Why do I need a 2004 Honda Accord radio code?

Find the Honda Accord audio system code inside your car

Where: There are two places where your Honda radio code might be located: the glove box and the owner’s manual.
What: It’s often written on an “Anti-Theft Radio Code'' sticker in one of these places, either on the glove box wall or the cover of your owner's manual. Your radio code will be a five-digit code—anything else that’s longer or has letters isn’t what you want.  

How to look up your 2004 Honda Accord radio code

If you scraped off the radio code sticker or cannot find your manual, not to worry—you can still get your radio code by contacting a Honda dealership or Honda service center. 
To find your radio code without your sticker or manual, you must:
Find the VIN number: Your
vehicle identification number
(VIN) is usually on your registration, insurance card, or on the bottom of your windshield on the driver’s side. 
Find your radio unit’s serial number: Turn your key to the ON position and press the radio preset buttons 1 and 6 simultaneously. Hold for about ten seconds, and then check the radio display for a 10-digit serial number—write this down.
Contact Honda: Use Honda’s

or call 1-800-999-1009. You can also always visit a Honda dealer or service center for assistance from certified technicians.
FYI, this process is similar across all Honda models. Whether you drive a Honda CR-V, a Honda Civic, or a new Honda Odyssey, you’re looking for a five-digit radio code in your owner’s manual. If you get stuck, contact a local Honda dealer and make a service appointment for your car’s audio system.
