Why did the car key fail?

1. It may be that the remote control key is out of power and the remote control key cannot transmit signals, and the receiving module cannot receive the signal, so the remote control fails. It can be solved by replacing the battery of the remote control key.

2. After replacing the battery of the remote control key, it still cannot be used. At this time, you need to check whether the remote control key itself is malfunctioning, or whether the remote control receiving module malfunctions and the remote control fails.

3. It may be the place where the vehicle is parked, and there is a strong signal interference that causes the remote control to fail. You can try it in another parking place.
