Select a product to estimate shipping.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.
If the batteries die, how can I open the door?
The smart door knob built-in rechargeable battery. You can use an emergency power supply to charge the smart door knob through a USB A+Type C port or use the backup key to open the door.
Why is my Smart Lock low-powered?
Charge the lock for 3-4 hours before installing. When the low battery warning occurs (fingerprint unlocked first green light then flashing red light), indicating the need for charging.
