2001 Malibu ignition locked

Key goes in and out ok but will not turn to start. I’ve seen where this model has a lot of ignition problems but this seems like a safety lock is not releasing. I can’t get it out of Park if the key won’t turn and I’ve wiggled the wheel and even rocked the car back and forth while trying to turn the key. Is the problem in the key cylinder or switch or is there saftey lock to check and where is it? Thanks Mike
