Where is the radio code on a 2004 Honda Civic?

The radio code on a 2004 Honda Civic is typically located on a sticker inside the glove box or on the underside of the dashboard. This code is required to reactivate the radio if the battery has been disconnected or the radio has been removed from the vehicle.

Finding the Radio Code on a 2004 Honda Civic

The radio code on a 2004 Honda Civic is a security feature that helps prevent theft. When the battery is disconnected or the radio is removed, the radio will become locked and require a code to reactivate it. Here are the typical steps to locate the radio code on a 2004 Honda Civic:

• Open the glove box and look for a sticker or label that contains the radio code. This is often the easiest place to find the code.


• If there is no sticker in the glove box, check the underside of the dashboard. The radio code may be written on a label or sticker in this location.


• If you cannot find the radio code in either of these locations, you may need to contact a Honda dealer or the previous owner to obtain the code.

It's important to keep the radio code in a safe place, as you will need it if the battery is disconnected or the radio is removed from the vehicle.

Entering the Radio Code

Once you have located the radio code, you can enter it into the radio to reactivate it. The process for entering the code may vary slightly depending on the radio model, but generally involves the following steps:

• Turn on the radio and wait for the "CODE" or "ENTER CODE" message to appear on the display.


• Use the radio's buttons or knobs to enter the code digit by digit.


• Once the full code has been entered, the radio should unlock and begin functioning normally.

If you have any trouble entering the code or the radio remains locked, you may need to consult your owner's manual or contact a Honda dealer for further assistance.
