The 2003 Honda Civic radio came with a standard theft-deterrent feature for EX and LX models. This feature disables the radio if it should lose its power connection, such as from a dead battery. A code is required to unlock the radio, which was supplied on a card with the original owner's manual at the time of purchase. If you no longer have the card, call a Honda dealer to obtain the original code.

Skill level:


  1. 1

    Turn on the Civic to power the audio system. The radio should read "Code" in its display to signify that a code is necessary to deactivate the theft-deterrent system.

  2. 2

    Enter your five-digit password into the radio by using any of the numbered preset buttons. The preset buttons are labelled one through six.

  3. 3

    Listen for the radio to start playing. If it does not, "Code" should read in the display again. Try to enter the correct code again.

Tips and warnings

  • Go to the Honda Owner Link website to get your passcode online or access your owner's manual for more information. Sign-up is required.
