How do i program keyless entry remotes?

I bought my 96 Camaro used. It only came with 2 keys, no remotes. I am wondering if i can get a remote and program it, i have power locks (came with car, not aftermarket) and power trunk. If it is possible to program a remote i need to know how so i can buy one and program it.
Any help is GREATLY appreciated!

What makes you think that it had keyless entry? and if you remove your passenger kick panel. If there is a square black box in there. Then you have it.

just cuz it has power locks dosnt mean it has keyless entry, make sure the car has it before you buy the remotes. the dealership can decode your spid lable and tell you if it has it or not.

Thats what i needed to know. Thank you guys much.
