The problem
A key is a single point of failure. Lose it and you're locked out. Lend it and you've lost control of who copies it. Get robbed and you're paying a locksmith to re-key every door in the house.
It gets handed to a babysitter and never comes back. It's copied at the hardware store and you never find out. It falls out of a kid's backpack somewhere between school and home. Each moment is a small security hole, and a traditional lock has no way to close it.
The solution
This keyless entry door lock is a 4-in-1 deadbolt lock: fingerprint, keypad code, smartphone app, and a physical backup key, all in one unit that replaces your existing deadbolt. Unlike bolt-on smart-lock systems, it's not a gadget that sits next to your lock — it is the lock, so you lock and unlock from one place.
Advanced biometric technology stores up to 100 unique fingerprints, learns the subtle variation in how you place your thumb, and improves match accuracy with use. A child's smaller print, an adult's wider one, a finger placed slightly off-center — the reader adapts instead of rejecting you at the door.
Access methods
Different moments call for different methods. You're never stuck with one.
The one you'll use 95% of the time. Walk up, touch, in. The reader sits where your thumb naturally lands — no fumbling in the dark. Wet, cold or dusty, the capacitive sensor handles real-world fingers far better than older optical pads.
The backlit electronic keypad deadbolt lets you create keypad-door codes instead of cutting keys — permanent for family, recurring for the cleaner, one-time for the delivery driver. Anti-peep entry lets you pad a real code with random digits so no one over your shoulder can memorize it.
Connects over Bluetooth at the door and, with the optional Wi-Fi hub, over the internet from anywhere. App remote control and app access let you lock or unlock the door remotely, see a time-stamped log of every entry, get a push notification each time the door opens, and add or delete codes without touching the lock.
Turn on auto-lock and the deadbolt re-engages on its own after a delay you set — 10 seconds, 30, a minute. No more lying in bed wondering whether you locked up. It's the single most popular setting among owners.
Technology should never trap you outside your own home. A concealed keyway accepts a traditional physical key as the ultimate fallback — the safety net that makes going keyless feel safe in the first place.
How it works
Press the same finger several times at slightly different angles so the lock captures a complete map of your print. Each scan takes a couple of seconds — enough capacity for a large family, a shared house, or a small office.
The sensor is always listening. The moment skin touches it, the lock wakes, matches the print against its stored templates, and drives the motor. The whole cycle is faster than turning a key.
Once you're inside, auto-lock takes over. After your chosen delay the smart deadbolt throws itself and the door is secure again — no button, no app, no thought required.
Why it wins
With four ways in before you ever touch the backup key, getting locked out essentially stops being possible. Your fingerprint is always with you. Your code is in your head. Your phone is in your pocket. Keyless entry for the whole household — including the people who could never be trusted with a key.
Grant a contractor a code for the duration of a renovation and let it expire. Pull access the moment a rental guest checks out. With app control you're not guarding a door — you're administering it.
The lock logs every event and can push a notification each time the door opens, by whom and when. For parents that means knowing the kids are home; living alone, it means an alert if the door opens when it shouldn't.
The most common way homes get burgled isn't a picked lock — it's an unlocked door. Auto-lock closes that gap permanently. The door secures itself whether or not you remember, whether or not your hands are full.
Security
A semiconductor capacitive fingerprint sensor with a false-acceptance rate low enough that the odds of a stranger's finger opening your door are vanishingly small. It reads the live electrical pattern of a real fingertip, so a photo or flat copy won't fool this biometric door lock.
Your fingerprint is never stored as an image and never leaves the lock. Enrollment converts your print into an encrypted template that lives only on the secure chip. There's no fingerprint database in the cloud to breach — because it was never uploaded.
Pad your real PIN with random digits so a shoulder-surfer can't learn it. Too many wrong codes freezes the keypad for minutes. A tamper alarm sounds if someone tries to pry the lock off the door — layered security features that take your home security seriously.
Rated against dust and water jets from any direction, and tested across a wide temperature range — so the reader keeps working through summer heat and winter cold on an exposed front door.
“A lock you can't trust in the rain isn't a lock — it's a fair-weather gadget. Weatherproofing is the line between a real entry door lock and a toy.”
— common refrain among smart-home installers
Connected
Pair the lock with Amazon Alexa or Google Assistant and check the door's status or lock it by voice — “Alexa, is the front door locked?” Unlocking by voice requires a spoken PIN, so a casual command from outside can't open your house. Drop it into a “Goodnight” routine to lock up, dim the lights and arm your other devices in one phrase.
The optional smart hub bridges the lock's Bluetooth to your Wi-Fi (WiFi) for true remote access. Without it, everything still works locally over Bluetooth — the hub simply extends the range from “at the door” to “anywhere in the world.” It plays nicely with the rest of your smart devices, which is why it ranks among the best smart locks for front door use.
Design
This smart fingerprint door lock is a recognition-door upgrade that looks like it belongs — security shouldn't mean an ugly box bolted to your door.
Replaces a standard single-cylinder deadbolt — the most common front-door choice.
A full handle set — a door handle with the fingerprint reader built into the lever for a one-piece look.
A knob-style biometric door knob for interior and lighter-duty doors — perfect as a bedroom door lock.
Installation
This door lock is easy to install: if you've ever changed a deadbolt, it's the same job. The simple installation needs a Phillips screwdriver and about twenty minutes — no drilling, no wiring, no electrician. Easy installation drops into the universal 2-1/8" bore your door already has, and the app keeps the door lock easy to use day to day. It's the rare door lock easy to install in one sitting.

