2006 Alfa Romeo 155 s V12

Dear sir,

i want to have an idea about one of thing i am planning to do...

i am thinking to design an electrical circuit which has got a facility that whenever i want to switch off the car and lock the door, and once i removed the key from the door, i want the windows by themselves to go up and turn off.

i want to know what items i may need and generally how such circuit can be designed
