12-Pack Biometric Door Lock

This Buoan YL-52-Black kit supplies twelve identical smart locks for multi-door deployments. Each unit measures 6.34 by 2.6 by 2.6 inches and uses an aluminum body with a black finish. The locks suit property managers or large households needing consistent keyless entry across many openings.

Replaces Traditional Cylinders

The system removes the need for physical keys by offering five unlock methods: fingerprint, app, password, NFC card and mechanical backup. Up to 200 users can be enrolled with a maximum of 100 fingerprints stored per lock. Biometric verification completes in 0.3 seconds, making the upgrade worthwhile where key management has become a bottleneck.

Battery-Powered Standalone Fit

Four 1.5 V alkaline cells power each lock independently, so no wiring or central controller is required. A Type-C port provides emergency power if cells are depleted, while the auto-lock function engages automatically after every entry. The design fits standard door prep without additional drilling or mortise changes.

Questions about this item

What door thickness and backset does the 6.34 in x 2.6 in x 2.6 in lock body fit?

The lock measures 6.34 in x 2.6 in x 2.6 in and is designed for standard residential door preparations; verify your door thickness and backset match the included template before drilling.

Which step in the fingerprint enrolment process do users most often skip?

The first three enrolled users become administrators; if you skip assigning admin rights during initial setup, later user management and passage-mode changes require a factory reset.

How often must the four 1.5 V alkaline batteries be replaced, and what emergency power option exists?

Replace batteries when the red low-battery indicator lights; a Type-C port allows emergency unlocking with a portable charger but does not recharge the internal cells.
