Fingerprint Door Lock 5-in-1 Smart Door Knob - Keyless Home Entry

In this review of the Fingerprint Door Lock 5-in-1 smart door knob, the bottom line is simple: this is a solid option for anyone who wants a versatile, keyless interior lock with multiple modern access methods. It shines for users who value fast biometric access and simple retrofit installation into standard wooden doors. The review focuses on real-world use: the fingerprint sensor is very fast when it works, installation is straightforward, and the lock supports fingerprints, a mobile app (with a separate gateway), IC cards, PIN codes, and mechanical backup keys.

Key Features

• 5-in-1 access: Offers fingerprint, mobile app control (with gateway), IC card, PIN code and backup mechanical keys for flexible entry options.
• High-resolution sensor: Uses a 508 DPI, 160 x 160 sensor that claims fast recognition and secure biometric identification for frequent use.
• Quick recognition: The fingerprint module reports a recognition time of about 0.2 seconds, which speeds entry compared with digging for keys.
• Remote control ready: When paired with the optional BIWIBON Gateway, the lock supports remote unlocking, issuing time-limited codes and viewing access records.
• Easy retrofit installation: Installs on most American wooden doors using only a screwdriver, with no extra drilling or special tools required.
• Anti-peeping keypad: The touchscreen keypad accepts extra random digits around the real code to protect your PIN from onlookers.

Who It's For

This smart door knob is best for homeowners and renters who want to replace an interior knob with a keyless option that keeps a mechanical backup. It suits bedroom, office or apartment doors where fast biometric access and occasional remote control (with an added gateway) are useful. The lock's design and finish make it appealing where appearance matters as well.

People who need a weatherproof outdoor lock, multi-door commercial access systems, or a product with guaranteed flawless fingerprint performance in every environment should look elsewhere; some users have reported intermittent fingerprint reliability and occasional random faults, so those requiring absolute consistency in harsh conditions may prefer a different class of lock.
