Mustangs were the worst for losing key programming
To this day, I will not program keys to an older Mustang with PATS without sitting in the dealer parking lot
Never actually had any issues, just the stories I hear and the trouble I've seen, makes me do that
I'd call a locksmith if you don't have access to a NGS or don't want to mess with Forscan

Okay, code test and pinpoint tests are next then
Seeing as it just happened all at once leads me to think of a wiring concern
Hopefully a code test will narrow it down some
If we lived close to one another, I'd like to see what my NGS has to say about it

Maybe that is what's wrong with it
Lack of communication with the PATS module
A 03 Mustang service manual and a PCED would come in handy
