someone does know, it sounds like you need to go buy yourself another ignition lock and two more keys from the dealership or try to figure out the resistance in the pellet on your key. then go to radio shack and buy yourself a resistor of that same value and then cut the connector of the two wires under your dash (purple/yellow and black/white) then solder the resistor in place. either way
you will still have to change out your ignition lock. I don't know what manual you are looking in (haynes or chilton)but I would get rid of them and buy a set of '89 camaro service manuals from the chevrolet dealer service manager. He will have to order them and they will cost about eighty dollars depending on the dealership. You can order them from helms yourself but that will run you about two hundred dollars. If you want the information on the V.A.T. system and how to replace the ignition lock, I have this information in my set of service manuals.
Also, a new V.A.T.ignition lock and two keys will run you around one hundred dollars.
Hope this helps.
