My car won't start, the key fob works only manually, when inserted the seat moves closer to the steering wheel, only the radio turns black when trying to crank but it doesn't make any noise. replaced the battery checked all the fuses, checked ground points, still no luck...

Hello,

This could be due to a faulty ignition switch lock cylinder.
Worn components inside the ignition switch can cause it to lose contact when you try to start it.
This typically leads to no crank no sound while trying to start.

Also, you want to make sure that the starter is getting power. No power to the starter can be due to a bad switch or wiring issue.
It might be a good idea to apply 12V power to the starter to see if that cranks over.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
