Is the remote control key failure the cause of the key shell?

The first situation is that the battery is dead or the battery is in poor contact;
The second situation is the failure of the time control module in the remote key shell, which will also cause the remote control to not work;
The third situation is because the antenna of the remote control transmitter on the car is aging, etc., which can also cause this situation. In this case, you can go to the repair station to check and repair it.
