Loose Cable
Loose cables can cause your mercedes ignition key to be stuck in place. This is an issue that can be resolved with an easy tightening of the cable that connects to the shifter.
The bolt on the shifter end of the cable has to be tightened up to ensure there is no slack left in the wire.

There are many reasons why your Mercedes ignition keys might not be turning. The most frequent reason is an unbalanced or dead battery. This is a common issue for all models and makes of automobiles. You should consult an automotive mechanic to determine the reason.

Electronic Switch
The ignition switch is an important electronic part of a vehicle. As the key is turned, it activates different systems. The first one activates electrical accessories, while the second activates the ignition and fuel systems, and the final cranks the engine.
The ignition key from Mercedes is unique to each vehicle and, when you insert it into the ignition system the electronic switch examines the key to verify that it's valid. If it's valid the key sends an indication to the steering lock (if your vehicle has one) and other computer modules to unlock the door. This is a great method to allow you to start your car quickly and easily -and even if lose your keys, you'll still gain entry and exit without any trouble.
However, while we love the convenience of our ignition switches, they could also create problems for drivers. If your ignition switch is malfunctioning it might not be able to provide enough power to your vehicle's vital electrical components or could be missing connections that may prevent you from starting your vehicle.
One of the most frequent symptoms of a defective ignition switch is that it won't start your car at all. It's usually because the switch doesn't turn to the "on" positionwhich is what powers the fuel and ignition systems.
Another sign of a defective ignition switch is that it won't go into the first position, which is where you can look for warning indicators on the dashboard. Usually, these lights come up when you press the ignition button and then dim once your vehicle is running.
In other situations the dashboard lights remain dark after you turn your key to the "on' position. The reason is that the ignition switch will briefly provide power to the fuel pump and ignition systems if you turn the key to 'on and then it will stop power as soon as the key is removed from the "on" position.
If you have any of these problems, the best option is to seek out a diagnosis from an auto mechanic. An expert will be able to tell you whether the switch is defective or not and what steps to take to fix it.
