I had a look at my battery inside the key fob this morning cause i was about to go to work at 5.30am n it wouldnt open the car. My mrs is off work sick so i took her car to work but if she was going to work i wud of been fooked. I would of had to open the car door and set the alarm off to see if the alarm would sort itself out. I think it might be time for an auto electrician.