The honest takeaway: eufy and Yale make excellent locks, and budget options like the veise fingerprint door lock or the ghome smart fingerprint door lock cover the basics. Where this one tends to win is the combination of a true fingerprint reader, a physical-key fallback many rivals dropped, USB-C emergency power, and Alexa plus Google Assistant — usually at a lower price than the Assure Lock 2 or a comparable ghome smart model.
Power
The fear that stops people buying a smart lock: “what happens when the battery dies?” Here's exactly how it's handled.
Roughly 8 months — about 8,000–10,000 unlock cycles — on the rechargeable battery. Low-battery warnings hit the keypad and app at 20% and 5%.
If it dies anyway, a USB-C port on the underside takes a quick jolt from any power bank or phone charger — enough to unlock and get inside.
Fingerprint unlock, keypad codes, auto-lock and the physical key all work with zero internet. Wi-Fi only adds the remote features.

Reviews
“Installed it in a Saturday morning before coffee was cold. The auto-lock alone is worth it — I'll never lie awake wondering if I locked up again.”
Verified homeowner
“I host two short-term rentals. I send each guest a keypad code that expires at checkout. No more key handoffs, no more lockbox codes the whole street knows.”
Airbnb host
“My kids get home before me. They just touch the door. No keys to lose, and I get a notification the second they're inside.”
Parent of two
Across thousands of reviews, the highest-praised single feature is the speed and consistency of the fingerprint recognition — the one thing that, if it failed, would sink the product. It doesn't.

FAQ
Yes, for two reasons. Your fingerprint is stored only as an encrypted template on the lock's secure chip — never an image, never uploaded to the cloud, so there's no online database to steal. And the lock itself adds a tamper alarm, keypad lockout after repeated wrong codes, and anti-peep code entry. Auto-lock also eliminates the most likely attack on any home: an unlocked door.
You're never locked out. The lock warns you well in advance via keypad and app alerts. If it dies anyway, a USB-C port gives instant emergency power from any phone charger or power bank, and a concealed physical key is the final fallback. The rechargeable battery lasts about 8 months between charges.
In most cases, yes — the capacitive reader handles damp, cold and lightly dirty fingers far better than older optical sensors. For the rare day a finger won't read, you simply use the keypad code, the app, or the physical key. Four ways in means a finicky fingerprint is never a problem.
Up to 100 unique fingerprints and a large set of keypad codes — permanent, recurring and one-time temporary. That covers large families, shared households, small offices and rental turnover with room to spare.
Completely. Fingerprint unlock, keypad access, auto-lock and the physical key all work with no app, no Wi-Fi and no account. The smartphone app and Wi-Fi hub are optional layers that add remote access, entry logs and notifications.
It fits standard doors prepped for a deadbolt (the universal 2-1/8" bore) and handles door thicknesses from 35mm to 55mm with included spacers. If your door already has a deadbolt, it will almost certainly fit — just measure the thickness before ordering.
