Why can’t the door lock recognize my fingerprint well or it failed to unlock with the App?

When recording fingerprints, please place your clean and dry finger at different angles and positions to ensure that a larger area is scanned. The old and children may not use their fingerprints effectively, so keep fingers clean before unlocking.

After installing the new lock, what should I do to pair and set it up?

The smart knob is controlled by the Lockin Home app. Make sure Bluetooth and Location are enabled. After authorization, touch the fingerprint sensor to wake the lock. Only one user can connect at a time.
