Same thing happened to me awhile back. They wanted $80 for the code. The guy said "80 bucks". I said "Come on, man". He said "sorry bud, take it or leave it". I said loudly "$80? NO, I ALREADY HAVE THE RADIO, I JUST NEED THE CODE." The service/parts desk was acutally in the showroom and the guy stared me down like he wanted to punch me. I moved closer and quietly told the guy that I was on my 5th Honda, and I wasn't about to pay $80 for a code on a car I paid $21,000 for, and if he didn't give it to me, I had no problem making a fool of myself. He gave me the code, but no smile.
Sometime those Honda dealers get a little conceited. Just need some coaxing.
