Password Padlock Guide: Keyless Digital Lock with Tuya App for Lockers and Gates

Password Padlocks: No Keys, No Fingerprint Readers, Just Codes

For shared spaces like gyms, warehouses and schools, a password padlock is often the most practical choice: anyone can be issued a code, and codes can be changed in seconds. The SK-U701 smart password padlock adds Tuya App control and temporary codes to a durable zinc alloy body.

Why Choose a Code Padlock?

  • No keys to lose – access lives in a 6-8 digit code.
  • Shared access made easy – up to 100 password slots for different users.
  • Instant changes – reset codes when staff or tenants change.
  • Works in any weather – IPX5 protection against rain and splashes.

Security Features That Matter

  • Anti-peep code – type random digits around your real code so onlookers cannot learn it.
  • C-grade cylinder core – high security against picking and forced entry.
  • Zinc alloy body – corrosion-resistant and tough for daily use.
  • Low battery alert – clear warning before the 2×CR2032 cells run out.

Tuya App Control and Temporary Codes

Through the Tuya App, you can unlock the padlock from your phone and manage codes with cloud storage. Temporary passwords are ideal for visitors, contractors and guests — issue a time-limited code instead of handing over a key, and revoke it when the visit ends.

Where a Password Padlock Works Best

  • Warehouse and tool storage – code access for shift workers.
  • Gym and school lockers – individual codes for members and students.
  • Gates and fences – weatherproof keyless entry outdoors.
  • Luggage and equipment cases – codes instead of keys on the move.
