Please Help me program keyless remote

I have an ALPS keyless entry remote p/n 10178734 for a 1994 Cadillac Eldorado Touring Coupe that stopped working recently. I replaced the battery and it still does not work. I think I need to reprogram the remote so it will work again. Please send programing instructions ASAP.
PLEASE HELP!!!

THANK YOU!!

If it's like most other GM remotes, stand near the car and press and momentarly hold both, "lock" and "unlock" at the same time. That should do it. it works for mine.
