Important: All transmitters that are to be recognized by the remote control door lock receiver (RCDLR) must be programmed in a single programming sequence. If the system is placed in program mode it will erase all previously programmed transmitters upon the receipt of the programming signal from the first transmitter. Up to five transmitters can be programmed. 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.

  2. Install the scan tool.
  3. Select PROGRAMMING KEY FOBS from the BODY menu.
  4. Follow the scan tool instructions with each key until all keys are programmed.
