Each keyless access transmitter is coded to allow
only transmitters programmed to your vehicle,
to work. If a transmitter is lost or stolen, a
replacement can be purchased and programmed
through your dealer. Your dealer can reprogram
your vehicle so lost or stolen transmitters no longer
work with your vehicle. Each vehicle can have a
maximum of four transmitters matched to it.
To match a new transmitter to your vehicle when
you have a recognized transmitter (two recognized
transmitters are required for Canadian owners), do
the following:
1. The vehicle must be off.
2. Have the recognized and new, unrecognized
transmitters on your person.
3. Go to the rear of the vehicle and insert the
vehicle key into the key cylinder located
above the license plate. See Hatch/Trunk on
page 83 for more information on the key
cylinder.
4. Open the trunk.
5. Turn the key five times within five seconds.
6. The DIC will display READY FOR FOB #X,
where X can be 2, 3 or 4.
7. Place the new, unrecognized transmitter in
the glove box transmitter pocket with the
buttons facing towards the passenger’s side.
8. Once the transmitter is programmed, a beep
will sound. The DIC will display READY
FOR #X, where X can be 3 or 4, or
MAX # FOBS LEARNED.
9. Press the Acc button (ignition switch).
The Canadian immobilizer standard requires
Canadian owners to see their dealer for matching
new transmitters when a recognized transmitter
is not available. United States owners are
permitted to match a new transmitter to their
vehicle when a recognized transmitter is
not available. The procedure will require
three ten minutes cycles to complete the matching
process. Do the following:
1. The vehicle must be off.
2. Place the new, unrecognized transmitter in
the glove box transmitter pocket with the
buttons facing towards the passenger side.
3. Go to the rear of the vehicle and insert the
vehicle key into the key cylinder located above
the license plate. See Hatch/Trunk on page 83
for more information on the key cylinder.
4. Open the trunk.
5. Turn the key five times within five seconds.
6. The DIC message will display
OFF-ACCESSORY TO LEARN.
7. Press the Acc. button (ignition switch).
8. The DIC will read WAIT 10 MINUTES and will
count down to zero, one minute at a time.
9. The DIC will display OFF-ACCESSORY TO
LEARN again.
10. Press the Acc. button (ignition switch).
11. The DIC will read WAIT 10 MINUTES and will
count down to zero, one minute at a time.
12. The DIC will display OFF-ACCESSORY TO
LEARN again.
13. Press the Acc. button (ignition switch).
14. The DIC will read WAIT 10 MINUTES and will
count down to zero, one minute at a time.
15. A beep will sound and the DIC will read
READY FOR FOB #1. At this time, all
previously known transmitters have been
erased.
16. Once the transmitter is recognized and
programmed, a beep will sound and the
DIC will display READY FOR FOB #2.
If you have additional transmitters to program,
take transmitter 1 out of the transmitter pocket and
place transmitter 2 in the pocket. This can be
done repeatedly until up to four transmitters have
be programmed. The DIC will then display
MAX # FOBS LEARNED and will exit the
programming mode.
When you are done programming transmitters,
press the Acc. button (ignition switch).
