@xyz987: concerning Master Device Keys. I believe every "floor" in the garage has some kind of sub-Master Device Key and each of these keys is probably derived from a Master Device Key.

To be honest though there is not much to say or speculate about it than this. We simply don't know how they derive the Master Keys. And personally I don't think its very interesting since we can never find them out.

The only thing that matters is they have the ability to reach every Device and Processing Key.
