every stereo has a different unlock code. the default 5-digits could be 0-0-0-0-0 or 1-2-3-4-5. Be careful because if you try to many times and fail, the stereo will completely lock and you will have to reset it by unplugging the battery(not recommended). You can also go to the Honda dealer, they will unlock the stereo for a fee!. It can also be written somewhere in the little trunk or in the owners manual. I hope it helps you!!
