Common Causes of Faulty Ignition Switches Ignition switches provide the initial power to your car's accessories as well as the engine. They also determine if the vehicle's keys are in the accessory, on or off position. Keep spare keys, keepsakes, and other items on a chain separate from the key of your car to avoid ignition switch issues. This will help reduce the stress on the key cylinder in your car. How the Ignition Switch Works The ignition switch is at the core of your car. It's the first thing you'll touch when you are getting ready to start your car and the last thing you would want to malfunction. This is why it is essential to have your ignition switch repaired or replaced as soon as you spot any indications of trouble, for example problems getting started or a pulsing motor. The main function of the ignition switch is to provide the initial power to other systems in your vehicle, including radio, accessories, and windows. The ignition switch also activates the engine and starter motor when the key is in the “on” position. The ignition system must work because it needs sparks to ignite the air and fuel in your car to begin. The spark is generated by the ignition coil which creates an electrical field around the rotor whenever current passes through it. When the rotor spins the magnetic field grows, and then the ignition spark is released. The spark will then turn the pistons inside your engine, firing them up and getting it to start. The ignition switch regulates the electrical current flowing through your primary and secondary circuits. When the switch is set to the “on” position, the battery is able to send low voltage current through the primary windings of your ignition coil and then through the points of the breaker. This creates magnetic fields that spin the rotor and ignite your car's spark plugs which then heat up the engine. When the ignition switch is turned to “start” the primary and secondary circuits will be shut off. The electrical connection between distributor cap and rotor terminals break as they rotate. This will stop the secondary flow and completes the circuit. The breaker points are able to close and create a spark at the spark plug which will then ignite the engine within a matter of seconds. Make sure to keep in mind that the ignition switch can be a delicate device that shouldn't undergo excessive force when inserted or turned. If you exert too much force, the switch could fail, and you'll need a professional to remove it to make repairs.

In most instances, a technician must remove the steering column cover and disconnect the switch from the cylinder. They'll then remove the old switch and replace it in. After that the mechanic will re-connect the electrical connections and then test the switch to ensure that it's functioning properly. Certain vehicles have an anti-theft system that requires a particular key to start them and the switch will need to be programmed to accept a new key when the switch is replaced. This does not apply to all cars, as older models can still be started using an ordinary key in the event that the ignition switch fails. Most modern cars require a “chipped” key to start them.
