Once paired, you can register fingerprints. The padlock supports up to 20 different fingerprints, including 2 administrator fingerprints. Follow these steps:
- In the app, navigate to the 'Add Fingerprint' section.
- Place your finger on the padlock's fingerprint sensor.
- Lift and reposition your finger as instructed by the app to capture different angles of your fingerprint. This typically involves several readings.
- Ensure your fingers are clean and dry for optimal recognition.
- Once all readings are complete, your fingerprint will be stored and ready for use.
Operating Instructions

To unlock the padlock using your registered fingerprint, simply place your finger on the fingerprint sensor. The padlock will unlock in approximately 0.1 seconds if the fingerprint is recognized.
2. App Unlock
You can also unlock the padlock via the eSmartLock app. Open the app, ensure your device is connected to the padlock via Bluetooth, and tap the 'Unlock' button. The app allows administrators to authorize family, friends, or colleagues to unlock the padlock, with options to set unlock periods and schedules.

Troubleshooting
- App Not Working / App Hangs: If the eSmartLock app experiences issues or hangs upon opening, try reinstalling the app. Ensure your device's operating system is up to date and that the app has necessary system resource permissions.
- Fingerprint Recognition Issues (Wet Fingers): The padlock's fingerprint sensor may not function optimally with wet or pruned fingers (e.g., after swimming or showering). Ensure your fingers are clean and dry before attempting to unlock.
- Trouble Storing Fingerprints: If the app and lock have difficulty storing new fingerprints, try renaming the user name for the prints within the app. Sometimes, a simple change in the user profile name can resolve the final step of the registration process.
