Question about 2001 Cadillac DeVille

2 Answers

My Deville runs great and has only 70,000 original miles. I parked it tonight. When I went to re-start it, my key would not turn the ignition switch. The car is in park. I have tried putting foot on brake while turning key, have power all over, remote is opening and closing doors, nothing else is wrong. The steering wheel is acting like it is locked in place. This has never happened before. Is there some type of release somewhere or what can it be? Thanks.

GM uses a Passkey system - your ignition system recognizes any key that is specially coded to your vehicle. If the key you are using is not the key for your vehicle, or your key is damaged, or the vehicle Passkey system is not working properly, the key will not turn. You should have at least three keys for this vehicle - two regular keys and a valet one. If all of them won't work, the problem is in the steering column. If you only have one key, take it and the vin number from your car to a GM dealer and get them to cut a new one and try that. If that doesn't work, you may have to get the car to a dealer for repair. You can also check for an ignition switch recall for your car, but that's a long shot.

    Here's another thought - your car theft deterent system may have locked you out. If the security light on the dash is on steady, a GM dealer may need to to properly diagnose the problem and reset the system for you.

This happens occasionally on my cars... firmly jiggle the steering wheel as your turning the key... this should "unhook " it.

Won't start

You would need to check for voltage at the starter, the neutral safety switch, and the key switch. Sounds like the key switch may be failing.
