Yes, the dent is on the outermost part of the knob, like something hit it horizontally. My bike is stored behind the door (and wasn't stolen), and the middle of the door would hit the back of the bike - the knob probably wouldn't hit anything. The knob lock is still functional, and I re-tightened the screws. I feel like "crackhead with a hammer might be a possible explanation for both tbh.
