What I do in that case, I go to the trunk, open it manually, disconnect the negative terminal, alarm goes off, reconnect negative cable, then key fob works just fine and i'm able to unlock the car.

How long do you leave the neg batt cable off for to restart? I don't have an alarm on my car. I just need a backup plan for if this fails when im out and about. I heard you can use the key in the door and hold it in the unlock position and it rolls down the windows and puts the roof down, is this true?
