Well, it could be that you have a loose positive battery terminal, I've had cars that when you turned the key, the accessories worked, but when you turn to start it "clicks", but at the terminal. If your terminal(s) is/are good and tight (cant move it on the post when you try to twist it) it may be the ignition switch and I think it's mounted on top of the steering column and actuated by a rod. You may have to drop the column to change it.
