An automatic door lock exists to ditch keys and codes for your front door. The best ones read your hand, face, or phone and auto-lock the moment the door closes. Beyond that, the smart-lock aisle splits hard on how they let you in and how they stay powered.
I’m Mohammad Maruf — the founder and writer behind KitchPrep. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
The biometric verification and auto-lock behaviors are the deciding factors for the automatic door lock you should trust with your home’s entryway.
Our Picks at a Glance



How To Choose The Best Automatic Door Lock
Before you buy, know that not every smart lock is actually “automatic.” Some just replace your key with a code pad and still need you to twist a knob. True automatic locks engage the deadbolt by themselves and often open up without you touching anything.
Pick your “hands-free” method
The biggest split is how the lock lets you in. Palm-vein readers scan the unique blood-vessel pattern under your hand, so they work even with gloves on. Facial recognition cameras open up when you walk up. Fingerprint sensors are fast but fail with wet or dirty fingers. Choose the lock that matches how you arrive home.
Check the auto-lock sensor
A gyroscope inside the lock senses the door’s angle and movement, locking it the instant it swings shut without a separate door sensor. Other models rely on a magnetic door sensor that must be installed and aligned on the frame. If you can’t position the sensor correctly, the door won’t auto-lock.

In-Depth Reviews
1. Wyze Palm Lock
Our pick — over 4.5★ from 750+ verified ratings; the strongest balance of quality and price.
The contactless palm reader that waves you in without ever touching a keypad.
This is the lock for anyone who wants the “wave and walk in” experience. It reads the unique vein pattern beneath your palm, so it works flawlessly even with wet hands or gloves, and owners say the scanning beats their old fingerprint locks. The standout feature is the auto-lock gyroscope, which senses the door’s angle and movement to bolt it shut the instant it closes, preventing false or jammed locks.
The power system is a serious point in its favor. It runs on a 6-month main battery backed by a 2-week secondary battery, and if both somehow drain, you can use the integrated USB-C port with any power bank for an emergency charge so you’re never locked out. It also packs a millimeter wave radar (the same tech used in self-driving cars) that scans for the presence of a person, not just movement, so the lock only “wakes up” when someone actually approaches.
What wins people over is the sheer functionality — it’s a high-end smart lock without the high-end hassle, earning a 4.6-star crowd favorite across 700+ owners. The keypad lets you create up to 50 unique or one-time guest codes, and Anti-Peep Technology lets you type extra digits before or after your real PIN to hide it from snoopers. The catch? Buyers report that with a storm door, the battery can drain in roughly 1.5 months unless you use Super Battery Saver mode (tap to wake), which improves response and stretches the charge.
Why it’s the pick
- Contactless palm-vein reading works with gloves or wet hands
- Gyroscope auto-locks the moment the door closes
- Dual-battery system plus USB-C emergency charging
Know before you buy
- Battery can drain fast with a storm door unless you enable Super Battery Saver
- Wi-Fi needed for remote control; palm and codes work offline
Reach for this if: you want hands-free entry that works in any weather and an auto-lock you can trust without a separate door sensor.
Look elsewhere if: you live behind a storm door and don’t want to manage battery saver settings.
2. Veise VE06-L Smart Deadbolt Lock with 2 Lever Handles
The rental-property workhorse that hands out codes and IC cards like a property manager’s dream.
This lock is built for landlords juggling tenants and short-term guests. It open up via the app, codes, a web portal, IC cards (with a 1,000+ card capacity), e-keys, an authorized admin, or a key, and it even works with an Apple Watch. The auto-lock is adjustable from 5 to 900 seconds, and a one-touch lock by holding “#” for 2 seconds gives you quick manual control. Solid zinc alloy construction gives it a premium feel for the price.
