How to Fix a Mercedes Ignition Key That Won't Work
An ignition key that does not work is one of the most frustrating issues you'll face when driving an Mercedes. It can be an indicator of other issues, too.
There are three primary reasons for Mercedes Benz ignition keys problems. These include a bent key or cable that is not in good condition, and an electronic switch that is not working properly.
Loose Cable
Cables that are loose could cause the ignition key of your Mercedes to get stuck. This issue can be corrected by simply tightening the cable near the shifter.
The bolt on the shifter end of the cable has to be tightened to ensure that there isn't any slack in the cable. This is particularly important if your Mercedes is in park position. The shifter will move the cable by about one sixteenth inch and this could cause your key to get stuck.
The loose cable could cause your key to be tied to the lock on your steering wheel. This is an important safety feature of your Mercedes. It stops potential thieves from driving the car away or using the steering wheel to steer without a key.
Another issue that can arise when using a mercedes ignition key is that the electronic switch could get worn out and need to be replaced. This is a simple repair that is quick and easy to do, but it is important to ensure that you match the new switch to the one you currently have.
A malfunctioning switch can lead to a variety of issues, like your car stalling, the lights going out or the radio not working when you turn your key. You can bring your Mercedes to the repair shop or purchase a replacement OEM Mercedes ignition button.
Certain ignition keys of Mercedes can also be locked even when the vehicle is in park. This is a typical issue in older Mercedes models and is usually caused by loose cables that connect the locking mechanism of your ignition assembly to the shifter.
If you have a key that is locked in place, try a jump start to try to resolve the issue. This is a great way to test the battery and it's a quick and inexpensive solution.
There are a variety of other reasons that your mercedes ignition keys might not turn but the most common is an unresponsive battery. This is a common issue for all makes and models of cars. It is recommended to consult an automotive mechanic to identify the exact reason.
Electronic Switch
The ignition switch is a crucial electronic part of a vehicle. When the key is turned, it triggers various systems. The first position activates electrical devices, the second position turns on power on fuel and ignition systems, while the third cranks the engine.
The ignition key for the Mercedes is unique to each car and, when you insert it into the ignition system, the electronic switch checks the key to verify that it's valid. If it's valid the key sends signals to the steering lock (if your car has one) and other computer modules to unlock the door. This is a great method to get started with your car swiftly and easily. Even if you misplace your keys , you'll still be able to be able to get into and out of your car without difficulties.
However, even though we enjoy the convenience of our ignition switches, they can create serious issues for the road. If your ignition switch is malfunctioning it might not be able to provide enough power to your car's crucial electrical components or be missing connections that can prevent the car from starting.
A defective ignition switch can cause your vehicle to not start at all. Often, this is because the switch doesn't move to the 'on' position -- which powers on fuel and ignition systems.
A malfunctioning ignition switch may cause the key to not be able to go into the first position. This is where you should check for warning lights on your dashboard. These lights usually turn on when you press the ignition key. They then dim when the car starts.
In some instances the dashboard lights remain dark even after you turn the key to "on". The reason for this is because the ignition switch will temporarily provide power to the ignition and fuel pump systems if you turn the key to 'on', but then it will cut off power as soon as the key is removed from the "on" position.
You should consult an auto mechanic if you experience any of these issues. A qualified mechanic can tell whether the switch is malfunctioning and the steps to do to fix it.
Steering Wheel Lock
Mercedes ignition keys have been designed with an anti-theft feature in mind. If someone attempts to steal your vehicle and manages to move the steering wheel, even though you're away, it will activate the locking mechanism on the steering wheel and prevent the vehicle from moving.
This safety measure is designed to guard you and your family from being harmed in the event of a crime. It also stops thieves from stealing your car.
But, in some cases, the lock won't open, or it may be locked. It can happen for many reasons, including damaged or worn out ignition tumblers. You can either purchase the key replaced or fix the issue yourself.
To fix this, you'll have to remove the ignition lock assembly. To do this, you must remove the plastic cover that covers the ignition and take out the fasteners.
After you've removed the ignition lock assembly, it is possible to replace it with a brand new one. It is important to ensure that the new component is a perfect match to the car's components. This will ensure that the locking mechanism will work correctly when you install it.
You should also ensure that the new ignition lock is properly installed and that all clips are engaged correctly. This is especially important for older models.
Wear and tear on the tumblers can cause your Mercedes ignition keys to become stuck in their locked position. This is a common issue which needs to be taken care of prior to the cylinder getting stuck or snaps off.
To unlock an ignition lock from a Mercedes that is locked position, apply a bit of pressure to the key while simultaneously turning the key. You should do this slowly and slowly, so as to not damage the lock mechanism or the key.
