2-24 Keys, Doors, and Windows
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 in the instrument
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.
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 has
1
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.
3. After the engine has started, turn
the key to LOCK/OFF, and
remove the key.
4. Insert the key to be programmed
and turn it to ON/RUN within
five seconds of the ignition being
turned to LOCK/OFF in Step 3.
5. The security light will turn off
once the key has been
programmed. It may not be
apparent that the security light
went on due to how quickly the
key is programmed.
