How does the Push Start work on Ferrari's?

I've seen in magazines the new Ferrari ITALIA 458, If someone left their 458 unlocked and went somewhere, then someone else went in the car and push stated it, would it work? Or is there a key you need?|||I have read info on some car's websites, but it was not for this Ferrari. There is a remote key, when you have it in your pocket and get inside the car, the car will recognize you as the driver and the car will be turned on. I just wonder if this car uses the same technologies as the other cars I have read.
