If you can't find the smart lock when pairing it with the APP, please check if you changed the master code on the keypad before pairing. If so, you need to reset the smart lock with the reset tool before pairing.

There are two possible situations to consider:

1.If the app displays "Unable to find locks. Please restart your phone's Bluetooth and try again," please restart your phone's Bluetooth, then activate the smart lock keypad and try again.

2.If you can find the smart lock, but it appears gray and shows "The lock is not in setting mode," please reset the smart lock with the reset tool, turn on your phone Bluetooth, and stand within 2 meters of the lock. Then activate the keypad to see if you can find the lock.

If you still can't solve the problem, please contact our customer service at support@teeho.com

 or (833)878-3346.