The headline feature is the code flexibility. You can store 250+ codes, creating permanent, scheduled, recurring, or one-time codes that delete after use, all managed remotely. Anti-peeping protection lets you add random digits before or after the code, and the lock disables for 2 minutes after 5 wrong attempts to stop brute-force guessing. Remote access and voice control with Alexa or Google Assistant require the G2 gateway (sold separately), but the core lock functions are subscription-free.
Owners consistently praise two things: the 79 owners highlighting installation and 40 highlighting the appearance. The review pages sum it up: “Easy install, clear instructions, includes all but screwdriver.” The lever handle set adds a touch of class to the front door, and owners mention it looks high-end. The honest trade-off is the connectivity, which draws mixed feedback — the smart features rely on the separate gateway, and customers note that professional installation is recommended if you’re not handy.
Strong points: It’s a landlord’s toolkit in one box — IC cards, 250+ codes, and remote management via the DDlock app with no subscription fee.
Heads up: For full remote access you’ll need the G2 gateway, and some owners found the programming instructions weak until support helped.
Best for: rental property owners and managers who need to cycle codes and cards for many different people.
Think twice if: you want remote locking straight from the start, since the G2 gateway is an extra purchase.
3. Veise VE017-L Fingerprint Smart Lock with 2 Lever Handles
The 0.2-second fingerprint reader that beats most keys to the latch.
This 8-in-1 lock is about speed. The fingerprint sensor uses AI self-learning to recognize your print in 0.2 seconds with 99.99% accuracy., and the FPC sensor with 500DPI resolution reads at any angle. That means you can tap and turn the handle in one fluid motion — no fumbling for keys in the rain. The zinc-alloy handle feels solid in hand, and the package includes two handles so you can upgrade your whole entry set at once.
Battery life is the quiet hero here. Four AA batteries (not included) last up to a full year of daily use, with low-battery alerts and a Type-C emergency charging port so you’re never caught locked out. It manages 100+ permanent or recurring codes through the KK Home app, plus unlimited temporary or one-time codes you can generate and share remotely. The auto-lock is adjustable from 10 to 180 seconds, letting you dial in exactly when the bolt throws.
The thing everyone raves about is the variety of ways to open it, which reviewers point out is especially great for elderly family members who struggle with keys. Build quality is strong with IP55 waterproofing and ANSI Grade 3 & BHMA standards, performing consistently from -35°F to 160°F. The catch is that remote lock/open up requires the Veise G1 Gateway (sold separately), and Bluetooth connectivity earns mixed feedback, with several owners reporting disconnection issues.
Why it stands out: You get a fingerprint read in just 0.2 seconds, so you are inside fast, and the battery lasts 12 months, so you rarely think about recharging.
Fair warning: The Bluetooth connection has its critics, and you’ll want the G1 gateway if remote access matters to you.
Choose it for: the fastest fingerprint entry in this lineup and a full year of battery before you think about AA swaps.
skip it if: you’re deep in the Apple HomeKit ecosystem and need native HomeKit support.
4. Tapo Smart Wi-Fi Door Lock DL110
The one-year rechargeable battery champion that makes battery anxiety a thing of the past.
This lock from TP-Link solves the single biggest smart-lock annoyance: constant battery swaps. It runs on a removable, rechargeable battery pack that delivers a full year of continuous operation, and the app shows you the exact battery level. One owner reported their battery still sat at 60% after a year of daily use. That longevity means you can install it and forget about power for 12 months.
It offers six ways to get in: fingerprint recognition, custom passcodes, Wi-Fi management from anywhere, close-range Bluetooth, your smart home assistant, or the included backup keys. The fingerprint sensor open up in just 0.42 seconds and remembers up to 100 different fingerprints — enough for the whole extended family. Setup is genuinely fast, with owners reporting a simple 10 to 15-minute install, and it works with the same Tapo app that runs TP-Link’s mesh routers and cameras.
