FORD 2002 Mustang v.1 - Manual (Page 101)

Key information
Your vehicle is supplied
with two coded keys.
Only a coded key will
start your vehicle.
Spare coded keys can
be purchased from
your dealership. Your
dealership can program your key or you can “do it
yourself”, refer to Programming spare keys.
Large metallic objects,
electronic devices on
the key chain that can
be used to purchase
gasoline or similar
items, or a second key
on the same key ring
as the coded key may
cause vehicle starting
issues. If present, you
need to keep these
objects from touching
the coded key while starting the engine. These
objects and devices cannot damage the coded key,
but can cause a momentary NO—START condition if
they are too close to the key during engine start. If a
problem occurs, turn ignition OFF and restart the
engine with all other objects on the key ring held
away from the ignition key. Check to make sure the
coded key is an approved Ford coded key.
