The 3-IN-1 Smart Door Knob offers a versatile solution to meet your diverse needs, featuring a fingerprint door lock with three unlock options: fingerprint unlock, app control (compatible with the Tuya App), and physical keys. This biometric door lock has made your life a bit easier, both improving home security and facilitating entry into your house.

The Fingerprint Quick Unlock feature allows you to reach your unlock within 1 second, complemented by a 5-second auto-locking feature to ensure your home's safety. Setting up the smart lock with your fingerprints is a breeze, with a memory capacity of up to 100 fingerprints, providing easy access for the entire family without the need to carry keys everywhere.

The Bluetooth APP Smart Control feature enables you to easily manage your fingerprints and unlock your door using your phone. With Bluetooth connectivity, you can check operation records, set auto-lock, and authorize administrators, helping you create a smarter and more convenient life while keeping your home secure. The control is limited within the Bluetooth range.

The Easy Installation process is designed to fit U.S. standard doors with back panel sizes of 2-3/8" (60mm) and 2-3/4" (70mm), and door thicknesses from 1-3/8" to 2-1/8" (35mm-54mm). With just a screwdriver, you can replace your door lock, and the package includes a detailed installation manual and technical support to facilitate the process.

The Auto Lock & Mute Mode feature offers added convenience and security. The 5-second auto-lock function ensures your home's security, even when you're in a hurry. Additionally, the Mute mode allows you to silence the lock sounds temporarily, creating a peaceful atmosphere, especially during late-night returns.

The Secure Privacy feature of the biometric access ensures that only authorized individuals can enter, providing a secure and peaceful space. You can install the fingerprint door knob on an inside pantry door to keep the little ones away from tempting snacks.
