Programming with TWO Recognized Transmitters

A new transmitter can be programmed to the vehicle when there are two recognized transmitters. To program, the vehicle must be off and all of the transmitters, both currently recognized and new, must be with you.

1. Place the two recognized transmitters in the cupholder.

2. Remove the key lock cylinder cap on the driver door handle. See Door Locks pg. 35.

3. Insert the vehicle key of the new transmitter into the key lock cylinder on the outside of the driver door and turn the key to the unlock position five times within 10 seconds. The Driver Information Center (DIC) displays READY FOR REMOTE #2, 3, 4 or 5.

4. Place the new transmitter into the transmitter pocket inside the armrest storage area.

5. Press ENGINE START/STOP. When the transmitter is learned, the DIC will show that it is ready to program the next transmitter.

6. Remove the transmitter from the transmitter pocket and press UNLOCK.

To program additional transmitters, repeat Steps 3–5. When all additional transmitters are programmed, press and hold ENGINE START/STOP for 12 seconds to exit
programming mode.

7. Put the key back into the transmitter.
