I think I agree that if your threat model is targeted, pre-meditated entry then going with a company that has never had any problem may be the way to go. I suspect that you've never visited a Timpson's, which are your general, run of the mill high-street key-cutter. You walk in with your keys, ask them to make copies, they cut them while you wait (and watch if you want), you walk out with your new keys. For most people that's pretty much fine whoever is cutting the keys as they don't know where you live. If you're paranoid and/or have threat models that include lots of things that your average man on the street doesn't have to worry about, then you should be cutting the keys yourself.