Buyers praise the ease of installation and the straightforward app interface, calling it a great upgrade even for first-time smart lock owners. The fingerprint reader is described as fast, and the auto-lock has a few delay presets to choose from. A few owners note the fingerprint sensor can be finicky at certain angles, and the lock may need minor wood scraping for a perfectly flush fit on some doors. Overall, it’s a sturdy, thicker lock mechanism that integrates cleanly with the broader TP-Link smart home ecosystem.
What owners love
- Rechargeable battery that lasts a full year
- No extra hub needed — built-in Wi-Fi
- Six different access methods including backup keys
What to watch
- Fingerprint reader can be finicky at certain angles
- Auto-lock has limited delay presets
Reach for this if: you hate changing lock batteries and want a rechargeable pack that lasts a year.
Look elsewhere if: you need granular auto-lock timing beyond a few preset delays.
5. Philips WiFi Keypad Deadbolt with Handle, 4200 Series
The Philips that beams remote access straight to your phone, no extra hub or bridge required.
This is the pick for people who want remote control without buying another gadget. It connects directly to your 2.4GHz Wi-Fi network, so there’s no hub or bridge to set up. The Philips Home Access App lets you lock or open up from anywhere, manage user codes and fingerprints, check real-time door status, and scroll through access history whether you’re at work or on vacation. One caveat: keep it within 33 ft (10 m) of your router, minimizing walls and metal obstacles for a strong connection.
Entry options are versatile. The fingerprint sensor open up in 0.3 seconds, and you can store prints for the whole family. The keypad supports permanent, one-time, periodic, and recurring PIN codes, making it perfect for guests, housekeepers, or an Airbnb setup. Voice control via Alexa or Google Assistant means you can lock up hands-free while carrying groceries. The auto-lock is adjustable from 0 to 180 seconds through the app — though it ships with Auto-Lock off by default, so you’ll want to enable it in the app.
Buyers describe the matte black finish as making the lock “look expensive,” and 139 owners highlight the easy installation. The battery life runs up to 6 months on standard 1.5V alkaline batteries (not included), with an intelligent low-battery alert. You should stick to alkaline only — the manufacturer warns against rechargeable or high-power lithium batteries. The recurring gripe is battery life, which shows as the most negative aspect, so expect to swap AAs a couple of times a year.
Standout feature: Built-in Wi-Fi means no hub purchase, and the included lever handle set makes it a complete front-door upgrade.
Honest caveat: Battery life is the most common negative theme, and the lock must stay close to your router.
Best for: households that want app control without adding a hub gadget to their Wi-Fi setup.
Think twice if: you want a full year between battery changes — plan for roughly 6-month intervals here.
6. Philips Smart Deadbolt Lock with 2 Lever Handles, DDL240X
A two-handle set that upgrades your levers and your deadbolt in one screwdriver session.
This lock gives you four ways in — fingerprints, PIN codes, keys, and the app — all while replacing your existing door handles with a matching lever set. The aluminum handle feels premium, and owners describe a sturdy metal build with a motor that’s audible but not annoying. Up to fifty fingerprints can be stored, and the keypad supports 100 user PINs plus unlimited one-time PINs that auto-delete after a single use.
It’s a Bluetooth-first lock, so the built-in Bluetooth works within 8–10 meters of your phone. For remote control, voice commands, or sharing timed and recurring PINs, you’ll need the Philips WiFi Gateway (sold separately). Auto-lock does exist, but there’s no sensor — you must ensure the door is fully closed before it engages, a point the manufacturer stresses for safety. Install fits most standard doors from 1-3/8″ to 1-3/4″ thick using just a screwdriver.
The review picture is genuinely split. Many buyers find it reliable, convenient, and perfect for families, praising the responsive keypad and quick fingerprint accuracy. Others report the biometric reader is finicky — some fingerprints stop being recognized over time or occasionally get rejected. The Philips app itself draws some criticism for being glitchy, though shoppers say the customer service team resolves the issues well. It’s a solid choice if you’re okay with occasional fingerprint retries and value the complete handle set.
