Troubleshooting:

Installation:

If you are meeting the problems, please follow the Installation Guide to re-install the whole lock.

> Please check the depth of the frame's hole, it must be more than 1''. For the Latch/Lever/Handle lock, the frame's hole is usually less then 1'', please drill the hole.

> Loosen the screws on the Mounting Plate (Screws D) and the Deadbolt (Screws C). Over-tightening the screws during installation may result in a clicking noise coming from the lock, or even failure to operate with the App/Keypad/Fingerprint.

> Lefting 2 pieces of the tailpiece out of the mounting plate. If the tailpiece is too long, the motor is overload.

> Make sure the tailpiece is in the middle of the round hole. Otherwise, the tailpiece will rub the wall of the round hole, the motor works overload. Please loose two screws of the mounting plate, and adjust its position.

> Adjust the wire placement to avoid rubbing the tailpieces of the cylinder.

Calibrate the U-Bolt/U-Bolt Pro lock's direction.
