This is a keyless door knob that opens five ways: fingerprint, passcode, Tuya or Smart Life app, IC card, or a mechanical key. The upgraded sensor reads a fingerprint in about 0.3 seconds with a recognition area 1.8 times larger than the earlier design, and fingerprint data stays on the lock. It runs on four AAA batteries with up to 12 months of use, low-battery alerts, and a Type-C port for a power bank if the cells die. It suits bedrooms, rentals and interior doors where people want keyless entry without giving up a physical key. Against pricier smart deadbolts it lacks the heavier build and some integrations, but it offers more access methods than most keypad knobs at its level.

This is an electronic door lock with a handle, built for compatible interior doors. It offers five ways to unlock: fingerprint, passcode, the Tuya or Smart Life app, IC card, and mechanical key. It stores up to 200 fingerprints, passcodes and IC cards combined, and fingerprint data stays stored locally.
The upgraded fingerprint sensor has a 1.8× larger effective recognition area than the previous design. Recognition takes about 0.3 s, with up to 99.99% accuracy. The app manages users, creates temporary or permanent passcodes, and shows unlock records. Remote unlocking requires a compatible gateway, sold separately.
The lock runs on 4 AAA batteries, not included, for up to 12 months of battery life under normal use. Low-battery alerts tell you when to replace them. If the batteries run out, connect a power bank to the Type-C emergency port for temporary power. The port does not recharge the AAA batteries. Two mechanical keys give a backup that does not depend on the app, fingerprint sensor or battery power.
