PASS-Key ® III+ Electronic
Immobilizer Operation
Your 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 will come on if there is a problem
with arming or disarming the theft-deterrent system.
When the PASS-Key ® III+ system senses that someone
is using the wrong key, it prevents the vehicle from
starting. 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 cluster 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. At this time,
you may also want to check the fuse, see Fuses
and Circuit Breakers on page 6-96. If the engine still
does not start with the other key, your vehicle needs
service. If your vehicle does start, the first key may be
faulty. See your dealer/retailer who can service the
PASS-Key
® III+ to have a new key made. In an
emergency, contact Roadside Assistance.
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 for 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/retailer
or a locksmith who can service PASS-Key
® III+ to
have keys made and programmed to the system.
