For vehicles sold in Canada, two
recognized transmitters are required
to program a new transmitter.

2. Place the recognizedtransmitter(s) in the cupholder.
Have the new transmitter
available with you.
3. Insert the vehicle key into the key lock cylinder located on
the outside of the driver door.
4. Turn the key to the unlock position five times within
five seconds.
5. The Driver Information Center (DIC) displays READY TO
LEARN ELECTRONIC
KEY #2, 3 or 4.
6. Place the new transmitter intothe transmitter pocket with the
buttons facing the front of the
vehicle. The transmitter pocket
is inside the center console
storage area located between
the driver and front passenger
seats.
7. A beep sounds once the transmitter is programmed. The
DIC displays READY TO LEARN

Programming without a
Recognized Transmitter

vehicle when a recognized
transmitter is not available. The
Canadian immobilizer standard
requires that Canadian owners see
their dealer for programming new
transmitters when two recognized
transmitters are not available.

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.
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.
6. Repeat Steps 1 through 4 if additional keys are to be
programmed.
Do not leave the key or device that
disarms or deactivates the theft
deterrent system in the vehicle.
Immobilizer Operation
(Keyless Access)
This vehicle has a passive
theft-deterrent system.

The vehicle is automatically
immobilized when the ignition
control knob is turned to LOCK/OFF.
The immobilization system is
disarmed when the ignition control
knob is pushed in and a valid
transmitter is found in the vehicle.
The security light, located in the
instrument panel cluster, comes on
if there is a problem with arming or
disarming the theft-deterrent
system.

Keys, Doors, and Windows 2-27
One or more keyless access
transmitters can be matched to the
vehicle's immobilizer control unit.
Only a correctly matched keyless
access transmitter will start the
vehicle. If the keyless access
transmitter is ever damaged, you
may not be able to start your
vehicle.
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 control knob off and try
again.If the ignition control knob does not
rotate, and the keyless access
transmitter appears to be
undamaged, try another keyless
access transmitter. Or, you may try
placing the transmitter in the
transmitter pocket located in the
center console. See
“Electronic Key
Not Detected” underKey and Lock
Messages on page 5‑37.
If the ignition control knob still does
not rotate with the other transmitter,
the vehicle needs service. If the
ignition control knob does rotate, the
first transmitter may be faulty. See
your dealer who can service the
theft-deterrent system and have a
new keyless access transmitter
programmed to the vehicle. It is possible for the immobilizer
system to learn new or replacement
keyless access transmitters. Up to
four keyless access transmitters can
be programmed for the vehicle. To
program additional transmitters, see
“Programming Transmitters to the
Vehicle”
for keyless access under
Remote Keyless Entry (RKE)
System Operation (Key Access) on
page 2‑5 orRemote Keyless Entry
(RKE) System Operation (Keyless
Access) on page 2‑6.
Do not leave the key or device that
disarms or deactivates the theft
deterrent system in the vehicle.
