I have a 2008 envoy, I turned off the car and the key was caught in the ignition, went to turn it back on and the car was completely dead, no power to anything,
so I:
1. checked the battery and it was dead and so I replaced it, the car was energized as normal, I could start the car but the gear shifter was stuck (locked, including press button) in the park position, also when turning it off the key still wouldn't come out of the ignition.
2. I've attempted to rock the car to move it out of park, to no success
3. looked in the forums and saw that when you put your foot on the brakes you should hear two solenoid clicks, 1 near the brake and 1 near the centre console passenger side. I could hear the one on the passenger side, I could not hear the one in the front. I also happen to have a 2003 envoy and on that envoy just when you turn on the car and press the brake you hear 2 solenoid clicks. So there might be something going on there.
4. tried manually pressing the solenoid button that you can get at by pulling the plastic on the passenger side of the console and shoving your hand up there - no difference
5. changed the fuses referenced in this link:

fuses 25 and 27 so they arent the problem.
6. based on some other advice I've changed the ignition switch and that didn't solve the problem
So basically I'm stuck with a car that turns on, and once turned on the gear shift will not move out of park, when I turn the car off the key won't come out without pressing the release button that is inside the steering wheel column.
What would be the next things I could check? Is there any chance this has something to do with the car security system?
