Immobilizer Operation
This vehicle has PASS-Key
®
III+
(Personalized Automotive Security
System) theft-deterrent system.
PASS-Key
®
III+ is a passive
theft-deterrent system.
The system is automatically armed
when the key is removed from the
ignition.
The system is automatically
disarmed when the key is turned
to ON/RUN, ACC/ACCESSORY
or START from the LOCK/OFF
position.
You do not have to manually arm or
disarm the system.
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 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.
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 or Roadside
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 the
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.
