I am starting to see more and more of these come on the market. It is pretty funny because my brother in law had one that was a different brand. My friend worked in a home improvement store and he knew all of the manufacturer codes for them. He was able to gain access to their house even though they had set a different code. We were all there though, nothing nefarious happening. Anyway, I wonder about the security of some of these. It seems like they all probably have some sort of "back door". Thanks for sharing!
