On my Chrysler 5th Ave it has a factory alarm that normaly you would unlock the passenger door with a key to disable it. For some reason this does not wok anymore and I wish to disable the whole alarm because now we can NOT turn it off. It has disabled starting of the car and this is my only car I own. Has anyone else had this problem or know how to resolve it? I have tried to unhook the batter over night this stops the lights from flashing but the car still does not start. It simpley starts and kills within a second.
