✅ Hyundai Onboard Remote Programming Instructions (2000–2004 Models):

  1. Enter the vehicle and close all doors.

  2. Insert key into ignition and turn to “ACC” (accessory), then back to “OFF.” Repeat this 5 times quickly.

  3. On the fifth turn to ACC, press the “LOCK” button on the remote.

  4. The doors should lock and unlock, confirming programming mode.

  5. Press “LOCK” on each additional remote, waiting for the doors to lock/unlock after each one.

  6. Turn the key back to “OFF” to exit programming mode.

  7. Test each remote to confirm functionality.

🔹 Notes

  • Timing is critical — do the ignition steps quickly.

  • Not all Hyundai models in this era support DIY programming.

  • If the above steps don’t work, a professional programmer or dealer tool is likely required.

🔹 Troubleshooting

  • No response from doors? Try again faster.

  • Still not working? Your model likely does not support onboard programming and will need scan tool access.
