the security light on the instrument
panel comes on when trying to start
the vehicle, there may be a problem
with your 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. See Fuses
and Circuit Breakers on page 10‑32
for additional information. If the
engine still does not start with the
other key, the vehicle needs service.

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

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 the
currently programmed keys are
lost or do not operate, you must
see your dealer or a locksmith who
can service PASS-Key

keys made and programmed to the
system.
