IF (I could be mistaken) it is the same system that Mercedes uses, then yes and no. There should be a sensor somewhere on the door handle that you have to put your thumb over. As long as the key fob is close enough to the car the doors should unlock when you touch it. The car will not, however, lock itself automatically. There used to be a link in the Mercedes Website that showed a demo of the system in action, but it is no longer there.
