🔹 Step-by-Step Guide (Standard GM Procedure):

✅ Programming Chevy Key Fob (2000–2006, most models):

  1. Close all doors, insert key into the ignition (but do not turn yet).

  2. Hold the “Unlock” button on the driver’s door — do not release.

  3. While holding “Unlock,” turn the key to “ON” then back to “OFF” twice quickly (within 10 seconds).

  4. Release the “Unlock” button. The doors will lock and unlock to confirm programming mode.

  5. On the first remote, press both “Lock” and “Unlock” buttons at the same time, hold for 15 seconds until the door locks cycle again.

  6. Repeat step 5 for additional remotes.

  7. To exit, turn the ignition to “ON” (not start), then back to “OFF.”

  8. Test each remote to confirm.

🔹 Notes

  • All fobs must be programmed during the same session.

  • Not all models support onboard programming (some require a scan tool).

  • Timing matters — perform the steps smoothly and without long pauses.

  • 🔹 Troubleshooting

    • If programming mode doesn't activate: double-check door is fully closed, and key turns are fast enough.

    • If locks don’t cycle: restart the entire process from step 1.
