However I believe that such an extrusion is apparently the weak point
with Euro cylinders. I don't know any more than that so hopefully
someone with more knowledge can confirm/deny this and explain further.

I heard of someone who had locked themselves out (after leaving by another
door with a latch bolt) and called a locksmith (another key was in the lock
on the inside). He filed a bit off the end of the key and it allowed the key
to then open the lock.

Any views on why this worked?
