97 Camaro keyless programming

I just bought a 97 Camaro Z28 with automatic everything. The only problem is that it did not come with a keyless remote. It has a factory alarm system installed so it must have originally come with the keyless remote...right? Anyway, I found 3 keyless remotes on ebay (I know I've read a couple horror stories) P/N 16245100-29. The seller claims these remotes are good for "1997 TO 01 CAMARO OR FIREBIRD". If I were to purchase a working remote, how would I program it for my car?:confused:
