The key removal inhibit solenoid is energized anytime the lever is NOT in PARK. FYI, if F34 were to blow, the solenoid would be de-energized and the key would be removable at any time.
I guess I'll pull the cylinder out and check it. I looked the TSB up (it's not in the archives, also FYI) that was mentioned and it recommends replacement of the cylinder. I checked with a dealer parts dept who said I need the complete lock set (doors, trucnk, and ignition) since I have a PATS system.
I'll see what the inspection reveals.
Thanks,
Steve
