Erik, I don't know what this means, but I asked the locksmith about bumping and he said it is a lot harder than it looks. They have bump resistant locks which probably cost more. I have seen those videos too and it sure looks easy. Do they have bump keys for all the different locks? Wouldn't the bump key have to fit into the lock to start with? As I understand it you are trying to slow the bad guy down so he gets scared or nervous and moves on.
