That key head is from a DOM RS System lock. It is a fairly standard (but reasonably high quality) pin-tumbler lock, with either 5 or 6 pins (RS5 or RS6). Assuming that your lock was factory-pinned, at least two of the drivers are typically spools, and at least two of the key pins are likely to be a sort of ball-like "mushroom" shape. That series does not, to the best of my knowledge, have any profile pins (active or passive).
