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 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 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.
At this time, you may also want to
check the fuse. See
Fuses and
Circuit Breakers
on page 10‑48.
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.
It is possible for the PASS-Key
®III+
decoder to learn the transponder
value of a new or replacement key.
