Super easy. Turn your radio off, press the numbers 1 and 6 simultaneously, then turn on the radio. It should show you a U And L number. Write the numbers down, and go to this link. https://radio-navicode.honda.com . Then put in the U and L numbers together in the serial number without the letters U and L. And put in your Vin number, phone and email. It will give you a code, so enter that into your radio! I didn't want to call Honda too so here you go.
