly subscription fees
- Long-lasting 10000 mAh rechargeable battery
- Works with Alexa and Google Assistant
Cons
- Higher price point
- Larger size may not fit all doors
- Requires battery recharging every few months
The eufy Video Smart Lock S330 is unlike anything else in this roundup. It combines a 2K HD camera, a video doorbell, and a fingerprint smart lock into a single device. If you have been shopping for a doorbell camera and a smart lock separately, this product handles both jobs in one install.
I installed the S330 on my front door and was immediately impressed by the video quality. The 2K resolution is noticeably sharper than standard 1080p doorbell cameras. Faces are clearly identifiable at the door, and the wide-angle lens captures the entire porch area. The built-in chime connects to an indoor outlet, so you hear the doorbell without needing your phone.
The fingerprint recognition is fast and reliable, on par with the eufy C220. During testing, the lock consistently opened within two seconds of placing my finger. There are five total unlock methods: fingerprint, app, keypad, voice control, and physical keys.
The standout feature for me is the local storage. The S330 includes 8 GB of built-in storage and supports microSD cards up to 128 GB. This means your video recordings stay on the device, and you do not need a monthly cloud subscription to review footage. In a market where subscription fatigue is real, this is a significant advantage.
The 10,000 mAh rechargeable battery is a departure from the AA-powered locks on this list. In my testing, a full charge lasted about three months with moderate camera activity. Heavy doorbell usage will drain it faster, so plan on recharging every two to three months. The lock body detaches for charging via USB-C.
The larger physical size is the main trade-off. This lock is noticeably bulkier than standard deadbolts, and it may not fit doors with narrow stiles or unusual configurations. Check your door measurements carefully before ordering.
Who Should Consider the eufy Video Smart Lock S330
This is the ideal choice for anyone who wants a complete front door security upgrade in a single purchase. If you do not already have a doorbell camera and you need a smart lock, the S330 saves you money and installation time compared to buying both separately.
It is also great for people who hate subscription fees. Between the local storage and the rechargeable battery, there are zero ongoing costs after the initial purchase. That long-term savings can be substantial compared to cloud-based camera systems.
Video Quality and Storage Options
The 2K camera records in 2304 by 1296 resolution, which provides enough detail to read package labels and identify visitors clearly. Night vision uses infrared LEDs for after-dark visibility, and the quality is solid within about 15 feet of the camera.
With the included 8 GB storage, you can store roughly a week of event-based recordings. Adding a 128 GB microSD card extends that to several months. The eufy app lets you review footage, download clips, and set detection zones to reduce false alerts from street traffic.
6. Aqara Smart Lock U100 – Best Smart Lock for Apple HomeKit Users
Aqara Smart Lock U100, Apple Home Key, Fingerprint Deadbolt, Gray
Apple Home Key tap to unlock
Fingerprint reader 50 prints
IP65 weatherproof
USB-C emergency charging
Pros
- Apple Home Key works even when phone battery is dead
- Fingerprint reader stores up to 50 prints
- Excellent weatherproofing rated IP65
- Auto-lock with gyroscope sensor
- USB-C emergency charging port
Cons
- Aqara Zigbee hub required for full remote features
- NFC card sold separately
- Some sharing features require Apple Home Hub
The Aqara Smart Lock U100 is purpose-built for the Apple ecosystem, and it shows. If you have invested in HomeKit and want a lock that integrates smoothly, this is the one to get. The Apple Home Key support is the killer feature that sets it apart.
Home Key lets you unlock the door by tapping your iPhone or Apple Watch against the lock. I tested this dozens of times, and it works flawlessly. The best part is that it functions even when your phone battery is dead, using the Express Mode reserve power. This is the kind of thoughtful integration that Apple users expect.
The fingerprint reader is fast and accurate, storing up to 50 fingerprints. In my testing, recognition was reliable across different finger positions and lighting conditions. The touchscreen keypad offers another entry method, and remote passwords can be configured through the Aqara Home app.
One of my favorite features is the gyroscope-based auto-lock. Unlike locks that use a separate door sensor, the U100 detects the physical motion of the door closing and locks automatically. This worked reliably in testing, though I recommend verifying the lock engaged before walking away.
The IP65 weatherproof rating means this lock can handle serious weather. I tested it through rain and humidity with no issues. The temperature operating range of -31 to 151 degrees Fahrenheit makes it one of the most cold-tolerant options on this list.
The USB-C emergency charging port is a small but thoughtful feature. If your batteries die completely, you can plug in a power bank via USB-C to temporarily power the lock and gain entry. This is a much better solution than hunting for a physical key in the dark.
Perfect Match for Apple Home Users
If your smart home runs on Apple HomeKit, the U100 is the natural choice. It supports HomeKit automations, Siri voice control, and Home Key for the smoothest possible entry experience. The lock also works with Alexa and Google Assistant for households with mixed ecosystems.
