The keys are stuck in the ignition in this vehicle, even when the car is in park. What can be done to fix this, so the keys can come out again? Thanks!
As suggested by jzd in a comment, try removing the key when in Neutral rather than Park.
If trying while in Park, try to ensure you are in Park and the car knows that it's in Park. Does anything else usually happen when Park is engaged? A dashlight or something else to indicate that the car knows it is in Park.
Another thing to try is giving the steering wheel a bit of jiggle, sometimes the steering lock can 'jam' keys, although usually this is more of a problem when inserting keys and starting rather then removing.
