Smart Door Lock for 35-55mm Doors

This Computerzone smart door lock fits door thicknesses from 35mm to 55mm and replaces a standard knob without drilling. It unlocks via fingerprint or a smartphone app using Bluetooth, and includes a USB emergency charging port plus two mechanical keys for backup access.

Check Door Thickness and Power

Verify that your door is between 35mm and 55mm thick before ordering, as the lock is designed for this range only. The unit requires four AAA batteries, which are not included, and the app will show a low-battery reminder after roughly 7000 uses or about ten months.

Suits Homes Wanting Keyless Entry Without Wiring

Ideal for homeowners or renters who want fingerprint and app control on a front, bedroom or office door without running cables or changing the door prep. Not suitable for doors outside the 35-55mm range, for buyers who need built-in Wi-Fi remote access without buying a separate gateway, or for installations that require a mortise lock body.
