BioLock Fingerprint Padlock

No Key. No Code. Just Your Fingerprint.

This KERUI fingerprint padlock unlocks in under a second with a single touch — no key to lose, no combination to forget. Store up to 10 fingerprints and share access with family or colleagues without handing over a key.

One Lock. Every Door.

Compact enough to fit in a jacket pocket, tough enough for outdoor use. Use it on doors, cabinets, bikes, backpacks, storage lockers, and more — wherever a standard padlock would go, this one goes too.

Six Months on a Single Charge.

The built-in 3.7V lithium battery lasts approximately six months on standby. When the charge drops below 3.5V, the red LED flashes for 15 seconds as a low battery reminder — and repeats once per hour until you recharge via USB-C.
