Man I'm glad you got it going. I don't know that I've ever heard of the PCM being locked like that where a KAM reset didn't fix it, I knew you were going the right steps. I wonder now if a battery disconnect may have help. Doesn't matter now, as long as you are running and have the only keys that will start the truck! What version of Ford module is on your Autel tool?, Guess I'll be pricing a CK-100 for backup.
Thanks for keeping us updated and letting us know you are fixed. I have several post in here that you never hear the results, Like watching a movie and missing the last scene. Bummer!
Ride on Man and hope your truck is fine.
Thanks
