Your Mercedes Benz GLC Class doesn’t start anymore and you understand it’s because of your immobilizer but you don’t know specifically how it works or how to find it? We will try to provide you with an answer in this article.
First, we will describe what this famous immobilizer is for and how it works on your Mercedes Benz GLC Class.
Anti-start utility on your Mercedes Benz GLC Class:
This one is as expected used as an anti-theft protection. Indeed, it is programmed to be able to start your Mercedes Benz GLC Class only if the key containing this code is inserted. We think of these movies where thieves manipulate a few wires under the dashboard to start the engine, which is very unlikely with the anti-start system.
Anti-start operation on your Mercedes Benz GLC Class:
To put it simply, we have a transmitter and a receiver that work together to validate the operation and as a result switch on the engine. The immobilizer provides the transmitter, and will consequently issue a code request when the key is inserted in your Mercedes Benz GLC Class. Think of this transmitter as a doorkeeper who would ask for an entry code when someone knocked at the door.
This code request is directed to the key, which subsequently, sends a unique user code, specific to the start system, and if this code matches, then the anti-start will make the engine start.
The operation is very simple. However, when mentionning double safety, we also imply potentially more possibilities of breakdowns or various failures unfortunately.
In the next paragraph, you will find the various breakdowns you could face on your Mercedes Benz GLC Class.
There may be various motives that prevent your Mercedes Benz GLC Class from starting because of the immobilizer. First of all, incredibly, you’re not using the right key. It may seem superficial but it happens!
If you have the right key, you have two options left:
- Option n1: The transmitter is involved, so the immobilizer. In such a case, it is easy to identify if you have a duplicate key. If, with the two keys of your Mercedes Benz GLC Class, you have the same difficulty, then it is the anti-start that is faulty and therefore must be replaced or disabled. Doing so will cost less than replacing it, but your car will be more exposed to theft and your insurance may not cover you if your car is stolen.
- Option n2: The difficulty comes from the receiver, the key, which transponder has been broken. This can be changed for less money by a professional than the anti-start system.
If you speak to your mechanic, he will obviously offer to tow your Mercedes Benz GLC Class and charge a high price for everything, he will not give you the code easily. For security reasons alone, it is legally impossible to transmit the code to you. You must send your car.
- – First try to find where the failure on your Mercedes Benz GLC Class came from. Then act accordingly. It would be a pity to change the entire immobilizer system when the key is defective.
- – Make a quote at a garage and then consider an replacement at an online professional, which will often be more efficient and less expensive.
