the problem is the immobilizer does not recognize the key?

If it is an immobilizer fault, the wiring diagram is not going to help you. You need to find out what is causing the non starting. A diagnostic scan would assist in getting some additional information.

KHLOW2008 Thanks for your explanation. Do you know where can I find 2016 Toyota Corolla maintenance manual?

Hello,

I will give you what every your need for your car. Here is the wiring diagram for the security system. I noticed there are many fuses if you look at the wiring diagram you can see them all so I would start by checking them first.
