This is why it is so important to maintain the ignition switch and what happens if it malfunctions.
There are many kinds of ignition switches on the market today, and they have different functions depending on their design. Key operated switches, like, use a tumbler and specially shaped keys to start the engine and also activate electrical systems. This type of ignition is mounted or removed from the lock cylinder, and operated by mechanical linkage or connected to it. Modern ignition switches run high currents using electronic modules instead of tumblers and key.
No matter what kind of ignition switch you are using in your vehicle, however, there are a few common issues that can arise. Most of the time these issues are caused by wear and tear or external forces. A heavy keychain, for instance is a strain on the ignition switch every time it is removed and inserted. This causes wear to the internals of the switch. Also, extreme temperature changes can impact the lubricants and materials in the ignition switch, leading to degrading over time.

The Start Position
A car ignition switch is a small piece of machinery that can make an enormous difference in the manner in which your car operates. With a single flick of a switch or push of the button, it will start your engine as well as numerous other systems. It's an essential component of your vehicle, allowing you to go on the road quickly and safely. Like every other piece of machinery it will encounter issues periodically. These problems can not only prevent your vehicle from starting, but also damage other components. Fortunately you can prevent these issues with regular maintenance and by identifying early warning signs of ignition switch problems.
The majority of ignition switches are constructed with four positions: lock, start, acc, and accessory. The lock position blocks the removal of the key and you can't use accessories or crank your engine when the switch is in this position. The acc position, or accessory mode, gives the power to devices like radios even when the engine is not running. However, this option can drain the battery, so it is essential to use the acc position in moderation.
The starting position is where your engine runs. This includes the gauges, sensors, and coils in your dashboard. This also triggers the spark plugs of your engine to ignite and produce combustion, which is what gets your vehicle moving. If you're having difficulty in this position, your ignition switch may be malfunctioning.
Multimeters can be used to test the operation of the ignition switch. You can also check whether the switch is functioning correctly by placing your key in the ignition and turning the steering wheel left or right. If you notice that the wheels are difficult to turn or the ignition switch is leaking it is recommended to contact your local locksmith.
A malfunctioning ignition switch could also make it difficult to drive your car by making it difficult to turn the steering. This could be a sign of an issue in the ignition switch that needs to be fixed, so it's recommended that you take your car into an expert as soon as you notice any issues.
The Stop Position
When the key is in this position all circuits that get electricity from the ignition switch are cut off. This includes auxiliary systems such as your radio, dash lights, and some of your power seat. The power is also cut off to the mechanical lock in the steering wheel, so you aren't able to move the wheel while the vehicle is stationary. If you try turning the engine while the key is in the "parked" position the anti-theft mechanism will be activated and the car will stall.
This is the standard location for the key when driving. This is due to the fact that it allows you to manage your convenience and auxiliary systems while keeping the engine off and away from reach. Depending on the make and model of your vehicle the ignition switch may require you to press in a bit before it goes into this position. This is to ensure it is able to recognize the correct key and doesn't let a random key start the engine.
You might experience a variety of symptoms if your ignition switch is faulty. Some of the most common symptoms are the engine not running, difficulty turning the key and sudden malfunction of accessories or other features. The ignition switch is a complicated component that requires a professional replacement by a skilled auto mechanic.
To replace the ignition switch, you'll have to disconnect the negative terminal of your battery. Remove any plastic pieces or covers that cover the ignition cylinder. Once you have gained access to the cylinder, pull the cable away from the negative terminal. Refer to your owner's manual for instructions on where the battery is and how to disconnect it safely.
The Accessory Position
The ignition switch may be one of the smallest parts in your vehicle, but it's crucial to the vehicle's function. It's a frequent point of failure and it's crucial to understand what happens if your ignition switch fails. You must also be able to determine the problem and fix it.
Most people don't think about the ignition switch until it fails to perform as it should. The switch is responsible for enabling nearly every part of your vehicle to function and prevent many issues from occurring. The key is inserted into a small cylinder, and the switch activates it to allow power flow to other systems.
Modern ignition switches are electronic and not mechanical gears. They do the same thing - they activate nearly all your vehicle's systems. In extreme cases a defective switch can cause your engine to overheat or cause the car to catch fire.
The accessory position, known as ACC in your car's manual permits you to turn on accessories such as your headlights, radio, and other electrical devices. These devices don't draw the massive current needed to start your engine because they draw the power directly from your battery. This is the ideal location to listen to music or other devices while driving, but be careful not to allow it to be on for too long.
The ignition switch might be malfunctioning if the car key isn't able to turn or if it won't turn at all. It's sometimes difficult to tell if the issue is with the switch or the key. Examine the key for signs of scratches and dents. Also, determine if the key is stuck in the ignition. You can also examine the wiring inside the ignition switch. When the key is in accessory mode there's usually a brown, pink and red wire. However, only the red wire is usually hot. If the wire is not powered, the ignition switch may be damaged. If this is the situation, contact an expert.
