Well, I decided to go out to the garage and try the locks again after the car set approximately 1 1/2 hours. It now works the same as it always has. I can lock and unlock the car from the driver's side door, but the passenger side door lock will not lock the door. It will only turn to the left, but not turn to the right to unlock. This has been the way the system has always worked from the time I purchased it. I am puzzled with how this has happened today...could it be gremlins at work?? However, after owning Mercedes' I am convinced, that you need to be prepared for anything can happen!!
