4. Setup
4.1 Initial Fingerprint Registration (Administrator)
Upon first use, the padlock is in default status, meaning any fingerprint can unlock it. You must register the first two fingerprints as administrators. These first two fingerprints are crucial for managing additional users and resetting the device.
- Press and hold your finger on the fingerprint sensor until the blue light illuminates. Release your finger.
- The green light will illuminate. Place your finger on the sensor repeatedly from various angles until the green light turns off. This completes the registration of the first administrator fingerprint.
- While the green light is still illuminated, use a different finger and repeat step 2. This registers the second administrator fingerprint.
After completing these 3 steps, the first two fingerprints are successfully set as administrators. The padlock will now only unlock with these registered fingerprints.

4.2 Registering Additional Fingerprints (Users 3-10)
To add more user fingerprints (up to a total of 10), an administrator fingerprint is required.
- Press and hold an administrator finger on the sensor until the blue light illuminates. Release the finger.
- The green light will illuminate. Have the new user place their finger on the sensor repeatedly from various angles until the green light turns off. This registers the new user's fingerprint.
Repeat these steps for each additional user, up to a maximum of 10 fingerprints in total.
4.3 Deleting All Fingerprints (Factory Reset)
To delete all registered fingerprints and restore the padlock to its factory default state (any fingerprint can unlock), follow these steps:
- Place an administrator finger on the sensor and hold it. The blue light will illuminate, then turn red. Continue holding.
- After the red light illuminates, the green light will flash once. Release your finger immediately after the green light flashes.
All fingerprints are now deleted, and the lock is reset to its default state. Any fingerprint can now unlock the device until new administrator fingerprints are registered.
