Four ways in. None of them a key.
Bedroom doors, home offices, rental turnovers — all the same problem. You're managing keys for a door inside your own building. Someone loses one. Someone needs one at 11pm. Someone gets a copy made you never approved.
This replaces the handle you already have. Your fingerprint opens it. So does a passcode, the app, or the key in the box if everything else fails.
Four Ways In
Fingerprint
Touch and it opens. Everyone in the house registers their own — no keys to hand out or take back.
Passcode
Keypad entry for wet hands or gloves. Temporary codes expire on their own after a guest is done.
Tuya app
Add and remove users from your phone through Tuya or Smart Life.
Backup key
Mechanical keys included, plus a Type-C port on the outside for emergency power.
Two Modes
Passage mode leaves the door unlatched for shared rooms you're in and out of all day — living rooms, playrooms, common areas.
Private mode restricts entry to the admin only. A bedroom, office, or storage room stays yours.
Measure Before You Order
This fits standard wooden interior doors with a 2.36"–2.75" backset. The backset is the distance from the edge of the door to the center of the handle hole — measure yours before ordering.
If your door already has a standard handle cut, this swaps in with a screwdriver. If it doesn't, you'll need the hole cut first. This is an interior door handle, not an exterior deadbolt.
Power
Battery powered with a low-battery alert well before it runs down. The Type-C port on the outside face means a dead battery doesn't lock you out — plug in a power bank and it opens while charging.
In the box
Everything you need, nothing you don't.

Why We Built This
LockNest started with the same problem everyone has — keys you lose, combinations you forget, and locks that feel like a suggestion instead of security.
So we built a store around locks that open when you touch them. Simple products, honest specs, tracked shipping, and a real inbox if something goes wrong.
Everything you need to know is on this page — the measurements are listed above so you can check the fit before you order.
