Fingerprint Door Lock 5-in-1 Door Knob - Keyless Security for Home

Our review of the Fingerprint Door Lock 5 in 1 door knob finds it best suited for people who want a compact, interior door upgrade that replaces a standard knob with multiple modern entry options. The biggest reason to consider it is the combination of fast biometric entry and flexible backup methods: a high-resolution fingerprint sensor, keypad codes, IC cards, app control when paired with the optional gateway, and traditional mechanical keys. Installation is straightforward for most wooden doors, so it appeals to DIYers who want more convenience without rewiring.

Key Features

• 5-in-1 access: Choose between fingerprint, mobile app control (with optional gateway), entry codes, IC cards, or mechanical keys for convenient redundancy.
• High-precision fingerprint sensor: The enhanced 508 DPI module with 160 x 160 effective pixels promises fast recognition in about 0.2 seconds for everyday quick entry.
• Remote control capability: When paired with the BIWIBON Gateway (sold separately), users can lock or unlock remotely and issue time-limited codes for guests.
• Easy installation: Designed to replace most American wooden door knobs without extra drilling or special tools, making setup possible with a basic screwdriver.
• Anti-peeping keypad: The touchscreen keypad accepts random digits before or after the real code to protect your PIN from onlookers.
• Passage Mode: Keeps the door unlocked when desired for gatherings or frequent traffic without disabling other security features.

Who It's For

The Fingerprint Door Lock fits homeowners and apartment dwellers who want a modern interior door solution for bedrooms, offices, or secondary entrances where a keyed deadbolt is not required. It appeals to those who value quick biometric entry and multiple backup options so they are never locked out if one method fails.

It is less suitable for exterior doors that require heavy-duty weatherproofing or commercial locations needing higher grade cylinders; buyers who require a fully networked lock without an extra gateway should also look elsewhere for built-in cloud connectivity.
