Your vehicle will be equipped with a standard production random key code if one of the optional fleet codes was not ordered.

For specific key code information, contact your dealer.

Your vehicles will be equipped with a key cylinder in the ignition lock and the driver's door only. Remote keyless entry (RKE) is a standard feature and operates all other doors and the rear liftgate. Six additional RKE transmitters may have been ordered with your vehicle. See your dealer for additional information regarding availability of more RKE units for your vehicle.

Transmitter Programming - SEO AMF

Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle.

Up to four transmitters may be programmed to the passenger door module (PDM). Each programmed transmitter is given a position of #1-#4 in the PDM memory.

All transmitters which are to be recognized by the PDM must be programmed in a single programming sequence. When using this programming method, all previously programmed transmitters will be erased upon the receipt of the programming signal from the first transmitter.

The order in which the transmitters are programmed will determine its numbering position within the PDM memory. The first transmitter programmed will be transmitter #1, and the second transmitter programmed will be transmitter #2. The number stamped on the transmitter case is for reference only. #2 can be programmed as #1, or vice versa. Additional unnumbered transmitters are also available.

The method for programming transmitters is listed in the following steps.

  1. Close all of the vehicle doors.
  2. Insert the ignition key into the ignition lock cylinder.
  3. Press and hold the door unlock switch.
  4. While holding the door lock switch in the UNLOCK position, cycle the ignition on, off, on, off.
  5. Release the door UNLOCK switch. The doors will lock and unlock to confirm the program mode.
  6. Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of about 15 seconds, the doors will lock and unlock to confirm the programming of that transmitter.
  7. Repeat the previous step to program up to four transmitters.
  8. Turn the ignition switch to RUN in order to exit the keyless entry transmitter programming mode.
  9. Operate the transmitter functions in order to verify correct system operation.
