Hello, I just bought a 2006 Ex Coupe Civic. I dont have the code for the radio, however I do have the serial number, can anyone help me with the code. I have checked everywhere for the code (glove box, fuse box, engine, under armrest) and nothing. the serial number is 40048022

 

Go to the dealership and they can look it up for you.

 

What macbeth said, when i bought my car from a dealer (not honda one) the radio was locked and he got it off a Honda dealer. Its pretty easy u just show them your paperwork and they can supply u with it
