Fingerprint Door Lock Smart Door Knob - App & Biometric Access

Our review of this fingerprint door knob finds it best suited for interior doors where convenience and controlled access matter most. The biggest reason to buy is the fast, one-touch fingerprint recognition that replaces keys for up to 50 users while still including two physical back-up keys for emergencies. Installation is straightforward for bedroom, office, or apartment doors and the rechargeable battery design means low maintenance. The app and optional gateway add useful remote and voice control capabilities for people who want app-based user management and access logs.

Key Features

• Fingerprint Storage: Stores up to 50 fingerprint users so families or small offices can grant access without shared keys.
• One-Touch Unlock: Advanced fingerprint recognition gives fast entry with a single touch for everyday convenience.
• App Control: Bluetooth app lets an administrator add or delete users, share E-keys and view an access log for simple management.
• Remote Unlock Option: Connect a separately sold gateway to enable remote unlock and voice control through the Smart Life skill for Alexa or Google Home.
• Three Lock Modes: Auto lock, passage mode and privacy mode are available and switched from the interior knob for flexible use.
• Rechargeable Battery: Built-in battery charges in about 3 hours and claims long life with a low battery warning for predictable upkeep.

Who It's For

This smart door knob is ideal for people upgrading interior doors in apartments, bedrooms, or small offices who want a tidy, keyless experience and the ability to manage up to 50 users from an app. It fits users who value biometric convenience over commercial grade weatherproofing or exterior security.

Those who need a fully networked smart lock without buying an additional gateway, or who require robust outdoor durability, should look elsewhere; Bluetooth connectivity is reported as mixed by some users and the product is intended for indoor use only.
