I have experienced the dreaded frozen lock problem, but today something different happened and I was wondering if anyone had come across this before. I came home and locked the car on the fob as normal. Shortly after this, I went out, drove a short distance and again went to lock the car. Unfortunately this time, the locks bounced back up and this was accompanied by what I can only describe as the sound of an electric drill from the passenger door. The doors will lock on the key and the fob arms the alarm and when trying to open, the doors will only unlock with the key (once again accompanied by the drill sound) Any ideas?
