My key got sticky around 30K miles. The dealer had another Crossfire with the same problem and switched everything out but the problem was still there. By the time they got to my car they knew what was causing the problem. It was the steering wheel lock mechanism. DON'T LET THE DEALER CHANGE THE TUMBER, LOCK MECHANISM....etc. It is a waste of money. Your problem is the lock mechanism. There is a pin causing the problem. Check the forum... someone did a writeup on it.
