Replacing Transmitters (Without SPS)

WARNING: This page is about a different car, the 2015 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • Verify all mechanical keys operate correctly before beginning any programming procedures.
  • This procedure will unlearn all previously learned transmitters. All transmitters that are to be programmed must be with the vehicle at the time of service.
  • This procedure will take approximately 35 minutes to complete.
  • A total of 8 transmitters can be learned to a single vehicle.
  • This procedure will only learn the vehicle transmitter information. This procedure will not learn any immobilizer information between the body control module (BCM) and engine control module (ECM).
  • This procedure may be used with or without existing learned transmitters being present. If existing transmitters are present, keep the transmitters away from the vicinity of the vehicle. Failure to keep learned transmitters away from the vehicle will result in the learn changing to the Adding Transmitters procedure.
  1. Insert the mechanical key of the new transmitter into the key lock cylinder located on the outside of the driver door and turn the key to the unlock position five times within ten seconds. The driver information center will display Remote Learn Pending, Please Wait.
  2. After ten minutes, the driver information center will display Press Engine Start Button To Learn. Press the ignition mode switch. The driver information center will again display Remote Learn Pending, Please Wait.
  3. Repeat Step 2 two additional times, for a total of thirty minutes. All previously known transmitters have now been unlearned. Remaining transmitters can be relearned during the next steps. The driver information center display will now display Ready For Remote # 1.
    4. NOTE:

    The transmitter pocket is located inside the center console storage area, near the front of the storage compartment. If a large keyring prevents the transmitter from being placed fully into the pocket, remove the keyring and place the transmitter in the pocket. Failure to lay the transmitter fully into the pocket may 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 unlock button. To program additional transmitters, repeat Steps 4 through 6.
  7. When all additional transmitters are programmed, press and hold the ignition mode switch for 15 seconds to exit programming mode.
  8. Verify each transmitter and key is operating properly. Operate each of the keyless entry functions using the buttons on the transmitter. On vehicles with a keyed ignition switch, verify the mechanical key by starting the vehicle using the ignition switch. When verifying operation, make sure that no other transmitters are near the vehicle.
