How to write a program for a car engine?

Question

Programming

Good afternoon. Recently I saw how my grandfather was tinkering with a laptop in a car engine. In the sense of a program for diagnostics and a lot of things ... It's very interesting in what language they are implemented. As a child, I heard that cool cars are stolen with the help of "such" programs. Is it really enough to have an "array key"=) to steal a ferrari?
