Fingerprint Door Lock Smart Door Knob - Biometric 5-in-1 Security

Our review of the Foxgard Smart Fingerprint Door Lock finds it best suited for homeowners or renters who want keyless convenience and multiple backup entry methods for interior doors. The single biggest reason to buy is the combination of biometric access plus app control, which makes daily entry fast while giving owners remote management and access logs when paired with a gateway. Installation is straightforward for standard bedroom or office doors and the lock's modern round silver finish fits most interiors.

Key Features

• 5-in-1 unlocking: Fingerprint, 4 IC cards, keypad code, Tuya Smart App, and 2 mechanical keys provide flexible access options for family and guests.
• Biometric speed: The fingerprint sensor allows near-instant entry with a single touch, eliminating fumbling for keys.
• Remote and voice control: When used with the Foxgard Gateway, the lock supports voice assistants and remote management through the Tuya Smart App.
• User capacity: The lock stores up to 100 fingerprints, 100 cards, and 100 codes, making it suitable for larger households or small offices.
• Emergency power and battery life: Powered by 4 AAA batteries with low battery alerts and a Type-C emergency power port for a temporary external power source.

Who It's For

This smart door knob is ideal for people who want a modern, keyless solution for interior doors such as bedrooms, home offices, or small business rooms and who value fingerprint convenience paired with app features like temporary codes and access logs. It suits users who appreciate a clean install without extra drilling and compatibility with left and right-handed doors.

Those who need heavy-duty exterior weatherproofing, commercial-grade deadbolt security, or fully integrated enterprise access control should look elsewhere, as this product is designed primarily for interior convenience and residential use.
