🔹 Step-by-Step Guide

✅ GMC Key Fob Programming Instructions (2000–2006):

  1. Close all doors. Insert key into ignition (don’t turn yet).

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

  3. While holding “Unlock,” turn the key to ON then OFF twice (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 about 15 seconds.

    • Locks will cycle to confirm.

  6. Repeat step 5 for additional remotes (up to 4 total).

  7. To exit, turn key to ON, then OFF. Locks will cycle again.

  8. Test each remote.

🔹 Notes

  • All fobs must be programmed during the same session.

  • Timing is important — repeat steps quickly but smoothly.

  • This does not program transponder ignition keys — only remotes.

🔹 Troubleshooting

  • Doors didn’t cycle? Repeat steps more quickly.

  • Only one remote works? You exited programming before finishing all remotes.

  • No luck? Some Canadian or fleet vehicles may require scan tool programming.
