Fingerprint Door Lock 5-in-1 Smart Door Knob - Fast Biometric Access

In this review of the Fingerprint Door Lock, the bottom line is that it suits homeowners and renters who want stronger interior security without complex installation. The lock combines a high-resolution fingerprint sensor with multiple backup entry methods, making it ideal for bedrooms, offices, and apartments where quick, keyless access matters most. The review finds the standout reason to buy is the fast and accurate fingerprint recognition, which unlocks in about 0.2 seconds and reduces the friction of daily entry compared with traditional keys.

Key Features

• 5-in-1 Access: Offers fingerprint, mobile app control, keypad codes, IC cards, and mechanical keys so users always have a reliable way in.
• High-resolution Sensor: A 508 DPI fingerprint module with 160 x 160 effective pixels delivers a recognition rate above 99% and very quick unlocking.
• Remote Control Capability: When paired with the optional BIWIBON Gateway, the lock supports remote locking, unlocking, and issuance of time-limited codes.
• Easy Installation: Designed for most American wooden doors and installs with a screwdriver without extra drilling or specialized tools.
• Anti-peep Keypad: The touchscreen keypad accepts extra random digits before or after the real code to protect the PIN from onlookers.
• Passage Mode: Keeps the door unlocked when needed for gatherings or frequent access without removing security features.

Who It's For

This product is for people who want a modern interior door solution that blends biometric security with several convenient backups. It works well in apartments, bedrooms, home offices, and other interior doors where users want fast, keyless entry and occasional remote management when using the gateway.

Those who should look elsewhere include buyers needing heavy-duty exterior weatherproof locks or users who require an integrated hub included out of the box, since the remote gateway is an optional purchase and the unit is intended primarily for interior wooden doors.

Frequently Asked Questions

What is the Type-C port for?
The Type-C port is for emergency power only and should not be used for regular charging to avoid damaging internal components.

What batteries does the lock use?
The lock uses four AAA alkaline batteries; rechargeable cells can be used but should not be charged through the Type-C port.

Why can anyone unlock it at first?
The lock is initially set to accept any fingerprint until the administrator registers an admin fingerprint, so setting an admin print after installation is important for security.