What stands out
- Complete lever handle set included
- Unlimited one-time PINs that auto-delete after use
- Compatible with most standard doors
What’s mixed
- Fingerprint reader earns genuinely mixed reviews
- Auto-lock has no sensor, so the door must be fully closed first
Choose it for: a full entry-set upgrade with four ways to open up at a budget-friendly price.
pass on it if: fingerprint reliability is your make-or-break feature — treat this as good but occasionally imperfect.
7. Yale Assure Lock 2 Keypad Smart Deadbolt with Wi-Fi
The Yale that plays perfectly with Apple HomeKit, Siri, and your Apple Watch.
This is the lock to grab if your smart home runs on Apple. It works with the Apple Home app and Siri, and you can open up it from your Apple Watch. Set up an Apple TV, iPad, or HomePod as a hub and you get remote access from anywhere. It also answers to Amazon Alexa and Google Assistant. The Auto-open up feature senses when you arrive home and open up the door before you touch it — ideal when your hands are full of groceries.
The Auto-Lock works with the included DoorSense accessory, which detects when the door is actually closed before throwing the bolt. That’s a meaningful safety upgrade over locks that might lock while the door is still ajar. You can share unlimited codes with family and friends through the Yale Access App, and the activity feed tracks who comes and goes. Security features include two-factor authentication and matte keypads designed to resist fingerprint smudging.
The reviews are a split bag. Many owners love it as a smart home device, noting it locks itself when their hands are full. But reliability is the most-discussed concern, with some units reportedly stopping working completely after about three months and batteries draining faster than expected. The software gets called “fickle” — activity logs missing entries, DoorSense needing recalibration, and Auto-Lock misfiring in rare cases. It’s a capable lock with clean HomeKit integration, but if you need rock-solid reliability above all, the mixed reliability reviews are worth weighing.
Standout benefit: Native Apple HomeKit support means Siri, Apple Watch, and Home app control without extra hubs.
The trade-off: Reliability and battery drain are the most-frequent complaints in the review data, so this is the one to research carefully.
Reach for this if: you live in Apple’s ecosystem and want your deadbolt controlled by Siri and your Watch.
Look elsewhere if: you need absolute reliability — the review pattern shows some owners hit software and battery issues.
8. Schlage Encode Smart WiFi Lever, Century Trim
The lever lock that hosts Airbnb guests automatically and wipes their codes when they leave.
Short-term rental hosts, this is your lock. It integrates directly with Airbnb, auto-generating guest codes for each booking and auto-wiping them after checkout. No physical keys to hand off, no codes to remember to delete. The built-in Wi-Fi means control from anywhere via the Schlage Home app — lock up, let someone in, receive notifications, and share access without touching the door. Buyers report checking the lock status and battery percentage right from the app.
Security is serious here. It has an encrypted connection, a customizable alarm for door movement and forced entry attempts, and a fingerprint-resistant touchscreen. The auto-lock can relock the door for you with various time delay options, and convenient control buttons on the interior let you quickly set it to an open up state for frequent use. It holds the highest residential Security, Durability, and Finish rating from BHMA.
Owners call it “pro-grade” and note the lever action is silent compared to noisy deadbolts. Setup takes about 15 minutes with the app guiding you through, and there’s no hub needed. A few owners in humid climates report condensation in the battery compartment causing disconnects over 6-12 months, though customer service replaced the units. It also lacks a fingerprint reader, which is a deliberate design choice to avoid moisture-related sensor failures.
Why hosts love it: Native Airbnb integration auto-generates and auto-wipes guest codes, saving hours of manual access management.
Who it isn’t for: Anyone in a humid climate — condensation in the battery compartment has been reported.
Best for: Airbnb hosts and landlords who want automated guest-code management and a premium, silent lever lock.
Think twice if: you live somewhere very humid, where battery-compartment condensation has been reported.
9. Aqara UWB Smart Lock U400
The UWB lock that knows you’re approaching and swings the door open before you touch it.
