🔹 Step-by-Step Guide

✅ Nissan Key Fob Programming (2000–2006):

  1. Enter vehicle and close all doors. Lock doors using power lock switch on driver’s door.

  2. Insert key into the ignition and remove it — repeat this 6 times within 10 seconds.

    • Do not turn the key, just insert/remove quickly.

  3. Hazard lights will flash twice, confirming entry into programming mode.

    • If not, try up to 10 insertions quickly.

  4. Insert key and turn to ACC (accessory position).

  5. Press any button on the first remote (within 5 seconds).

    • Hazards will flash once to confirm programming.

  6. Repeat step 5 for up to 3 additional remotes (maximum 4).

  7. Turn the key to OFF and remove to exit programming mode.

  8. Unlock doors and test all remotes.

🔹 Notes

  • You must program all fobs during the same session.

  • If you wait too long between steps, the vehicle exits programming mode.

  • This procedure does not program transponder keys, only remotes.

🔹 Troubleshooting

  • Hazard lights didn’t flash? Repeat the 6–10 key insertions faster.

  • Remote unresponsive? Battery could be dead, or the model may not support DIY.

  • Still not working? Some luxury trims or Canadian models may require a scan tool.
