Key Gets Stuck In The Ignition

[Sundown94]

Hey Everyone! Just today I started having a problem that I have seen several other people have up here on the forums. My deal is that when I shut off the truck, the key won't turn all the way back and is stuck in the ignition. However, I can press down on the brake pedal, move the shifter back and forth AS FAR AS POSSIBLE (making sure to end with it in Park), and -- after a few tries -- the key finally releases. I can actually hear the cylinder lock electronically disingage just before the key finally comes out, so I know the ignition lock does not need WD40 or graphite powder. The questions I have are: what could be causing this problem to happen all of the sudden today and do it intermittently? Why does it suddenly release my key after moving the shifter a few times? Is the problem in the ignition, the wiring, or the switch in the shifter? What can I check or do to diagnose the problem? I hate to remove my cup holder (around the shifter) again unless I absolutely have to because the damn clips that hold it in are practically destroyed from a previous removal...they are the worst design for holding the cup holder in place but that is a topic for another thread.
