I bypassed mine too. But it should really be replaced for the safety reason. One day a little kid in the car might turn the key, and you don’t want the car to move or catch fire. On my early 90’s Corolla, this gadget just screws in and out as I recall, installing it is like threading a bolt through a nut. OP – does the new one have a threaded shaft? That’s a clue you just screw it in and out of that hole in the bracket. Measure where the old one is positioned before removing it.
