Tuya Bluetooth Smart Knob Lock with Fingerprint Keypad

Built for quick upgrades on single-hole interior doors, this smart knob lock combines a compact keypad layout with biometric access for everyday convenience. The round knob format keeps the look familiar while adding modern entry options that work well for bedrooms, home offices, rentals, and light commercial rooms. Unlock the way you prefer: fingerprint for fast touch entry, PIN codes for guests, a physical key for backup, and Bluetooth app control for management. When paired with a compatible ecosystem, it can also support voice control for hands-free access in connected homes. Designed for simple replacement, the adjustable latch helps fit common backset sizes without complex door prep. A built-in emergency power interface adds a safety layer if the batteries run down, so access can be restored when needed.
