The central locking on my car has stopped working off the key fob, but still works when i use it in the door. i've tried getting a new key reprogramed but that didn't work. I've had an auto electrician look at it but he din't have a clue, took it to my bmw garage and they said it might be something in the rear spoiler as its a touring and they fill up with water, but theres no way i'm paying there prices for them to tell me it just is that. Anyone ideas???
