97 Grand Am ignition

Is the car standard or automatic? If standard, is their a button on the steering column near the ignition switch? Automatic, try turning the wheel left and right while trying to turn the key back. If that doesn't work, while the engine is off, try shifting the shift lever back and forth while tryng to turn the key back.

There's probably a problem with the device on the shifter which allows you to remove the key. It may be a cable or electrical switch.

There is an electrical solenoid on the shifter of the automatic that controls the release of the key from the cylinder. If it is the problem, you will have to replace the whole shifter because the solenoid is not replacable.