This lock feels like it is from the future. UWB (Ultra-Wideband, a short-range radio that senses your exact position) detects you approaching, your direction, and your intent, then open up automatically — you never touch it. Owners mention it is 100% reliable, with no accidental open up, even when other signals interfere. It shines when your hands are full, you are wearing gloves, or you are arriving in the rain. The catch is the setup: UWB open up needs a Thread-enabled Apple Home hub, plus an iPhone 11 or later (excluding iPhone SE & iPhone 16e) running iOS 18.5+, or an Apple Watch Series 6 or later (excluding SE) on watchOS 11.5+.
Beyond UWB, it offers Apple home key tap-to-open up, fingerprint, touchscreen passcode, voice assistant control, remote app access, NFC card support (card sold separately), and a physical key. Built with Matter over Thread, it connects to multiple smart home platforms simultaneously — Apple HomeKit, Alexa, Google, Home Assistant, and SmartThings — with faster response and lower power consumption than plain Wi-Fi. The rechargeable lithium battery lasts up to 6 months per charge, and you can top it up via the USB-C port without taking the lock offline.
Reliability is the top praised aspect, with 132 owners highlighting it. Customers note the battery still sitting at 85% after 3 months and call the install easy. The recurring theme is installation connectivity, which is genuinely mixed — some find it simple while others report taking up to a week to get it connected, especially with Matter setup in the Aqara app. A few note the plastic interior feels cheap and the paint has overspray, and there’s a warning that a fragile gold connector can break during reinstallation. This is a “install once and leave it alone” lock.
What makes it special
- True hands-free UWB open up detects your approach
- Matter over Thread connects to every major smart home platform
- Rechargeable battery with USB-C top-up that doesn’t take the lock offline
What to know
- UWB open up requires a Thread-enabled Apple Home hub and recent iPhone/Watch
- Connectivity setup can take time, and the interior feels less premium
Reach for this if: you’re an Apple ecosystem devotee who wants the door to simply open as you walk up.
Look elsewhere if: you don’t have compatible Apple hardware, since the signature UWB feature won’t work.
10. Lockly Visage Zeno Smart Lock
The face-reading deadbolt that open up in seconds, even in pitch-black night.
Here’s the lock for people who want to walk up and have the door simply recognize them. Dual infrared sensors ensure facial recognition works accurately in any lighting, including total darkness, and your facial data is encrypted and stored securely on the device itself. Reviewers point out the face open up recognizes them in 1-2 seconds with zero connectivity issues, calling it the standout feature for hands-free entry. The included door sensor with magnets enables auto-lock, though the magnets need to be within 3/4″ of each other.
It’s a multimedia open up machine. Beyond the facial recognition, there’s a self-learning AI fingerprint sensor that recognizes prints in 0.2 seconds and stores up to 99 prints, plus the Lockly Home app, keypad, physical key, Apple Watch, and Alexa/Google voice. Apple Home Key support means you can tap your iPhone or Apple Watch to open up, even when your device is out of power. Built-in Wi-Fi means remote control without a bridge, and the whole thing installs in about 15 minutes per the maker (though owners suggest budgeting 2-3 hours for a first-timer).
The power design is outstanding. It runs on two 10000mAh rechargeable batteries, and shoppers say the first battery still sitting at 28% after 9+ months of use. That’s a dramatic improvement over locks that need new batteries every few weeks. Quality and reliability are the top praised aspects, with 137 and 110 owners respectively. The downsides are the price point, which some call “grossly expensive,” and a few cosmetic nitpicks like a cheap-feeling screen flap and an ugly door sensor. It also needs a 2.125″ deadbolt hole for installation.
What wins people over
- Face recognition works in any lighting, even at night
- Dual 10000mAh batteries last 9+ months per charge
- Apple Home Key tap-to-open up support
What’s less great
- Pricey, and some owners question the value
- Door sensor must be placed within 3/4″ of its magnet
Best for: tech-forward homeowners who want facial recognition and Apple Home Key in a premium, no-hub package.
