Given the amount that your parts guys DOESN'T know about the PATS antitheft
system, I am surprised that they would allow him to talk to customers....
Are you sure you weren't dealing with the janitor?
Using the new key at the wrong time will disrupt the programming sequence...
nothing more. The process is so easy that anyone, (well, anyone except your
parts guy) should have no problems completing the routine. Read the process
several times and have the owners guide handy and open - just in case. Many
of the steps must be completed within a finite time frame and may not leave
enough time for lengthy pauses while referring to the documentation....
again, a mis-step will be a minor inconvenience but can be unnerving enough
to frustrate or scare the beginner.
If something does, indeed, go wrong (and I haven't seen anyone that can
screw up the process - though I have seen some that can't complete the
process) - programmoing 3 keys from scratch will take about 20 minutes to
1/2 hour - beginning to end. Most dealers will charge 1 hour labour (this is
to offset the cost of the diagnostic tool, it's software subscriptions and
(hopefully) some basic training in scan tool usage). At least 10 minutes of
the programming process is taken up with waiting for "Security System
Access" to be granted.
Try to avoid that partsman in future.... he has no good advice.
FWIW.... I have been a licenced journeyman automotive tech for about 33
years and have been involved in the trade for almost 40. I am a Ford Master
