Your Hyundai Elantra 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 of all, we will explain what this famous immobilizer is for and just how it works on your Hyundai Elantra.
Anti-start utility on your Hyundai Elantra:
This one is as expected used as an anti-theft protection. Indeed, it is programmed in order to start your Hyundai Elantra only if the key containing this code is inserted. We remember these films where thieves operate a few wires under the dashboard to start the engine, which is out of the question with the anti-start system.
Anti-start operation on your Hyundai Elantra:
To put it simply, we have a transmitter and a receiver that function together to validate the operation and consequently switch on the engine. The immobilizer provides the transmitter, and will therefore issue a code request when the key is inserted in your Hyundai Elantra. Think of this transmitter as a doorkeeper who would ask for an a way in code when someone knocked at the door.
This code request is directed to the key, which in turn, sends a unique user code, specific to the start system, and assuming this code matches, then the anti-start will make the engine start.
The operation is very simple. However, when mentionning double safety, we also suggest potentially more possibilities of breakdowns or various failures unfortunately.
In the next paragraph, you will find the various breakdowns you could deal with on your Hyundai Elantra.
There may be various motives that prevent your Hyundai Elantra from starting because of the immobilizer. First of all, stupidly, 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 this case, it is easy to establish if you have a duplicate key. If, with the two keys of your Hyundai Elantra, you have the same problem, then it is the anti-start that is faulty and therefore must be replaced or disabled. Completing this task 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 problem comes from the receiver, the key, which transponder has been broken. This can be replaced for less money by a professional than the anti-start system.
If you contact your mechanic, he will obviously offer to tow your Hyundai Elantra and charge a high price for everything, he will not give you the code easily. For security reasons alone, it is legally impossible to send out the code to you. You must send your car.
- – First try to find where the failure on your Hyundai Elantra 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.
