We're not completely certain where the first key-operated ignition switches appeared. However, we are certain they've made the world safer for our automobiles. Think of the ignition switch as your Mustang's sentry. It acknowledges only the key you were given with the car, bringing your Mustang's engine and all of its accessories to life with a twist. The ignition switch, its lock cylinder, and your key keep things personal.
Things become impersonal whenever the ignition switch or lock cylinder fail to do their jobs. Few things make us feel more defeated than a car that won't start. The truth is, ignition switches rarely fail. They typically work faithfully year after year. However, many classic Mustangs still have their factory ignition switches and lock cylinders, installed when Lyndon Johnson was president. It may be time for a change.
