Immobilizer Operation

(Key Access)

This vehicle has a passive
theft-deterrent system.
The system does not have to be
manually armed or disarmed.
The vehicle is automatically
immobilized when the key is
removed from the ignition.
The system is automatically
disarmed when the vehicle is
started with the correct key.
The key uses a transponder that
matches an immobilizer control unit
in the vehicle and automatically
disarms the system. The vehicle
may not start if the key is damaged.
The security light, located in the
instrument panel cluster, comes on
if there is a problem with arming or
disarming the theft-deterrent
system.
When trying to start the vehicle,
the security light comes on briefly
when the ignition is turned on.
If the engine does not start and the
security light stays on, there is a
problem with the system. Turn the
ignition off and try again.
If the engine still does not start and
the key appears to be undamaged
or the light continues to stay on,
try another key.
Black plate (24,1)
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 damaged.
See your dealer who can service
the theft-deterrent system and have
a new key made.
It is possible for the theft-deterrent
system decoder to learn the
transponder value of a new or
replacement key. Up to 10 keys
can be programmed for the vehicle.
The following procedure is for
programming additional keys only.
To program a new key:
1. Verify that the new key
1
has stamped on it.
2. Insert the current key in the
ignition and start the engine.
If the engine will not start,
see your dealer for service.
