As you can see, it controls almost all running aspects of your vehicle, so it’s critical for it to work properly. Electrical accessories activate in the first position, power on the fuel and ignition systems on the second position, and the engine cranks on the third. The ignition switch has several positions that power on different systems as the key is turned. We realize that many vehicles are switching to keyless ignitions, but there are still plenty of vehicles that crank by using a physical key. The two work together to turn on and start the vehicle. It’s usually located on the steering column, just behind the ignition lock cylinder, which is where you put your key to crank your vehicle.
