Keyless remote

newbe to the forum, (not to computers) so first I would like to say hello to everyone.

I have a 1995 transport with power door locks and auto side door, what I need to find is a remote that will work. I looked at ebay for one, but I am not sure which one will work, or what year model to look at. Does it have to be a 1995 remote?
I have two remotes for a toyota, and would like to know if they can be re-programed for the transport. Or can any one tell me how to find the code so I can do this myself.
