Bluetooth Fingerprint Padlock Guide: App-Managed Keyless Lock for Gates and Lockers

One Touch, No Keys: The Bluetooth Fingerprint Padlock

A fingerprint padlock replaces keys and combinations with your fingertip. The SK-U702 fingerprint padlock goes further with Tuya App support: enroll up to 20 fingerprints for one-touch entry, then manage access and opening records from your phone.

Fast, Reliable Fingerprint Entry

The sensor recognizes a registered finger in under 0.5 seconds. With 20 fingerprint slots, a family can each use a different finger, a team can share a toolbox lock, and a gym can assign lockers without issuing keys or codes.

App-Managed Access via Tuya

Through the Tuya App, you can unlock the padlock remotely and keep records in the cloud. This is especially useful when several people share one lock: enroll a new user from the app, or delete a user when they leave — no physical rekeying needed.

Built to Last

  • C-grade cylinder core – high security against picking and forced entry.
  • 304 stainless steel shackle – hardened steel resists cutting and prying.
  • Zinc alloy body – durable and corrosion-resistant.
  • Waterproof design – works outdoors in rain and dust.
  • 10-12 months standby – two CR2032 cells last for months.

Where the SK-U702 Fits

From gates and fences to school lockers, gym lockers, office lockers, toolboxes and sheds, the SK-U702 brings keyless convenience to everyday security. Its compact 88×46×22mm body suits standard lock holes on doors, cabinets and storage units.

Tips for Shared Lockers

  • Enroll two fingers per person in case of a minor injury.
  • Use the app to manage users instead of re-enrolling the whole lock.
  • Replace the CR2032 cells when the low-battery alert appears.
