Here's the problem: Came home, parked the car in the driveway (slight incline), came back out about an hour later and found the key would not turn! Tried turning the wheel left and right to the stops, jiggled the key while doing so, rocked the car while jiggling and turning the wheel and was just short of getting a screwdriver! I have a 1991, 190E, 2.3. Is there anyway to unlock the wheel without tearing the dash apart? How hard and where can I find the proceedures for replacing the ignition lock on this model car? Any help will be greatly appriciated!!
