You will need to change the ignition switch as the tumblers went bad inside of it. If you can get the switch apart, you can manually start it with a slotted screwdriver, as the end of the ignition switch inside the column has a rectangle shaped tab on it that rotates and turns the mechanism inside the steering column when the key is turned to start position. You have to remove the steering wheel to get at the set screw that holds the ignition switch inside the steering column to change it. There isn't any electrical to the key switch, that is all connected to the mechanism that the key switch turns, so it's a fairly easy repair once you pull your steering wheel and remove the turn signal mechanism.
