PASS-Key
III Operation

PASS-Key III
uses a transponder in the ignition key
that matches a decoder in the vehicle.
®
When the PASS-Key
III system senses that the wrong
key has been inserted into the ignition, it shuts down
the vehicle's starter and fuel systems. The starter will
not work and fuel will stop flowing to the engine.
If someone tries to start the vehicle again with the
wrong key, the vehicle will not start. Anyone using
a trial-and-error method to start the vehicle will
be discouraged to do so because of the high number
of electrical key codes.
Your vehicle is equipped

with PASS-Key
III
(Personalized Automotive
Security System)
theft-deterrent system.
®
PASS-Key
III is a passive
theft-deterrent system.
This means nothing special
needs to be done to arm
or disarm the system.
It works when the key
is inserted or removed
from the ignition.
When trying to start the vehicle, if the engine does not
start and the STARTING DISABLED warning message
on the Driver Information Center (DIC) comes on,
the key may have a damaged transponder. Turn the
ignition off and try again.
If the engine still does not start, and the key appears
to be undamaged, try another ignition key. At this
time, you may also want to check the fuse. See Fuses
and Circuit Breakers on page 5-93. If the engine still
does not start with the other key, the vehicle needs
service. If the vehicle does start, the first key may
be faulty. See your dealer who can service the
®
PASS-Key
III to have a new key made. In an
emergency, contact Roadside Assistance. See
Roadside Assistance Program on page 7-6 for
more information.
It is possible for the PASS-Key
the transponder value of a new or replacement key.
