Now that you have everything prepared, follow these simple steps for 2003 hyundai elantra key fob programming:
- Get Inside Your Vehicle: Enter your 2003 Hyundai Elantra and close all doors. Ensure all doors are properly shut.

- Press the “UNLOCK” Button: After releasing both buttons, press and hold the “UNLOCK” button on the key fob for about one second and release.
