Reprogramming the Remote Control Door Lock Receiver

Important:  The vehicle comes equipped with two transmitters. The receiver can be programmed to accept up to four transmitters. Additional transmitters are available. If the number of transmitters programmed exceeds four, the previously programmed transmitters will be erased in order, starting with the first transmitter.

To program a transmitter, there are 3 modes within the remote control door lock receiver.

    • Add mode: This mode is used for adding new or additional transmitters.
    • Rewrite mode: This mode is used to erase all of the previously programmed transmitters and should be used when installing a new receiver.
    • Confirmation mode: This mode is for confirming how many existing transmitters are registered before adding any transmitters.

To begin programming, follow the procedure.

  1. Set the following conditions:
  2. • Ignition off and ignition key out of cylinder.
    • All doors closed except drivers door.
    • All doors unlocked.
  3. Insert the ignition key into the key cylinder momentarily and remove it.
  4. Using the switch in the drivers door, move the switch to LOCK-UNLOCK 5 times at approximately 1 second intervals within 40 seconds.
  5. Close the drivers door, then open it.
  6. Again, move the switch to LOCK-UNLOCK 5 times at approximately 1 second intervals within 40 seconds.
  7. Insert the ignition key into the key cylinder.
  8. Turn the ignition switch from ON-LOCK at approximately 1 second intervals for 1-3 times according to the desired mode.
  9. • 1 time for add mode
    • 2 times for rewrite mode
    • 3 times for confirmation mode
  10. Remove the ignition key from the key cylinder.
  11. •  If the add or rewite mode has been selected, the doors will lock-unlock once or twice at 1 second intervals, once for add mode or twice for rewrite mode.
    • If the confirmation mode is selected, the doors will lock-unlock 0-4  times at 2 second intervals to inform the technician of the number of transmitters programmed.
  12. Press a transmitter button for 2 seconds. The doors will lock-unlock once at a 1 second interval to inform the technician that the signal has been received from the transmitter.
  13. Close the drivers door, then open it.
  14. Press a transmitter button for 2 seconds. The doors will lock-unlock once at a 1 second interval to inform the technician that the signal has been received from the transmitter.
  15. • If the doors lock-unlock once, the transmitter programming has been completed. Go to step 9 to continue programming for additional transmitters.
    • If the doors lock-unlock twice, the transmitter programming is not complete. Go to step 9 to begin the transmitter programming again.

If any of the following conditions occur during programming, the remote control door lock receiver will return to normal operation:

    • The drivers door remains closed.
    • 20 seconds elapses with no input to the RKE module.
    • The ignition key is inserted into the key cylinder.
    • 4 transmitters have been programmed at once.
