I need to Program my 97 Civic Keyless Entry! help!

Does anybody know how to program a factory keyless entry system for a 97 Honda Civic EX 2Dr. I do NOT have the factory radio, but I think it is still wired in my car somewhere, because my factory keyless entry system worked up until yesterday, when I melted it on my wood stove.

Help! Thanks

Are you talking about the key-FOB? The thing that you push the button on to lock/unlock your doors?
