My 82 300 Turbo D startend and ran flawlessly on my way to work today (6/23). It was parked all day long. However, when I went to start it up, to myd consternation, the key would not turn in the ignition an the steering wheel is locked up. Has anyone experienced this problem and could you please advise. Is it the key, the cylinder or something else? Would my wife's spare key work? Would appreciate response before Monday morning so I can decide best course of action. Thanks in advance.
