Hi everyone, I know the "my radio is locked - help!!" issue has been dealt with ad naseum, but after doing my research on forums to try to not re-ask a question, I think this is a new spin on the problem:

I own a 2003 RSX (base, MT) that I purchased from a private party a year ago. They did not provide the radio code when vehicle was purchased. My battery died recently and the radio unit locked up. I extracted the serial number by turning on the unit while holding presets 1 and 6, called the local dealer and they gave me the five-digit radio code. I entered it, and received the same error message I was getting by guessing randomly at the code.

I have repeated the charade with the dealer a few more times to be sure, unfortunately getting the same five-digit code and same result each time. I have also checked the glove box, the cup holders, the ash tray, etc for the code: none have any. The fuse box cover in the engine bay had a five-digit number, but it too resulted in an error message. Finally, just two days ago I had the dealer pull the unit out to see if a different serial number could be gleaned, but no luck. Is there a special way the code must be entered - multiple times or does a certain amount of time have to pass after entering where the radio just sits powered on? I'm out of ideas at this point.

If anyone has a suggestion, I would greatly appreciate it. Thank you for reading!
