How to Fix a Mercedes Ignition Key That Won't Work

There are three main reasons for Mercedes Benz ignition key problems. These include a bent key or a cable that is loose, and an electronic switch that is malfunctioning.

Loose Cable

Untight cables could cause your Mercedes ignition key to get stuck. This issue can be corrected by simply tightening the cable near the shifter.

Check that the nut at the end of the cable that connects to the shifter is secured so that the wire isn't sagging.

The loose cable may cause the steering wheel lock to become stuck. This is an important security feature of your Mercedes. It helps prevent thieves from pushing the car away, or using the steering wheel to drive it without a key.

Another issue that could arise with a mercedes ignition switch is that the electronic switch can become worn down and need to be replaced. This is a simple fix that can be done quickly but it is vital to ensure that your new switch is in line with the one you currently have.

Electronic Switch

The ignition switch is an important electronic component of a vehicle. It is equipped with several positions that enable different systems when the key is turned.

Each ignition key for mercedes is unique. When you insert the key into the ignition of your vehicle the electronic switch checks the authenticity of the key.

One of the most frequent symptoms of a faulty ignition switch is that it will not start your car at all. This is often due to the fact that the switch doesn't change to the "on" position, which turns on ignition or fuel systems.

Another indication of a malfunctioning ignition switch is that the key will not go into the initial position, where you can look for warning indicators on the dashboard. These lights typically turn on when you press the ignition key. They dim after your car is started.
