I replace the battery on 2006 honda accord and now my radio isn't working. Is asking me for a code to reset it. How do I get the code.

Dealer would need the serial number to the radio to get the code. This can easily be obtained by holding the #1 and #6 while turning the radio power on. The serial number should pop up (eight digits).

I would first googled it, then if you don't find it, call the service department and ask them about it.

It may be in the same packet as the car manual and other papers.
