Having problems with your Pontiac Grand Prix ?
My car sometimes won't let go of my key when I shut it off. Dealer says it has to do with the theft deterrent module, but all the stuff I've read about it on the internet suggests that the theft deterrent module is a problem when the car won't start or won't stay running, not that the key won't come out when the car is in Park. Help! What part should the dealer get?
This is probably the ignition lock cylinder worn out or getting old. The TDM is most likely not locking the key in, but new cars are pretty tied into themselves. For now, just try leaving the key in. Use another one for the doors. Some cars have a small hole under the steering wheel/column that you can stick a pen or something in to release your key. Maybe just be ready for something else breaks, then you'll know what is wrong.
