Your Hyundai Genesis doesn’t start anymore and you understand it’s because of your immobilizer but you don’t know particularly 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 how it works on your Hyundai Genesis.


Anti-start utility on your Hyundai Genesis:

This tool is as expected used as an anti-theft protection. Indeed, it is programmed in order to start your Hyundai Genesis exclusively if the key which includes this code is inserted. We remember these films 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 Hyundai Genesis:

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 has the transmitter, and will consequently issue a code request when the key is inserted in your Hyundai Genesis. Imagine 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 in turn, sends a unique user code, specific to the start system, and assuming this code matches, then the anti-start will let the engine start.
The procedure 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 experience on your Hyundai Genesis.

Immobilizer failures:

There may be various factors that prevent your Hyundai Genesis from starting because of the immobilizer. First of all, incredibly, you’re not using the right key. It may seem trivial 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 Hyundai Genesis, you have the same problem, then it is the anti-start that is flawed 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 problem comes from the receiver, the key, which transponder has been damaged. 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 Genesis and charge a high price for everything, he will not give you the code quite readily. 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 Hyundai Genesis came from. Then act accordingly. It would be a shame to change the entire immobilizer system when the key is defective.
  • – Make a estimate at a garage and then consider an replacement at an online professional, which will often be more efficient and less expensive.
