Your Toyota Corolla doesn’t start anymore and you know 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 describe what this famous immobilizer is for and how it works on your Toyota Corolla.find-anti-start-code-toyota-corolla

Anti-start utility on your Toyota Corolla:

This tool is of course used as an anti-theft protection. Indeed, it is programmed in order to start your Toyota Corolla exclusively if the key containing this code is inserted. We keep in mind these films where thieves adjust a few wires under the dashboard to start the engine, which is impossible with the anti-start system.

Anti-start operation on your Toyota Corolla:

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 Toyota Corolla. Think of this transmitter as a doorkeeper who would ask for an entry code when someone knocked at the door.
This code request is provided to the key, which subsequently, 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 Toyota Corolla.

Immobilizer failures:

There may be various reasons that prevent your Toyota Corolla from starting because of the immobilizer. First of all, incredibly, 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. Usually, it is easy to detect if you have a duplicate key. If, with the two keys of your Toyota Corolla, you have the same difficulty, then it is the anti-start that is flawed 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 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 Toyota Corolla 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.

Conclusion

  • – First try to identify where the failure on your Toyota Corolla came from. Then act accordingly. It would be a shame to replace 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.
