66 dart sedan, slant, original ignition switch. Recently I am noticing that when I stick the key in, and turn it to on, nothing happens. If I jiggle it to the right then the system turns on (lights) and I start it. I can always start it. So it is that On moment, that the lights are supposed to go on that isnt happening consistently. So the key is worn, so I imagine the ignition switch is worn as well. Currently it is keyed to be the same as the driver door. What are my options?
