Your Ford Fusion 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 describe what this famous immobilizer is for and just how it works on your Ford Fusion.find-anti-start-code-ford-fusion

Anti-start utility on your Ford Fusion:

This one is as expected used as an anti-theft protection. Indeed, it is programmed to be able to start your Ford Fusion exclusively if the key that has this code is inserted. We think of these films where thieves operate a few wires under the dashboard to start the engine, which is impossible with the anti-start system.

Anti-start operation on your Ford Fusion:

To put it simply, we have a transmitter and a receiver that function 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 Ford Fusion. Imagine this transmitter as a doorkeeper who would ask for an a way in code when someone knocked at the door.
This code request is sent to the key, which in turn, sends a unique user code, specific to the start system, and in the event 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 chances of breakdowns or various failures unfortunately.
In the next paragraph, you will find the various breakdowns you could deal with on your Ford Fusion.

Immobilizer failures:

There may be various factors that prevent your Ford Fusion 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, consequently the immobilizer. In such a case, it is easy to detect if you have a duplicate key. If, with the two keys of your Ford Fusion, 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 replaced for less money by a professional than the anti-start system.

If you get in touch with your mechanic, he will obviously offer to tow your Ford Fusion 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 Ford Fusion 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.
