If you haven’t watched the videos on lock bumping, raking, and picking, do that first before reading the rest of this post. The executive summary is that unless you have expensive high security locks on your doors, the chances are that it’s really easy to unlock your lock without a key within seconds, and not leave a trace. But you really need to see how easy it is to believe it. When changing the locks on my house, I was wondering what I can do to make it harder to open them using a bump key. Turns out that you can cheaply modify off-the shelf deadbolt to be significantly harder to bump or pick.
