Hmm...well it could be different I guess...if you can't find it, and want to reset it, then sure, you can do the battery, but you loose your radio presets, etc. On my 99LX I don't have to have a code (or at least didn't need one when I had the stock HU)...I thought you have an LX as well?

And you can get the code yourself...check out honduh sixth gen forum, I have a sticky on it.