Think twice if: budget is a primary concern — a few owners found the premium price hard to justify.
11. eufy Security Smart Lock FamiLock S3 Max
The lock, doorbell, and peephole in one — with a rear screen to check who’s outside.
This is the Swiss Army knife of door locks, combining a smart deadbolt with a 2K HD camera, an f/1.8 lens for night visibility, and a 150° Head-to-Toe wide-angle view that eliminates blind spots for package monitoring. The rear lock video screen lets you check the front door without opening your phone app — a simple, intuitive design that owners say is ideal for elderly family members and kids. It combines a lock, doorbell, peephole, and AI camera in one device.
Entry is via palm vein recognition, which scans your unique vein patterns in 0.6 seconds. Buyers report it’s accurate once you angle your hand correctly and mark the spot. All biometric data is stored locally on the lock, keeping your privacy in your hands. It also offers PIN, physical key, and wave-to-open up gesture options. The dual power system runs a rechargeable battery offering up to 4 months of full functionality, plus an emergency set of 4 AAA batteries for an extra month of essential function during power outages.
Quality is the top praised aspect with 130 owners highlighting it, and installation gets strong marks with 71 owners. The all-in-one nature is the big draw — multi-device functionality covering lock, keypad, palm reader, key, doorbell, peephole, and AI camera. The catch is the palm recognition is genuinely mixed; some find it fantastic, others call it basically useless until they learn the positioning technique. Connectivity also draws mixed feedback, with some owners reporting unstable connection to the HomeBase and Matter/Apple Home integration that fails with errors. This is a feature-rich pick with a learning curve.
Why it’s unique
- 2K HD camera with 150° Head-to-Toe view doubles as a doorbell
- Rear video screen for app-free front-door checks
- Palm vein open up in 0.6 seconds
What to weigh
- Palm recognition earns mixed reviews until you master positioning
- Matter/Apple Home integration can be unstable
Choose it for: a single device that replaces your lock, doorbell, peephole, and camera with local-storage privacy.
it’s not for you if: you want reliable Matter/Apple Home integration — owners mention connection issues there.
Understanding the Specs
Biometric readers: palm vs. face vs. fingerprint
Palm-vein readers scan the unique blood-vessel pattern under your hand, making them excellent for wet or gloved hands — they read what’s beneath the skin, not the surface. Facial recognition uses infrared sensors to map your face even in the dark. Fingerprint sensors are the most common and fastest, but they fail with wet, dirty, or calloused fingers. Your environment decides the winner: if you live in a rainy area, palm or face beats fingerprint.
Auto-lock sensors: gyroscope vs. door sensor
Some locks use a built-in gyroscope that senses the door’s angle and movement, locking the instant it closes without any extra hardware. Others rely on a separate magnetic door sensor you mount on the frame, like the DoorSense on Yale or the magnetic sensor on the Lockly. The gyroscope approach is simpler to install, but a door sensor can be more precise — when it works. If your door doesn’t align perfectly, a door-sensor lock may not auto-lock at all.
Battery and backup power
Battery life ranges dramatically — from 4 AA batteries lasting a year down to the Wyze’s 6-month main plus 2-week backup system. The best designs add a USB-C emergency charging port so you can power up with a power bank if you’re ever locked out. Some use proprietary rechargeable packs, like the Lockly’s dual 10000mAh batteries or the Tapo’s 1-year rechargeable pack. Look for low-battery alerts and a visible battery level in the app so you’re never caught by surprise.
Connectivity: Wi-Fi, Bluetooth, and Matter
Built-in Wi-Fi gives you remote control without buying extra hardware, like on the Philips 4200 and Schlage Encode. Bluetooth-only locks are cheaper but only work within 8–10 meters of your phone unless paired with a separate gateway (sold separately, common on Veise models). Matter over Thread, found on the Aqara U400, connects to every major smart home platform simultaneously with lower power draw. Check which protocol your smart home needs before you buy.
