How do you change the ignition switch?

To change the ignition switch, first disconnect the car battery to ensure safety. Remove any necessary panels or covers to access the ignition switch, then disconnect the wiring harness attached to it. Unscrew the ignition switch from its housing and replace it with the new switch, reattaching the wiring harness. Finally, reassemble any removed components, reconnect the battery, and test the new ignition switch to ensure it works correctly.
