I have a 06 Freestar that I want to take a used junkyard 104 pin PCM from an 07 Freestar and program the vehicles keys to it , so the customer can have a ready to go spare PCM to have when the original one bites the bullet. ( PCM has PATS communication issues in cold weather along with moisture condensate issues)
I'm wondering if I'm unsuccessful getting the junkyard pcm and keys programmed to it using a DS708 , if I then put the original PCM back into the vehicle will the original pcm and keys still be recognized and van start ?
