Method 2 - Erasing/Adding Transmitters (No Known Transmitter Available)

WARNING: This page is about a different car, the 2013 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.

This procedure will first erase all known transmitters. The procedure will then program a single transmitter or multiple transmitters. Method 2 is a series of three 10-minute key cycles, for a total of 30 minutes. This procedure requires that you have a replacement transmitter and the vehicle's mechanical key.

NOTE:

Do not place any known good transmitters within 10 feet of the vehicle when programming with Method 2. If the RCDLR recognizes a known good transmitter during Method 2 programming, the programming mode will resort to Method 1.

  1. The vehicle must be OFF.
  2. Insert the vehicle key in the lock cylinder located in the driver door handle (sedan and wagon) or above the license plate (coupe) and cycle the key 5 times within 5 seconds.
  3. The DIC will display a message: PRESS START CONTROL TO LEARN.
  4. Press in on the start control knob.
  5. The DIC will display a message: WAIT 10 MINUTES, and then begin to count down from 10 to 0, one minute at a time.
    6. NOTE:

    Once the timer has expired, it is necessary to proceed to the next step within 5 minutes. Failure to do so will result in the exiting of the program mode and the procedure will have to be restarted at step 1.

  6. When the counter reaches 0, DIC will display: PRESS START CONTROL TO LEARN.
  7. Repeat steps 4-6 two more times, for a total of 30 minutes.
  8. At the end of the 30 minute cycle, a beep will occur and the DIC will display: READY FOR ELECTRONIC KEY 1. At this time all previously known transmitters have been erased.
  9. Place the new/replacement transmitter in the console bin pocket with the buttons facing forward and keychain provision facing up. When transmitter 1 is programmed, a beep will be heard and the DIC will display: READY FOR ELECTRONIC KEY 2.
  10. Additional transmitters can be programmed by taking transmitter 2 out of the pocket and inserting transmitter 3. If desired, up to 4 transmitters can be programmed. Once 4 transmitters have been learned, the DIC will display a message: MAX ELECTRONIC KEYS LEARNED, and automatically exit the program mode.
  11. If learning less than 4 transmitters, press in on the start control knob to exit the program mode.
    12. NOTE:

    Newly programmed transmitters will not function until program mode has been exited (DIC is blank). This must be done prior to pressing the trunk release button in the next step.

  12. Press and hold the transmitter trunk release or liftgate release button for one second on each transmitter that was programmed to finalize the programming and confirm system operation. Multiple button presses may be required before the trunk or liftgate responds.