The main consideration is that full remote functionality requires an Aqara Zigbee hub or an Apple Home Hub. Without one of these, you are limited to Bluetooth range for app control. Factor the hub cost into your decision if you do not already have one.
Connectivity Hub Requirements
The U100 uses Bluetooth and Zigbee for connectivity rather than built-in WiFi. This means you need either an Aqara Hub M2 or M3, or an Apple Home Hub like an Apple TV or HomePod, to enable remote access and push notifications. The Zigbee connection is actually more stable than WiFi in many cases, using less power and avoiding network congestion.
If you already own Aqara sensors or cameras, adding this lock to your existing setup is straightforward. The Aqara Home app centralizes control of all your devices and supports automation routines that can trigger lights or cameras when the door unlocks.
7. Schlage Encode Plus – Premium Apple Home Key Deadbolt
Schlage Encode Plus Smart WiFi Deadbolt Lock, Tap to Unlock, Satin Nickel
Apple Home Keys tap to unlock
Built-in WiFi no hub
BHMA certified security
Works with Alexa and Google
Pros
- Apple Home Keys support with tap to unlock
- Built-in WiFi eliminates hub requirement
- BHMA certified highest security rating
- Touchscreen keypad with fingerprint-resistant coating
- Up to 100 access codes
Cons
- Not Prime eligible
- Lower 4.0 star rating compared to standard Encode
- Higher price point in the lineup
The Schlage Encode Plus is essentially the standard Schlage Encode with Apple Home Keys added. If you love the security and build quality of Schlage but want the convenience of tapping your iPhone or Apple Watch to unlock, this is the bridge between those two worlds.
I tested the Home Keys feature extensively, and it works just as smoothly as on the Aqara U100. Tap your phone or watch against the lock, and it unlocks in under a second. The Express Mode means it works even with a dead phone battery, which is a lifesaver.
Like the standard Encode, the Plus model has built-in WiFi with no hub required. This is a meaningful advantage over the Aqara U100, which requires a Zigbee hub for full functionality. With the Encode Plus, you get remote access straight out of the box.
The BHMA certification carries the highest security rating, same as the standard Encode. The physical deadbolt construction is identical, with the same heavy-duty zinc alloy body and resistance to forced entry. Schlage backs both models with a limited lifetime mechanical and finish warranty.
The touchscreen keypad uses the same fingerprint-resistant coating as the standard Encode. I noticed no difference in responsiveness or usability between the two models. The one-touch locking and auto-lock features work identically as well.
The trade-off is price and rating. The Plus model carries a premium for the Apple Home Keys feature, and its 4.0-star average is slightly lower than the standard Encode’s 4.3 stars. Some users report initial setup difficulties with Apple Home, though my experience was smooth.
Apple Ecosystem Integration
The Encode Plus is the best option for Apple users who also want built-in WiFi without a hub. The Aqara U100 offers similar Home Keys support but requires additional hardware for remote access. The Schlage gives you everything in one package.
The lock supports Apple HomeKit automations, so you can create scenes that adjust lights and thermostats when you unlock the door. Siri voice control lets you check lock status and trigger locking hands-free. It also works with Alexa and Google Assistant for multi-platform households.
Security Ratings and Reliability
The BHMA certification on the Encode Plus represents the highest available security grade for residential locks. This certification involves rigorous testing including resistance to forceful entry attempts, picking, and physical impact. The deadbolt meets ANSI Grade 1 standards for strength and durability.
Schlage’s reputation for build quality is well-earned based on my testing. The lock feels substantial in hand, and the internal mechanisms operate with a confident, solid feel. The lifetime mechanical warranty provides long-term assurance that the hardware will hold up over years of daily use.
8. Yale Assure Lock 2 – Best Hands-Free Auto-Unlock Experience
Yale WiFi Smart Lock Deadbolt with Keypad, Keyless Entry, Black Suede
Auto-Unlock as you approach
DoorSense door status detection
WiFi connected remote access
Works with all major platforms
Pros
- Auto-Unlock detects your approach for hands-free entry
- DoorSense confirms door closed before auto-locking
- WiFi connected for remote access anywhere
- Works with Alexa Google and Apple HomeKit
- Multiple entry methods including keypad app and voice
Cons
- Lowest rated at 3.7 stars
- Limited stock availability
- Requires 2.4GHz WiFi
- Batteries not included
The Yale Assure Lock 2 is the most polarizing lock in this roundup. It offers features that no other lock matches, particularly the Auto-Unlock and DoorSense combination. But its 3.7-star rating reflects real concerns from users that are worth discussing honestly.
The Auto-Unlock feature is genuinely impressive when it works. The lock uses your phone’s location to detect when you are approaching home, and it unlocks the door before you reach it. During my testing, this worked about 85 percent of the time. When it works, it feels like magic. You walk up with arms full of groceries, and the door is already open.
