I have a 1996 Explorer that I use as a winter vehicle and I recently programmed another remote that I had just purchased, since the vehicle only came with 1 keyfob (remote 2) when I bought it. Now after programming the new one, the old one won't work. I have tried to reprogram the old one, but then I lose the new one. Is there a way to program both remotes to work?

You have to program both at once. So before you exit your programming (right after you've press the button on your first one and the locks have cycled) press the button for the second one. The locks will cycle. Then exit. You should now have both programmed.

What's happening is that when you program a new remote in it deletes the old codes out, so basicaly you have to do both at once.
