U-Shaped Padlock: 5-in-1 Keyless Security for Glass Doors
Glass shop doors and office entrances need security that doesn’t rely on clunky padlocks. The SK-U9 U-shaped padlock is a 5-in-1 smart lock — fingerprint, password, RFID/NFC card, mechanical key and Tuya App — built around a C-grade cylinder and a waterproof U-shape body.
Five Ways In, Zero Compromise
Unlock with one touch of your fingerprint, a PIN, an RFID/NFC card, the mechanical key, or your phone through the Tuya App. With 32 fingerprint slots and 1000 password/card entries, the SK-U9 suits teams, stores and shared entrances.
Anti-Peeping Scramble Password
Worried someone is watching you type? The scramble password feature lets you enter random digits before and after your real code — your PIN stays hidden while access stays instant.
Built for Glass Doors and Beyond
The U-shape body mounts easily on glass doors with handles, aluminum frames and wooden doors. Waterproof construction keeps it reliable outdoors, and three AAA batteries deliver up to 2000 unlocks before a change.
Where the SK-U9 Works Best
- Glass shop and office doors – secure after-hours access.
- Aluminum frame doors – clean, keyless retrofit.
- Bicycle and storage – sturdy U-shape locking.
- Shared equipment rooms – issue codes per user.
