How do I know If I have keyless entry on my 94z?

Bought the car used, had no key fob but has power windows and locks

 

down in the kickpanel by the passenger, take that off (i think it runs all the way down the door)
there will be a big black box right behind that kickpanel if you have keyless
if there's no box, there's no keyless

if you do have it, get a keyfob off ebay and check shoebox's site on how to program it

 

Look on the RPO sticker in the glovebox for code AU0.
