When it comes to your car, you want to make sure that itโs always ready for anything. And one of the most important components you need to keep an eye on is the ignition switch.
The ignition system in your vehicle is made up of two parts – the ignition lock cylinder and the ignition switch. The switch is located on the steering column just behind the lock cylinder. These two parts work together to turn on the vehicle and start it up.
You can find more information about your vehicleโs system by checking your ownerโs manual or asking your mechanic for help.
Ignition switches usually have three positions that provide power to different systems as the key is turned. Most of the time, the first position will activate electrical accessories, the second position will power on the fuel and ignition systems, and the third position will crank the engine.
If you own a Mercedes, chances are youโre probably overall pleased with it; however, just like any other car or machine, things tend to wear out and require replacement over time. Thatโs why itโs important to know what to do when your Mercedes starts to show signs of wear and tearโand how to keep your vehicle in good shape for as long as possible.
If youโve recently purchased a Mercedes, you may be wondering why the ignition key doesnโt work. After all, thatโs what itโs there for: to start up the car.
Unfortunately, some Mercedes drivers have reported issues with their ignition keys in the past. Although, with recent developments in technology, ignition keys have begun to be phased out and replaced with keyless entries, remotes, and key fobs.
If you think your Mercedes key ignition is not working properly, but you canโt make sure if it is actually troubling, then here are a few symptoms to know that show that your Mercedes is actually having trouble with the ignition key.
Common Symptoms of a Faulty Ignition Key in a Mercedes
1. Car stalls while driving
If youโre having problems with your ignition system, itโs important to know that there are multiple symptoms of a problem. Sometimes, the most frustrating thing about your car is when it will just stop running. Itโs not a matter of if your car will stop running. And if youโre like most drivers, youโve had to deal with this problem more than once.
What causes your car to suddenly stall? The most common reason is a failed ignition switch or a faulty alternator. If either of these things fails while youโre driving, your engine will cut off power from the ignition and fuel systems, which causes it to stall.
Depending on what issue was causing the issue, however, your Mercedes may or may not restart a short while later.
2. Issues turning or removing the key
If the ignition key on your car gets stuck, it could be a sign of a worn-out ignition switch. This is a common issue with all cars, but in some cases, it can become so severe that the engine will continue running even after youโve removed the key.
If your vehicleโs ignition switch has been acting up lately and wonโt reset properly or cause your key to get stuck, itโs probably time to replace it! The key isnโt connected to the switch properly, causing unnecessary wear and tear on both components. A worn-out switch can also lead to other problems with your carโs engineโespecially if youโve already replaced a starter or found other issues with your vehicleโs electrical system.
When your car starts and then suddenly stalls, it could be a sign that the ignition switch is failing.
The ignition switch is what helps to provide power to your fuel and ignition systems when you turn on your vehicle.
If the ignition switch fails in one position, it could cause the car to start and then stall immediately.
This switch is responsible for cutting off power to the fuel and ignition systems if the engine fails to start. Without it, the engine would continue to draw fuel and create a spark, which could cause a fire.
If this is happening to you, donโt ignore it! A professional technician can help determine if your ignition switch should be replaced.
3. Issues powering on the accessories
The ignition switch is an electrical device that allows you to turn your car on and off. When the key is inserted into the ignition, it powers the carโs engine and accessories. If the key is turned to the โaccโ position and none of the accessories are powering on, this could be a sign of a faulty ignition switch or lock cylinder.
If youโre experiencing any of the above symptoms, itโs highly recommended that you bring your vehicle in to get it properly diagnosed by a professional. Fuse and wiring issues can oftentimes be the culprit, so itโs best to rule those out as potential causes.
4. The engine does not start
If your car isnโt starting, it could be due to a bad ignition switch. The ignition switch transfer power to the engine controls, starter motor, and ignition controls. The engine may not receive the power which is required to start up if the ignition switch isnโt working properly. An engine not starting could be one of them.
If youโre experiencing this issue, itโs best to have an expert at your disposal who can diagnose the problem and get your car back on the road as soon as possible!
