Forscan and Pats Use

[imp]

Would anyone be good enough to "school" this old guy more on how to get & use Forscan to manipulate non-working keys? History: DTCs pointed to bad PCM, bought a rebuild, came with two keys. Installed PCM, started engine fine with one key, other did not work. Failed to follow written instructions, I know.

Put ORIGINAL PCM back, OEM from the Ex, started fine, assumed other key must work just like always before, IT DID NOT! Now, I have 2 working PCMs and only one key which works with each. Why did my original PCM which came with the car, and it's 2 keys which worked fine before it's removal, NOT allow both keys to work after being reinstalled?? imp

There is a sticky that I started on forscan. http://www.explorerforum.com/forums/index.php?threads/pats-key-sucsess-thanks-forscan.432028/ Read this and I think this post will answer all of your questions.

Thanks much! An old and long read, but I think, that's an iffy, think, with my limited ability and exposure to the lingo involved, that I might be able to get through it. The Forscan site is impossibly complex, for me to follow. imp
