Frequently Asked Questions
Q: Is this smart fingerprint door lock compatible with the Tuya app?
A: Yes — the Asia-Teco Q51 connects via Bluetooth to the Tuya Smart app (available on iOS and Android). You can manage users, generate temporary passwords, and monitor access directly from your phone. Gateway support is also included for expanded smart-home integration.
Q: What happens if the batteries die?
A: The lock features a built-in Type-C emergency power port. Simply connect a 5V DC power bank or charger to the port to temporarily power the lock and gain entry. The low-battery alert (LED flash + buzzer) will warn you well before this happens.
Q: Can multiple family members use this lock?
A: Absolutely. The lock supports up to 150 users across shared fingerprint and password slots — up to 50 unique fingerprints and 100 PIN codes. Three administrator accounts can manage all user credentials and access settings.
Q: Does this lock fit both left- and right-handed doors?
A: Yes. The handle direction is fully reversible, making installation straightforward on either left-handed or right-handed wooden interior doors. Drilling installation is required, and all necessary hardware is included in the screw bag.
Q: How does the anti-peep virtual password feature work?
A: You can enter random digits before or after your real 6-digit PIN. The lock only reads the valid code within the string, so onlookers cannot determine your actual password by watching your keystrokes — adding an extra layer of security in shared spaces.
