There are other scenarios. Apparently (I do not own a car, so forgive my ignorance), it is possible now (at least above a certain price) to unlock your car remotely via smartphone or something. Imagine a criminial organization gaining access to a car manufacturer's network so they can steal cars. Some people apparently like the idea of being able to lock/unlock the front doors of their houses/apartments via smartphone app. I am not certain how this is more convenient than getting a key out of your pocket, but it doesn't matter - the same scenario applies. These are probably going to be "cloud"-based, so if someone can compromise the servers, they can now gain access to entire neighborhoods. (Or, alternatively, lock the doors, keep the people inside.)
