Your Toyota RAV4 doesn’t start anymore and you know 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, we will explain what this famous immobilizer is for and just how it works on your Toyota RAV4.find-anti-start-code-toyota-rav4

Anti-start utility on your Toyota RAV4:

This one is of course used as an anti-theft protection. Indeed, it is programmed in order to start your Toyota RAV4 only 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 very unlikely with the anti-start system.

Anti-start operation on your Toyota RAV4:

To put it simply, we have a transmitter and a receiver that work 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 Toyota RAV4. 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 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 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 experience on your Toyota RAV4.

Immobilizer failures:

There may be various motives that prevent your Toyota RAV4 from starting because of the immobilizer. First of all, stupidly, 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 this case, it is easy to establish if you have a duplicate key. If, with the two keys of your Toyota RAV4, 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 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 Toyota RAV4 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 Toyota RAV4 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 alternative at an online professional, which will often be more efficient and less expensive.
