Radio codes for a 2003 Honda civic coupe si?

Answer 1

The codes for this radio are based on THIS exact radio. If you have lost the code, then you have very few choices. First look long and hard for the 5 digit code. Look in the owner's manual and everywhere it may have been written down. Second, contact the selling dealer where this car was bought new, and see if they have stored the code in their system. And lastly, you will have to get the serial # off the radio. With this serial # the dealer can provide the proper code. To get the serial # you will have to remove the radio from the dash. Sorry, but these are you only choices, as there is no one code for all radios. As I said the code is specific to this radio. Once you get this code, write it down in multible places.

EDIT : Most of the above info is correct up until the part of having to remove the radio to get the serial number. On most Hondas 95-up i think it is, all you have to do is turn the vehicle power on , radio off , press and hold 1 and 6 presets and turn the radio on ( you can let go of the presets after you turn the radio on). It will spit out 4 numbers, wait a sec and another 4 numbers. that's you serial number you will need to show the dealer or you can get the code yourself by entering your info here: https://radio-navicode.Honda.com/

Most codes are on the left outer edge of the glove box when you open it or the inner edge if the dealer did the right thing when the vehicle was delivered to them and PDI correctly.
