Key Fob programming?

[amagalla]

I know that the code is in the fob. The problem that I see is that there are TONS of fobs out there that can't be used because the owner didn't retain the programing tag with the code on it (who does). What I'm asking is; "Is there the possibility that the code is stored on one of the chips on the fob? And if so, is it recoverable if it can be read with an eprom reader?" If the programing code that is normally on the tag is stored in one of the eproms, and it's readable, that means all those paperweights are now useful fobs.
