Hi need some help my cl is not working from remote works fine from key in door don't know where to start any help much appreciated oh its a 5g thanks

I would check the battery if you have not already done so. Also check the connections for the battery. Press the button and listen for a micro switch click. If it doesn't click then the button could have broken from the board. If the problem is not with the switch i wouldn't know where to start
