Our take on the BIWIBON Fingerprint Door Lock

The BIWIBON Fingerprint Door Lock (model BCA-02) is a metal smart knob that opens by fingerprint, keypad code, IC card, app, or backup key. It stores up to 100 fingerprints, 100 codes and 100 cards, and runs on four AAA batteries. At $37.99 at Amazon as of November 4, 2026, it sits at the low end of what a biometric knob typically costs, so it is a cheap way to try keyless entry on an interior door.
