Is the vehicle in park? I ask because not being able to remove the key could be an adjustment issue. Also, do the brake lights work? Power to the interlock actuator is provided through the brake light switch, so that could be another possible issue.
Since you said it does the same thing, I need you to check fuse 29 in the underhood power distribution box.
If you look at pic 1 below, I highlighted the fuse I'm referring to. In addition to checking the fuse, make sure there is power to and from it. Here is a link that you may find helpful:
Also, pics 2 and 3 show the wiring schematic for the shift interlock.
Let me know what you find or if you have other questions.
See pics below.
