The Importance of Ignition and Key Replacement The ignition switch is a simple but vital component of your car's starting system. It transforms the power of the battery in your car into a spark which ignites fuel and then starts your engine. Like every other system the ignition switch is no exception.

Your ignition switch has three major settings: accessory, off, and on. In the off position, the key can be removed but nothing else turns on. This turns off all systems that do not require starting your engine, such as the dome lights as well as some of the door locks. The accessory position (also known as ACC) lets you use some of your car's non-ignition-controlled systems, like the radio and power windows. To turn on your car, the ignition switch must connect to the circuit that provides power to the starter motor. To do this, the ignition switch must first be unlocked from the ignition cylinder. This is done electronically, by acknowledging the key cut. A small tumbler is responsible for locking and unlocking your ignition switch. It should be able to match the unique cut of your key. The tumbler has different ramps on each side and, when you insert your key it pushes the key into the different ramps to trigger the system in the most appropriate manner.

The on position powers the starter and the start position occurs when you turn your engine over to start it. The ignition switch's inside contains a set of contacts that close when you alter the position. The contacts don't have a high current passing through them, but rather they are relays that allow the functions to function. They are susceptible to a lot of wear and tear over time. They also can fail due to age, heat, or even heavy key chains. Additionally the ignition switch comes with a mechanical lock inside of it, which protects your vehicle while it's stationary.
