What Happens When Your Car Ignition Switch Fails?
The ignition switch in your car is the one that controls a variety of systems, including the engine. It could also be a source of frustration, such as a key that is difficult to turn or dashboard lights that flicker.
The ignition switch operates by using a tumbler to convert your key's movements into positions that trigger different functions. This article will cover the fundamentals of ignition switches, the best way to troubleshoot them, and what to do should they fail.
The Ignition Position
The ignition switch is one of the most crucial car parts but it is often ignored. This small component allows you to turn your engine over and supply power to all of the other systems of your car, including things like the radio, lights, and more. This is why it's so important to keep your ignition switch in good shape and why you need to be aware of what to expect if it malfunctions.
There are many kinds of ignition switches available on market currently, and all perform slightly different functions in accordance with their design. For instance, traditional key operated switches utilize the tumbler, which is specially designed with keys to turn on electrical systems and begin the engine. This type of ignition can be mounted or removed from the lock cylinder and controlled by a mechanical linkage or connected to it. Modern ignition switches utilize electronic modules to transmit heavy current instead of traditional tumblers and keys.
Whatever type of ignition switch you have in your vehicle, however, there are a few common problems that can occur. These issues are typically caused by wear and tear or external influences. A heavy keychain, for instance, can put strain on the ignition switch each time it is inserted and removed. This causes wear to its internals. Extreme temperature fluctuations can affect the lubricants and materials used in the ignition switch. This causes degradation over time.

The acc position, also known as accessory mode, provides the power to devices like radios even when the engine is not running. This mode can drain your battery, so you should be careful when using it.

This activates your engine's spark plugs and ignites combustion and move you. If you have trouble in this position your ignition switch might be malfunctioning.
You can test the operation of your ignition switch by using a multimeter to check continuity. You can also check if the switch is working correctly by placing your key in the ignition and turning the steering wheel left or right. If you notice that the gears are difficult to turn or the ignition switch is leaking then you must consult your local locksmith.
A defective ignition switch can cause your car to be difficult to drive by making it difficult to turn the steering wheel. This is a sign that the ignition switch needs to be fixed.
The Stop Position
When the key is in this position, all circuits that receive electricity from the ignition switch are turned off. This includes all auxiliary systems like your radio, dash light, and even your power seats. It also cuts the electrical power to the mechanical lock inside the steering wheel so you aren't able to turn the wheel if the vehicle is stationary. If you try to turn the engine on while the key is in the "parked" position the anti-theft system will kick in and the car could stall.
This is the most common position for the key when driving. This is because you can manage your auxiliary systems and convenience features while keeping the engine off. Depending on the make and model of your vehicle the ignition switch could require you to press in a bit before it goes into this position. This is to ensure that it recognizes the correct key and doesn't permit a random key to start the engine.
You may experience different symptoms if your ignition switch is worn out. The most frequent symptoms include the engine not starting, difficulty in turning the key, and sudden failure of the accessory or other features. The ignition switch is a specialized component that requires professional replacement by an experienced auto mechanic.

Once you've gained access to the cylinder, loosen the nut on the negative terminal and then remove it from the cable. Check the owner's manual for details on how to safely disconnect the battery and where it's situated.
The accessory position

The ignition switch might be malfunctioning if your car key isn't easy to turn or if it will not turn at all. It's sometimes difficult to tell if the issue is with the switch or the key.

There's typically a brown, red, and pink wire, however, only the red wire is usually hot when the switch is in the accessory position. If the wire is not powered, the ignition switch may be damaged.