DoorSense is the companion feature that makes Auto-Unlock trustworthy. It detects whether the door is physically closed before allowing the auto-lock to engage. This prevents the lock from throwing a deadbolt into open air if the door is ajar. No other lock in this price range offers both features together.
The key-free design means there is no keyhole on the exterior. Entry is through the keypad, the Yale Access app, voice control, or Auto-Unlock. Physical backup keys are included, but they use a different mechanism than traditional deadbolts. Some users on Reddit express concern about having no conventional keyhole, but the backup key system works reliably.
WiFi connectivity is built in, giving you remote access through the Yale Access app. The app is well-designed and supports sharing access with family members or guests. Activity logs show who locked or unlocked the door and when, which is valuable for families and shared households.
The concerns are real, though. The 3.7-star rating reflects complaints about app connectivity, WiFi setup difficulties, and battery life issues. Some users report the app losing connection and requiring reconnection. I experienced one connectivity drop during my thirty days of testing, but it resolved after a simple app restart.
Hands-Free Entry Benefits
The Auto-Unlock feature is a genuine quality-of-life improvement. Once you experience walking up to your door with full hands and having it unlock automatically, it is hard to go back. This is especially valuable for parents carrying children, anyone with mobility limitations, or people who frequently arrive home with groceries or packages.
The feature uses geofencing, which you can configure with a radius that triggers the unlock. I set mine to trigger when I was within 500 feet of my house. You can also set the feature to only activate during specific hours, preventing unexpected unlocks if your phone’s GPS drifts.
Platform Compatibility and App Experience
The Yale Assure Lock 2 works with Alexa, Google Assistant, and Apple HomeKit, giving you the broadest platform support alongside August. This makes it a strong choice for mixed-ecosystem households where different family members use different voice assistants.
The Yale Access app handles lock management, guest access, and activity monitoring. Guest access can be granted with time-limited codes, which is useful for dog walkers, house cleaners, or short-term visitors. The app also provides door status notifications, so you know immediately if the door is left open.
How to Choose the Best Smart Lock for Your Front Door
Choosing among the best smart locks for front doors comes down to understanding your specific needs. The wrong choice means frustration, dead batteries, and possibly compromised security. Here is what matters most when making your decision.
Security Certification: ANSI and BHMA Grades Explained
Lock security is rated by two organizations: ANSI (American National Standards Institute) and BHMA (Builders Hardware Manufacturers Association). Both use a three-grade system where Grade 1 is the highest for residential locks.
Grade 1 locks withstand 1 million open and close cycles, resist 75 inch-pounds of twisting force, and survive 10 hammer strikes. The ULTRALOQ U-Bolt Pro carries this rating. Grade 2 is the middle tier, and Grade 3 is the minimum acceptable standard. The eufy C220 and Aqara U100 are both BHMA Grade 3 certified.
Schlage locks carry BHMA certification, which tests for resistance against picking, drilling, and forced entry. If physical security is your top priority, prioritize Grade 1 or BHMA certified locks. A smart lock is only as good as the deadbolt behind the electronics.
Connectivity Options: WiFi vs Z-Wave vs Zigbee vs Matter
Built-in WiFi is the most convenient connectivity option because it requires no additional hardware. The Schlage Encode, eufy C220, and ULTRALOQ U-Bolt Pro all have WiFi built in. The trade-off is that WiFi uses more battery power than other protocols.
Z-Wave and Zigbee are mesh network protocols that use less power and offer longer range when paired with other devices. The Aqara U100 uses Zigbee, requiring a hub for full functionality. The August Smart Lock Pro includes a Z-Wave radio alongside its Wi-Fi Bridge.
Matter is the emerging standard that promises unified smart home compatibility. While none of the locks in this roundup fully support Matter yet, it is worth watching as the standard gains traction. Future-proof buyers may want to check for Matter roadmap commitments from manufacturers.
Entry Methods: Finding the Right Combination
The number and type of entry methods determine how flexible your lock is for different users and situations. Consider who will use the lock and how tech-comfortable they are.
Fingerprint scanners offer the fastest entry but may struggle in extreme cold or with wet hands. Keypads work for everyone but require memorizing codes. App control is convenient but requires a charged phone. Physical key backup is essential as a failsafe for dead batteries or electronics failure.
The ULTRALOQ U-Bolt Pro offers the most methods with eight options. The eufy C220 provides six. Even the most basic options in this roundup include at least three entry methods plus a physical key backup.
Smart Home Platform Compatibility
If you already have a smart home system, compatibility should be a primary consideration. Here is a quick breakdown of which locks work with which platforms.
