I’ve had my shifter replaced once under warranty for this problem and it has started happening again. There are several potential workarounds and fixes, but I thought this was the best explanation and potential fix for the issue:

For now, I’ve been doing the following if the key gets stuck:
1) Turn key back to “on” position (don’t need to start the car)
2) Place foot on brake (car can stay in Park)
3) Squeeze the silver shift release button at the top of the shifter several times rapidly
4) Key should be able to be released at this point
If this ever stops working, I will probably try the procedure in the video.
