I guess the problem is the immobilizer does not recognize the key and the indicator light does not blink. Help me please! If you have the wiring diagram please send to me.

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.

Are you able to crank the engine? This guide will help us

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.

and to check the wiring.

Check out the diagrams (below).

Please let us know what you find. We are interested to see what it is.

Cheers, Ken