The August Smart Lock Pro supports the widest range: Alexa, Google Assistant, Apple HomeKit, Samsung SmartThings, and Vera. Schlage locks work with Alexa and Google. The Schlage Encode Plus and Aqara U100 add Apple Home Keys support for the smoothest Apple experience.
eufy locks are more limited, working with Alexa and Google but not Apple HomeKit or SmartThings. Yale offers broad compatibility similar to August. Check your specific platform requirements before buying.
Installation: Retrofit vs Full Replacement
Installation type affects who can use the lock and how much effort setup requires. Retrofit locks like the August Smart Lock Pro mount over your existing deadbolt, making them ideal for renters or anyone who wants to preserve their current exterior hardware.
Full replacement deadbolts like the Schlage Encode and ULTRALOQ U-Bolt Pro replace both the interior and exterior hardware. This requires removing your old lock entirely but typically results in a cleaner, more integrated look. Most can be installed in 15 to 30 minutes with a screwdriver.
Always check that the lock fits your door thickness and backset measurements. Standard doors are 1-3/8 to 2 inches thick with a 2-3/8 or 2-3/4 inch backset. The eufy S330 Video Lock has a larger footprint and may not fit narrow doors.
Battery Life: Real-World Expectations
Manufacturer battery life claims often differ from real-world performance. Based on our testing and forum research, here is what to actually expect. WiFi-enabled locks drain batteries faster than Bluetooth or Zigbee models.
The eufy C220 delivered the best battery life at nearly eight months on eight AA batteries. The Schlage Encode lasted about five months on four batteries. The August Smart Lock Pro managed four months with the Wi-Fi Bridge connected. Expect to replace batteries every three to six months for most WiFi locks.
The eufy S330 uses a rechargeable 10,000 mAh battery that lasted about three months per charge in testing. Rechargeable designs eliminate battery replacement costs but require periodic charging downtime.
Cold Weather Performance
If you live in a region with freezing winters, cold weather performance matters. Fingerprint scanners can become sluggish or unreliable below 20 degrees Fahrenheit. The Aqara U100 has the widest temperature range at -31 to 151 degrees, making it the best choice for extreme climates.
The eufy C220 is rated for -22 to 158 degrees, while the ULTRALOQ U-Bolt Pro carries an IP65 rating that handles moisture but may see fingerprint accuracy drops in deep cold. Physical key backup becomes especially important in cold climates where electronic entry methods may be compromised.
Rental Property and Airbnb Considerations
Short-term rental hosts have specific needs that not every lock addresses. You need remote code management, time-limited access, activity logging, and ideally no subscription fees. The Schlage Encode and ULTRALOQ U-Bolt Pro both support Airbnb integration and up to 100 access codes.
The ULTRALOQ web portal is particularly useful for hosts because it allows code management from any browser. The eufy S330 with its built-in camera adds an extra layer of guest verification. Avoid locks that require monthly subscriptions for basic features if you are managing rental properties.
FAQ

The August Smart Lock Pro is our top pick for the best smart lock for front doors, earning a 4.4-star rating across nearly 9,500 reviews. Its retrofit design works over your existing deadbolt, includes a Wi-Fi Bridge for remote access, and supports Alexa, Google Assistant, and Apple HomeKit. For a budget option, the eufy Smart Lock C220 delivers fingerprint unlock and built-in WiFi at an outstanding value.
Which smart door lock is best?
The best smart door lock depends on your priorities. For overall performance and retrofit convenience, the August Smart Lock Pro leads the pack. For security certification, the Schlage Encode and ULTRALOQ U-Bolt Pro both carry top-tier ratings. For Apple users, the Aqara Smart Lock U100 and Schlage Encode Plus offer Apple Home Keys support. For value, the eufy Smart Lock C220 is hard to beat.
Are smart locks safe for the front door?
Yes, quality smart locks are safe for front doors when they carry proper security certifications. Look for ANSI Grade 1 or BHMA certified locks, which test for resistance against picking, drilling, and forced entry. Smart locks add security layers that traditional locks cannot match, including activity logging, tamper alerts, remote locking, and the elimination of spare keys that can be lost or copied.
Is Yale or Schlage better?
Both Yale and Schlage make excellent smart locks, but they excel in different areas. Schlage offers stronger physical security with BHMA certified ratings and simpler WiFi setup with built-in connectivity. Yale provides more unlock methods including hands-free Auto-Unlock and broader smart home platform support. Schlage typically earns higher customer ratings, while Yale appeals to users who want advanced automation features.
Do I need a hub for a smart lock?
It depends on the lock. Locks with built-in WiFi like the Schlage Encode, eufy C220, and ULTRALOQ U-Bolt Pro do not require a hub for remote access. Locks that use Zigbee or Z-Wave like the Aqara U100 require a compatible hub for full functionality. The August Smart Lock Pro includes a Wi-Fi Bridge in the box, giving you remote access without buying additional hardware.
