Adding Transmitters (Without SPS)

NOTE:
  • To initiate, this procedure requires that 2 learned transmitters be available.
  • A total of eight transmitters can be learned to a single vehicle.
  • This procedure adds transmitters only. The procedure does not erase previously learned transmitters.
  1. Place the recognized transmitters in the vehicle cupholder.
  2. Insert the vehicle key into the key cylinder above the license plate and turn the key to the unlock position five times within ten seconds. The driver information center will display Ready For Remote #2, 3, 4 or 5.
  3. NOTE:

    The transmitter pocket is located inside the center console towards the rear. If a large keyring prevents the transmitter from being placed flat in the pocket, remove the keyring and place the transmitter in the pocket. Failure to fully place the transmitter in the pocket will result in an inability to program.

  4. Place the new transmitter into the transmitter pocket.
  5. Press and release the ignition mode switch. When the transmitter is learned, the driver information center will indicate that it is ready to program the next transmitter.
  6. Remove the transmitter from the transmitter pocket and press the transmitter unlock button. To program additional transmitters, repeat Steps 3 through 5.
  7. When all additional transmitters are programmed, press and hold the ignition mode switch for 15 seconds to exit programming mode.
