Matching Transmitter(s) to Your Vehicle
Each keyless access transmitter is coded to prevent
another transmitter from working with your vehicle.
If a transmitter is lost or stolen, a replacement can be
purchased through your dealer/retailer. Remember
to bring any remaining transmitters with you when you
go to your dealer/retailer. Once your dealer/retailer
has coded the new transmitter, the lost transmitter will
not 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.
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 on the lower
rear fascia on the driver's side of the vehicle.
See Trunk on page 2-13 for more information on
the key cylinder.
4. Open the trunk.
5. Turn the key five times within five seconds.
6. The Driver Information Center (DIC) will display
READY FOR FOB #X. X can be 2, 3 or 4.
7. Place the new, unrecognized transmitter in the
glove box transmitter pocket with the buttons
facing to the right.
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.
