Your Ford F 150  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 explain what this famous immobilizer is for and just how it works on your Ford F 150 .find-anti-start-code-ford-f-150 

Anti-start utility on your Ford F 150 :

This one is as expected used as an anti-theft protection. Indeed, it is programmed to be able to start your Ford F 150  exclusively if the key that has this code is inserted. We keep in mind 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 F 150 :

To put it simply, we have a transmitter and a receiver that work together to validate the operation and consequently switch on the engine. The immobilizer has the transmitter, and will therefore issue a code request when the key is inserted in your Ford F 150 . 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 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 let the engine start.
The procedure 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 deal with on your Ford F 150 .

Immobilizer failures:

There may be various motives that prevent your Ford F 150  from starting because of the immobilizer. First of all, stupidly, you’re not using the right key. It may seem not important but it happens!
If you have the right key, you have two options left:

  • Option n1: The transmitter is involved, consequently the immobilizer. In this case, it is easy to identify if you have a duplicate key. If, with the two keys of your Ford F 150 , you have the same difficulty, 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 subjected to 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 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 Ford F 150  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 send out the code to you. You must send your car.


  • – First try to find where the failure on your Ford F 150  came from. Then act accordingly. It would be a pity 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.
