How do you reset my radio after my battery went dead in a 2000 Honda accord?

Unfortunately without a radio code you will have to pull the stereo out and read the serial number off the back and then call your Honda dealer so they can look up the code. you may need to actually go in and prove ownership of the vehicle first. Good luck, Before pulling the stereo- just take a close look in the owners manual ( if you have it) sometimes you get lucky and the previous owner will have written it down somewhere for you.
