Some of the keys are SO hard to get (unless you are a certain sort of thief) That it takes a group of five. Then you copy the key and start gathering, but that group of five is still going to want a cut of that knowing damn good and well why you copied that key. So a good chunk of your earnings go to the group that helped you get the key. At least with Durble/Sylos that was the case. I actualy prefered how I got it with Armagon to locksmithing a key anyday.
