Thanks for the suggestions. I've already dabbled into lockpicking as a hobby. I honestly have no idea what you are talking about with the last sentence though. Are you making a joke about the likeliness of making a career in pentesting? Or is this a way of describing how to infiltrate a building by running a long-con as one of their janitorial staff...
That last route threw me off at first as well. But it does provide excellent cover and who would suspect a simple janitor of anything. An added benefit is you get a key to almost anywhere.
