This article fails to describe how easy/complex it is to steal those cars with this technology. You will need at least two people, plus some fancy electronics, plus you need to be close to the car's key fob. The latter part means that if the key fob is placed near the front door or a window it can be reached by the thieves. But if the key fob is placed more in the center of the house (assuming you're at home) the thieves are not able to get close enough to it to pick up its signals.
