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

One of the most annoying things to deal with when you own a Mercedes is an ignition key that won't work. It could be a sign of other issues, too.

There are three primary causes for Mercedes Benz ignition key problems. The most common causes are a bent key or cable that is loose, as well as an electronic switch that is not working properly.

Loose Cable

Loose cables could cause your Mercedes ignition key to become stuck. This issue can be fixed by tightening the cable near the shifter.

The bolt on the shifter end of the cable has to be tightened up to ensure there isn't any slack in the cable. This is especially important in the event that you drive your Mercedes with the gears set to park since this causes the shifter to move the cable one-sixteenth inch or so, which could cause your key to get stuck.

This loose cable can also cause your key to be bind to the steering wheel lock. This is an essential security feature of your Mercedes since it can stop potential thieves from dragging the vehicle away or using the steering wheel to navigate the vehicle without having a key.

Electronic Switch

The ignition key for the Mercedes is unique to each vehicle, and when you insert it into the ignition system the electronic switch examines the key to make sure it's legitimate. If it's valid, it sends an alert to the steering lock (if your car has one) and other computer modules to unlock the door. This is a great method to get you started in your car quickly and easily -even if you lose your keys, you'll still be able to get in and out of the car without difficulty.

But, despite the fact that we love the convenience of our ignition switches, they can be a source of serious trouble for the road. If the ignition switch you use is not working properly it may not be able to send enough power to your car’s critical electrical components or may be missing vital connections that can prevent the car from starting.

A malfunctioning ignition switch could cause your vehicle to not start at all. This is often due to the fact that the switch doesn’t move to the "on" position, which activates fuel or ignition systems.

Another indication of a damaged ignition switch is that it isn't in the first position, which is where you can examine the dashboard for warning lights. These lights typically turn on when you press the ignition button. They then dim once the car starts.
