I didn't even think about the key positioning. My horn, sunroof, garage door opener and auto door locks stopped working when you start the car. I read this post and put the panic button at 6'oclock and everything worked. I also tried the spare key and it did the same thing (panic button at 12'oclock horn etc. not working but panic at 6 things worked fine. With the key chain hanging it's not the natural feel to put the key in with the panic @ 12'oclock. Does this have anything to do with the ignition switch?
