Programming Notes:

Obtain all remote transmitters for this vehicle. This procedure will erase all previously programmed remotes. You must program all existing and new remotes that you wish to use on the vehicle at this time. If only one remote will be used you must program it twice for procedure to work.

Step-by-Step Programming Instructions:

  1. Insert key into ignition and turn ignition switch to ON (as far as you can turn without cranking engine).
  2. Locate the RKE module and on the wiring harness will be the programming connector. It should be a single wire that has a green plastic connector and is not connected to anything. Using a jumper wire connect the programming connector to a good ground (unpainted metal surface on body of vehicle). When done properly vehicle will automatically cycle locks to Lock then Unlock.
  3. Now vehicle is in programming mode. Press the UNLOCK button on the first remote two times in one second intervals. Door locks will automatically cycle again to lock then unlock to show that vehicle has accepted remote.
  4. Now whether programming a second remote or just one, repeat Step 3 for either.
  5. Disconnect ground wire. Test all remotes. Programming is complete.
  6. If these programming instructions helped save you time and money, please consider sharing our website with friends and family so they can do the same.
