A while ago I got a Smart ignition from a friend. Yesterday I got a key made for it and cleaned it a little (not perfect, but good enough )
Here it is with the plug removed:
This lock, not being attached to anything, has a loose plug (no pun intended ), as it comes out just by turning it upside down.
On the second image you see a little lever, it's the piece that holds the plug in place when installed in a car, but still let's it rotate if not fully pressed (I believe that has to do with how the lock interacts with the housing itself, but not sure).
Anyway, it's a 7wafer (4top/3down) lock with serrated wafer AND countermilled plug
Not the easiest to pick, but pickable, the feedback isn't very clear on this one
Hope you guys enjoy it!
