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 4 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.
    • Prohibition mode: This mode is used to erase all registered codes and cancel the wireless door lock function. Use this mode when the transmitter is lost.
    • 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.
    • Drivers door is unlocked.
  3. Insert and remove the key from the ignition switch twice within 5 seconds.
  4. After the above operations, close and open the driver door twice within 40 seconds. Then insert the key into the ignition key cylinder and remove it.
  5. After the above operations, close and open the driver door twice within 40 seconds. Then insert the key into the ignition key cylinder and close the door.
  6. Turn the ignition switch from LOCK to ON and back to LOCK at approximately 1 second interval 1to5 times to select desired mode.
  7. • 1 time for add mode
    • 2 times for rewrite mode
    • 3 times for confirmation mode
    • 5 times for prohibition mode
  8. Remove the ignition key from the key cylinder.
  9. After selecting a mode, the integration relay automatically performs the power door LOCK to UNLOCK operation within 3 seconds to inform the selected mode.
  10. • In the confirmation mode, when the operation is performed twice, it directs that 2 types of recognition codes have been registered.
    • In the confirmation mode, if the number of the registration code is 0 the LOCK to UNLOCK operation is automatically performed 5 times.
    • If the prohibition mode or confirmation mode is selected, registration procedure is completed.
    •  If the add or rewrite 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 to 2 times at 2 second intervals to inform the technician of the number of transmitters programmed.
    • If the prohibition mode is selected, the doors will lock-unlock 0 to 5 times at 1 second intervals.
  11. Registering new recognition codes for the add mode or rewrite mode.
  12. • Within 40 seconds after the add mode or the rewrite mode has been selected, press the LOCK and UNLOCK buttons on the transmitter simultaneously for 1.0 to 1.5 seconds. Within 3 seconds after the previous operation, press either one of the buttons for more than 1.0 seconds.
    • Within 3 seconds after the transmitter has been turned off, the LOCK and UNLOCK operation will be automatically performed once if the registration of the recognition code of the transmitter is completed correctly. In case the LOCK and UNLOCK operation is performed twice, the registration of recognition code has failed. Perform the registration procedure from the beginning once again.
  13. 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.
  14. • If the doors lock-unlock once, the transmitter programming has been completed. Go to step 8 to continue programming for additional transmitters.
    • If the doors lock-unlock twice, the transmitter programming is not complete. Go to step 8 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:

    • Any of the doors are opened.
    • 40 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.
