Keyless Entry Remote Programming Instructions – 1997 Oldsmobile Eighty Eight

Important Notice: This vehicle allows onboard programming using the diagnostic port. All remotes must be programmed during the same session. Any remotes not included will be erased from the system.

Programming Procedure:

• Step 1: Insert the ignition key into the ignition and leave it in the OFF position.
• Step 2: Locate the Data Link Connector (DLC) under the driver’s side dashboard. It is trapezoidal in shape. While the pins are not labeled, refer to the standard layout: Terminal 8: Top row, far right Terminal 4: Bottom row, second from the left
• Step 3: Confirm that both terminals 8 and 4 have metal contacts. Use a jumper wire to connect terminal 8 to terminal 4. Keep the jumper wire in place throughout the procedure. The door locks will automatically lock and unlock, indicating the system has entered programming mode.
• Step 4: Ensure all vehicle doors are fully closed.
• Step 5: Turn the ignition to the ON position (without starting the engine). The doors will lock once more, confirming readiness.
• Step 6: On the first remote, press and hold both the LOCK and UNLOCK buttons simultaneously. After approximately 15 seconds, the doors will lock and unlock again, confirming the remote has been successfully programmed. Release the buttons.
• Step 7: Within 60 seconds, repeat Step 6 for any additional remotes you wish to program.
• Step 8: When finished, remove the jumper wire from the DLC to exit programming mode.
• Step 9: Test all remotes to ensure proper operation.
