Programming Transmitters to the Vehicle

Only keyless access transmitters programmed to this vehicle will work. If a transmitter is lost or stolen, a replacement can be purchased and programmed through your dealer/retailer. The vehicle can be reprogrammed so that lost or stolen transmitters no longer work. Each vehicle can have up to four transmitters programmed to it.

Programming with a Recognized Transmitter

A new transmitter can be programmed to the vehicle when there is one recognized transmitter. For vehicles sold in Canada, two recognized transmitters are required to program a new transmitter.

1. The vehicle must be off.
2. Both the recognized and new transmitters must be with you.
3. Insert the vehicle key into the key 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 FOR FOB 2, 3 or 4.
6. Place the new transmitter into the transmitter pocket, located inside the center console storage area located between the driver and front passenger seats, with the transmiter buttons facing the front of the vehicle.
7. A beep sounds once programming in complete. The DIC displays READY FOR 3 or 4, or MAX # FOBS LEARNED.
8. Remove the transmitter from the transmitter pocket and press twice on each newly programmed transmitter to complete the process.
9. To program additional transmitters, repeat Step 6. Press Acc. on the ignition switch if programming is complete.

Programming without a Recognized Transmitter

This procedure requires three ten minutes cycles to complete the programming process. United States owners are permitted to program a new transmitter to their vehicle when a recognized transmitter is not available. The Canadian immobilizer standard requires that Canadian owners see their dealer/retailer for programming new transmitters when two recognized transmitters are not available.

1. The vehicle must be off.
2. Place the new transmitter into the transmitter pocket, located inside the center console storage area located between the driver and front passenger seats, with the transmitter buttons facing the front of the vehicle.

11. A beep sounds and the DIC reads READY FOR FOB 1. All previously known transmitter programming has been erased.
12. A beep sounds once programming in complete. The DIC displays READY FOR FOB #2.
13. To program additional transmitters, take transmitter 1 out of the transmitter pocket and place transmitter 2 in the pocket. Up to four transmitters can be programmed. The DIC will then display MAX # FOBS LEARNED and will exit the programming mode.
14. Remove the transmitter from the transmitter pocket and press twice on each newly programmed transmitter to complete the process.
