3-IN-1 Smart Door Knob: The Ultimate Fingerprint Lock with Multiple Unlock Methods

This 3-IN-1 smart door knob features three unlocking methods: fingerprint, app control (works with Tuya App), and physical keys. This flexibility meets a variety of needs and enhances home security. The biometric door lock makes life easier by ensuring both security and convenience.

Fingerprint Quick Unlock: Experience the convenience of fingerprint quick unlock with this smart door knob. You can unlock within 1 second and enjoy a 5-second auto-lock feature for added safety. Setting up fingerprints is easy, and the device can store up to 100 fingerprints. This ensures easy access for the entire family, reducing the need to carry keys everywhere.

Bluetooth APP Smart Control: Control your fingerprint door knob via your smartphone with Bluetooth support. Manage fingerprints easily through the Tuya App, and unlock your door with your phone. Check operation records, activate auto-lock, and authorize admins to create a smarter and more convenient life while keeping your home secure. Note: Control within Bluetooth range is required.

Easy Installation: Designed to fit standard U.S. doors, this smart door knob is easy to install. It requires a screwdriver and fits 2-3/8" to 2-3/4" (60mm to 70mm) back plates and 1-3/8" to 2-1/8" (35mm to 54mm) door thicknesses. The package includes a detailed installation manual and technical support for a seamless installation process.

Auto Lock & Mute Mode: The biometric door knob automatically locks within 5 seconds, ensuring you never forget to lock the door. Activate Mute mode to temporarily silence lock sounds, maintaining a peaceful atmosphere, especially for late-night returns.

Secure Privacy: Biometric access provides peace of mind by allowing only authorized individuals to enter. Install fingerprint door knobs on your pantry door to keep children away from snacks.
