Why Switch to a Fingerprint Padlock?
Traditional padlocks force a choice between carrying a key or remembering a combination — and both can fail you. A fingerprint padlock opens with your fingertip: nothing to carry, nothing to memorize. The SK-U12 smart fingerprint padlock holds up to 20 fingerprints in an IP67 waterproof zinc alloy body, ready for luggage, lockers, gates and cabinets.
One Touch, Instant Access
Register a finger once and the lock opens on touch, with no key to lose and no code to forget. With 20 fingerprint slots, you can add family members, staff or teammates — and remove them anytime by re-enrolling the lock.
Built for Outdoor and Travel Use
- IP67 waterproof – works in rain, dust and splashes without issue.
- Zinc alloy + stainless steel – corrosion-resistant and tough.
- 50,000-hour mechanical life – built for years of daily use.
Power That Lasts
The SK-U12 runs on two CR2032 batteries with up to 6 months of standby, and a USB-C port lets you top up conveniently. When the cells finally run low, the tool-free battery cover makes replacement a 30-second job — no soldering, no technician.
Where a Fingerprint Padlock Helps Most
- Luggage and backpacks – TSA-style convenience without keys while traveling.
- Gym and school lockers – quick fingertip access during busy days.
- Storage cabinets and toolboxes – keep tools and valuables secure on site.
- Jewelry and display cases – protect high-value items from staff and visitors.
- Outdoor gates and sheds – weatherproof security that never needs a key.
Tips Before You Buy
- Enroll two fingers (e.g. both thumbs) so a minor injury never locks you out.
- Keep the battery level above 20% when using the lock in remote locations.
- Choose a padlock with a hardened shackle for high-risk outdoor use.
