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

There are three main causes for Mercedes Benz ignition keys problems. They are a bent or bent key cable, loose wires, and malfunctioning electronic switches.

Loose Cable

The loose cables can cause your Mercedes ignition key to get stuck. This issue is easily solved with a simple tightening of the cable that connects to the shifter.

Make sure that the nut at the end of the cable that connects to the shifter is secured to ensure that the cable doesn't stretch. This is particularly important in the event that you drive your Mercedes with the gear set to park, since this causes the shifter to move the cable by about a 16th of an inch or so, which could result in your key getting caught.

The loose cable could also cause the steering wheel lock to become stuck. This is an essential safety feature of your mercedes as it blocks criminals from attempting to push the vehicle away or using the steering wheel to steer the vehicle without a key.

This is an excellent way to get started with your car quickly and effortlessly. Even if you lose your keys , you'll still be able to access and leave your car without trouble.
