2002 Mercedes-Benz S430 Q&A
2002 Mercedes-Benz S430 Question: Why wont my key turn in the ignition switch, I am unable to start the car.
Sounds like a mechanical failure of the ignition switch. Are you sure the steering "lock" is not applied, try turning the steering wheel side to side as you rotate the key, perhaps try lock ease or lock lubricant. - patrick mannion
