Car outlived its Key Fob

We have a 1995 Honda Odyessy that has outlived its key fobs. Apparently it was the first year that honda made them, and the Hoda dealership in Berkeley says they are no longer available and cant even be catalogued because they are obsolete. Well, they arent obsolete to us, in fact, we desperately need one.. Anyone have any ideas how to get replacements?
