What if the eight-door remote controller can't clear the code?

The eight-door remote controller cannot clear the code, so you can try the following steps:

1. Prepare the controller of the shutter door and the remote control key to be checked.

2. Find a small hole in the controller and shine it with a flashlight. You can see there is a white button inside.

Press this white button, you can hear a drip, and at the same time you can see that the red light of the controller is on.

4. Take out the remote control key prepared before, and you can see there is a black key on the back. This black keys is the so-called code matching key.

Press this code key, you can hear a drop and see the red light on the remote control.

6. Wait a few seconds and see that the red light on the remote control goes out, and at the same time, the red light on the controller goes out. At this point, the remote controller has been paired and cleared.
