How to Make a RollJam?

Hi everyone,

Since a few weeks I search a tuto in order to make a RollJam car hacking for trying on my car to see if it's really working (here: http://thehackernews.com/2015/08/rolljam-unlock-car-garage.html)

If somebody know how to make it, please send me the link, thanks a lot!
