Keys, Doors, and Windows 2-15
The security light comes on if there
is a problem with arming or
disarming the theft-deterrent
system.
When the PASS-Key III+ system
senses an incorrect key, the vehicle
does not start. Anyone using a
trial-and-error method to start the
vehicle will be discouraged because
of the high number of electrical key
codes.
If the engine does not start and the
security light on the instrument
panel comes on when trying to start
the vehicle, there may be a problem
with the theft-deterrent system.
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 and check
the fuses. SeeFuses and Circuit
Breakers on page 10‑31 for
additional information. 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 (U.S. and
Canada) on page 13‑8 orRoadside
Assistance Program (Mexico) on
page 13‑10.
It is possible for the PASS-Key III+
decoder to learn the transponder
value of a new or replacement key.
Up to 10 keys may be programmed
to the vehicle. The following
procedure is for programming
additional keys only. If all currently
programmed keys are lost or do not
operate, you must see your dealer
or a locksmith who can service
PASS-Key III+ to have keys made
and programmed to the system.
See your dealer or a locksmith who
can service PASS-Key III+ to get a
new key blank that is cut exactly as
the ignition key that operates the
system. To program the new additional key:
1. Verify that the new key has a
1
stamped on it.
2. Insert the already programmed key in the ignition and start the
engine. If the engine does not
start, see your dealer for service.
