Reason 1: under normal circumstances, the failure of the remote control lock may be the cause of the car body or the remote control key itself. In the remote control key, the failure of the time control module and the aging of the antenna on the remote control emitter may cause the remote control to not work. This requires the owner to check out the problem in time to the 4S store or the professional maintenance office when the remote key is out of order and determine whether it is a mechanical problem. Reason two: because of the cold weather, some parts of the remote control are sticky, resulting in poor contact. Therefore, the car mainly safeguards the remote control key of the car, so as to avoid oil contamination.
