This type of ignition can be mounted either away from the cylinder of the lock and controlled by a mechanical linkage or linked to it. Modern ignition switches employ electronic modules to carry a heavy current instead of the traditional tumblers and keys.
There are some common problems with ignition switches, no matter the type you have. Most often, these issues are the result of wear and tear or external influences. A heavy keychain, for instance is a strain on the ignition switch every time it is inserted and removed. This can cause wear to its internals.

Fortunately you can avoid these issues by performing regular maintenance and by identifying early warning symptoms of problems with the ignition switch.
Most ignition switches are designed with four positions: lock, start, acc, and accessory. The lock position blocks the key from being removed, and it's not possible to use accessories or crank the engine while the switch is in this position. The acc position, also known as accessory mode, supplies power to accessories such as the radio while the engine is not running. This mode could drain your battery, so you should be careful when using it.
The starting position is the one that powers everything that makes your engine run. This includes the sensors, coils and gauges in your dashboard. This triggers the engine's spark plugs to start firing and generate combustion, which is what gets your car moving. If you're having difficulty with this position, it may indicate a problem with your ignition switch.
You can test the function of your ignition switch by using a multimeter for checking continuity. You can also see whether the switch functions properly by placing your ignition key and turning the steering wheel left or right.

The power is also cut off to the mechanical lock inside the steering wheel, which means you can't move the wheel when the car is parked. If you try to turn the engine on when the key is in the "parked" position, the anti-theft system will kick in and the car may immediately stop.
Typically the key is kept in this position when you drive. This is due to the fact that it allows you to manage your convenience and auxiliary systems while keeping the engine off and out of reach. Depending on the brand and model of your vehicle the ignition switch could require you to press a little bit before it goes into this position. This is to make sure it can recognize the correct key and doesn't allow a random key to start the engine.

If this is the case, contact a professional.
