How do you remove and replace the ignition switch on semi truck?

Answer 1

Need to know make and model in order to answer this. On some, you simply use a key to remove the panel which the switch is mounted to, unplug the wires from the back of the switch, use a small pick to remove the tumbler from the housing, pop a new housing into the tumbler, and put it back in the opposite of how you took it out.
