It appears to enter the plug at a 45 degree angle relative to the key pins. I couldn't manage to take a photo of it, so I improvised a diagram from a picture of another lock from the 55/30 line. Location/size/orientation are approximate as staring down a keyway is not the best way to measure something.

I was asked if there were any features on the key, so I took a photo. Additionally, there's an adjusted version to better show the bitting of the key. (I believe that this lock has 3 pins, however, there are what look to be 4 cuts--and there's still the matter of that strange "pin" at the end.)


Anyone know what it is?
