Thanks for the info
Is the shifter stuck in park or another gear?
So if I understand you correctly.....you can insert the key but cannot turn it and it is in the off position.....the steering wheel turns freely from side to side and the gear shift is stuck in Park and will not move?
I was wanting to verify the shifter was in Park
I am attaching the info on ignition switch lock cylinder replacement. In it talks about if you cannot rotate the key.........I put those directions at the end.
It appears the locking mechanism is on the ignition switch lock cylinder.
