So i have an issue with my ignition cylinder. I will drive the car, put it in park and the turn the engine to off but on occasion the key wont turn all the way and i have to start the car again and shift through the gear to release the key? Any idea what could cause this? This only happens occasionally and that makes me think a switch or sensor is starting to see the light at the end of the tunnel. Hopefully this is a common issue with an easy fix. Let me know what your thoughts are. At the moment the key is in the ignition with the car locked outside. I tried to get the key out for about ten minutes before i gave up. It seems to be getting much worse and more frequent over the last few days. Please help me out here because im not very comfortable leaving the key in the car overnight. Thanks
