Programming Guide for 1996 Keyless Entry Remote Fob

Important Notice: The 1996 model supports onboard programming for remote keyless entry fobs. This manual procedure uses the vehicle’s Data Link Connector (DLC) and allows up to two remotes to be programmed. This guide does not apply to ignition key programming.

Programming Procedure:

  • Step 1: Sit in the driver’s seat and ensure all doors are fully closed.
  • Step 2: Insert the key into the ignition and leave it in the OFF position.
  • Step 3: Locate the Data Link Connector (DLC) beneath the dashboard on the driver’s side. The connector is rectangular and wider at the top. Use this shape to properly orient and identify the terminal layout.
  • Step 4: Identify terminals 8 and 4. The port may not be labeled, so use the orientation to determine the correct terminal positions. Ensure both terminals have visible metal contacts.
  • Step 5: Use a jumper wire to connect terminal 8 to terminal 4. Keep the wire connected throughout the entire procedure. When the connection is made, the door locks should cycle (lock and unlock), indicating that the system has entered programming mode.
  • Step 6: Confirm the door is still closed before proceeding.
  • Step 7: Turn the ignition key to the ON position (one click before engine start). The door locks will cycle again to confirm readiness.
  • Step 8: On the first remote, press and hold both the LOCK and UNLOCK buttons simultaneously. Hold both buttons for about 15 seconds, or until the locks cycle again. This confirms that the remote has been successfully programmed.
  • Step 9: If programming a second remote, repeat Step 8 within one minute of programming the first.
  • Step 10: Once all remotes are programmed, turn the ignition back to the OFF position and remove the jumper wire from the DLC.
  • Step 11: Test each remote to confirm full functionality, including lock and unlock commands.

Additional Considerations:

Maximum Remotes: This system supports programming of up to two remotes.

Battery Health: Ensure each remote fob has a working battery before starting the procedure.

Ignition Key Programming: This procedure does not support ignition key programming. A technician with the appropriate tools is required for that process.

Repeat if Unsuccessful: If any step fails or the locks do not respond, restart the process from Step 1.
