I just recently performed a service on my car in which i had to unwire the battery. Upon turning everything back on, my radio asked for a code which i retrieved. However the code has zero's "0" in it (2 to be exact) how do i enter them???? It is a Honda accord 2004 ex sedan

 

look for a different card? many of us received two code cards with our cars, only one worked. I haven't seen zero's for a code b4.

I have a 2004 honda accord and changed the battery and the radio is asking for a code...I have the serial number...can anyone help me?

 

You can go to any Honda dealer and get the code for your radio with the proof of ownership. Used to just call up to the dealer and they will give it to you, but not any more now. Radio-code.com can get it for you for a fee of $20.
