2005 C2 Key Problem
 

I have two keys for my 2005 Porsche 911 C2. Both are memory programmed exactly the same.

Key #1 causes a strange problem. When I unlock the car remotely, the driver's side mirror moves down and in so that my view from the driver's seat is of the left side door. It's easily reset with the adjustment switch, but having to adjust the mirror every time I unlock the car gets old. Resetting the memory afterward does not prevent the problem from re-occurring on the next unlock.

Key #2 does not cause the mirror to loose its position.

Does key #1 need to be professionally reprogrammed, or does it need to be replaced?
