Five-in-one access for home entry

The Buoan YL-52-Black smart door lock provides five ways to unlock: fingerprint, app, password, NFC card, and mechanical key. It stores up to 200 users including 100 fingerprints, making it suitable for families or small offices needing flexible, keyless entry without wiring.

Fingerprint speed and capacity

Biometric unlocking completes in 0.3 seconds using a 160 by 160 sensor. The lock holds a maximum of 100 fingerprints within the 200-user total, and the first three enrolled users become administrators who control permissions and passage-mode settings.

Battery-powered with emergency backup

Four 1.5 V alkaline batteries power the unit; a red indicator warns when replacement is needed. A Type-C port allows emergency unlocking from a portable charger, while the mechanical key provides a final fallback. The zinc-alloy body measures 6.34 by 2.6 by 2.6 inches and weighs 0.798 kilograms.
