5-in-1 Smart Door Knob with Biometric Access

This Meterk smart door knob combines fingerprint recognition, password entry, IC card access, mechanical keys, and Tuya app control in a single unit. It stores up to 100 fingerprints and 50 passwords for family members and guests. The lock fits wooden doors between 1.18" and 1.97" thick and measures 5.5 in x 5.5 in x 5.5 in.

Fingerprint Speed and Power Constraints

The 360° live fingerprint sensor unlocks in .2 seconds with a 99.7% accuracy rate. The lock operates on a 12 V power supply and includes a USB port for emergency power from an external power bank, though this port cannot recharge the internal batteries. An administrator fingerprint must be registered before first use.

Door Compatibility and Setup Requirements

Verify your door thickness falls within the 1.18"-1.97" range and that it is an out-opening, narrow-stile, or store-front style door. The package includes installation tools and video tutorials for a no-drill, no-wiring fit. Ensure you have a power bank available for the emergency USB port if batteries fail.

Questions about this item

Which unlocking method should I rely on most — fingerprint, app, code, IC card, or mechanical key?

The lock supports up to 100 fingerprints and 50 passcodes plus two mechanical keys and IC cards; register an admin fingerprint first, then add the methods your household uses most.

What does the 0.2-second fingerprint speed mean when I reach the door?

The sensor reads a live fingerprint in 0.2 seconds with 99.7% accuracy, so the bolt retracts almost the moment your finger touches it.

Does the Tuya app need Wi-Fi, Bluetooth, or a hub to control the lock?

The lock pairs with the Tuya app on your phone; the app handles remote access and entry logs through your home network.
