Adding Keys (With SPS)

NOTE:
  • This procedure may be used with or without existing learned keys being present.
  • A total of eight keys maybe be learned to a single vehicle.
  • This procedure will only learn the vehicle key information. This procedure will not learn any immobilizer information between the body control module (BCM) and engine control module (ECM).
  • If the battery voltage is low, charge the battery before continuing with the procedure.
  1. Connect a scan tool to the vehicle and access SPS.
  2. Ensure that all power consuming devices are turned OFF on the vehicle.
  3. Select the SPS application and follow the on-screen instructions.
  4. Select Reprogram ECU.
  5. Select IMMO Immobilizer Learn - Setup.
  6. Select the Program Transponder or Remote Key (Add) function.
  7. Follow the on-screen instructions.
  8. After programming all keys, "Programming Complete" is displayed.
  9. With a scan tool, clear any DTCs.
  10. 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.
