The Keypad Padlock: Codes Without the App
Not every lock needs a smartphone. For gyms, schools, warehouses and outdoor gates, the SK-U704 keypad padlock offers what many managers actually want: a simple 3-8 digit code, no app to install, no pairing to troubleshoot, and a mechanical key as a final backup.
Why Choose a Keypad Combination Lock
- No keys to carry – codes work for everyone, from staff to students.
- No app needed – works anywhere, even without a phone or signal.
- Easy for everyone – simple keypad entry is ideal for elderly users and children.
- Change codes in seconds – reset access when people leave.
10 Password Groups, Under 0.5 Seconds
The SK-U704 stores up to 10 password groups, so different users can each have their own code — ideal for shared lockers and staff areas. Recognition takes under half a second, making entry as fast as a mechanical key.
When the Battery Runs Out, the Key Steps In
Two CR2032 cells power the lock for 9-12 months. When they finally run out, the included mechanical key opens the lock — safe and practical, with no dead-lock situation and no special tools required.
Built for Real-World Use
- IP67 waterproof – fully protected against rain and dust.
- Zinc alloy body – durable and corrosion-resistant.
- C-grade cylinder core – high security against picking.
Where the SK-U704 Works Best
From dormitory cabinets and gym lockers to fence gates, warehouses and truck compartment doors, the SK-U704 handles demanding outdoor and shared-access environments.
