Garage door remote control: I press the key to open the small lock. After the door is opened, it can't be closed. Is it unlocked? You need to check the code again. How do you check the code?

Analysis:

1. You pressed the lock key to prevent the door from running due to misoperation of the remote control. The solution is to press this button again to unlock, and the remote controller can be used normally.

2. How to check the code:

There is a password key on the nose. Hold it down until the indicator light stays on. Press the code key on the remote control continuously until the indicator light on the nose flashes and goes out. The code has been aligned successfully.

I hope this helps.
