Important: Up to 4 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. The order in which the transmitters are programmed is important. The first transmitter programmed will be transmitter #1, and the second transmitter programmed will be transmitter #2. Use care to program the transmitters correctly.

  1. Ignition ON, select Program Key Fobs in the Remote Control Door Lock Receiver Module Setup menu.
  2. Simultaneously press the transmitter LOCK and UNLOCK buttons for 1 second.
  3. Simultaneously press the transmitter UNLOCK and PANIC buttons for 1 second.
  4. If any other transmitters are required to be programmed, repeat steps 2 and 3.
  5. Ignition OFF, verify proper system operation from each transmitter.
