(In 2008, the Falcon FG was released. However, Ford continued to make the BF-series station wagon until September 2010 as the BFIII, whereas the sedan stopped at BFII before changing to the FG.)
This car refused to start this afternoon. A mechanic did some diagnosis and concluded that there was a problem with the immobiliser.
I figured that I’d have a go at resetting the keys with FORScan.
I wasn’t successful.
A message appeared: “Timed access PATS requires the diagnostic tester to enter into a runtime delay before Security Access is allowed. Continue anyway?”
I clicked on ok to continue.

I would then get an error message: Service procedure has been interrupted, please contact developers.”
I tried this a few times, but got the same error message each time.

I then tried to do a PCM reset. This gave the error message: “Service procedure is not supported, please contact developers.”

I had the extended licence in place:

And that was it. The car has been left, parked outside the workshop for the night.
Looks like I’ve stuffed it up, and will now need to pay an auto-electrician to reset the keys.
Both of the keys that I used have been used to start the car previously.
