Fingerprint Door Lock & Biometric Door Knob with App – 3-in-1 Keyless Entry Smart Door Lock with Auto-Lock & Interior Lockable, Secure Your Home, Office, Bedroom & Apartment Black

【3-in-1 Access Options 】: Unlock using fingerprint, app, or mechanical key. This biometric door lock stores up to 100 fingerprints with ultra-fast 0.3s recognition, providing secure and convenient entry for your family. 【App Control, Smarter Security 】: Unlock and manage users via the Tuya Smart App, view access logs, or activate silent mode. With Gavdhe fingerprint door knob, you stay in control of who enters your home—anytime, anywhere. 【App-Activated Interior Lockable & Auto-Lock】: Enable the interior lockable mode via the App for extra security—once activated, the fingerprint door handle cannot be unlocked from outside except by admin or mechanical key. Set an auto-lock delay (1–3 min) to ensure your home is automatically secured. 【Smart Control & Voice Unlock】: Pair with the Gavdhe gateway (sold separately) to control your lock remotely, monitor access logs in real time, and unlock hands-free with Alexa or Google Assistant. 【Long-Lasting Power & Emergency Backup】: Powered by 4 AAA Alkaline batteries for up to 12 months with low-battery alerts. The built-in Type-C emergency port allows temporary power via a power bank (cannot be used to directly charge batteries or operate the lock continuously), ensuring you’re never locked out. ›See more product details ›See more product details
