The VIN off the car has nothing to do with the radio code. If you don't have a code card or sticker that has the code on it the only way to get it is to check with the selling dealer to see if it was logged into the PDI if they do not have that info you need to pull the radio and get the serial number OFF THE RADIO to get the security code from Honda.

 

all s2000 radios need the code, atleast here in the states. pretty much all of the newer hondas need them for that matter.

 

Mine's a '99 for Australian market and bought as used ....No coding on it and told AUST models from "99 to '01 were without.....Different radios for us over here....and different band frequencies..
