came out of work earlier to the S3, unlocked it, pulled the door it wouldnt open so i thought it was iced shut, so pulled the boot which was fine and opened the door from the inside which was easy, neways started de icing the windows with a CD case of course and realised i still couldnt get in, and then i locked the car with the door open and then unlocked it and it didnt unlock the doors, never had a problem like this before today when it was icey
