Here's the way I do it.
No pickle fork
No puller

No ****


Press on the little hidden thingy and wiggle the knob thingy till you
can get the shaft to drop.
Take the shaft and turn it upside down and put it down inside so it is
right on the end of the cylinder thingy.
Make sure there is room for the pop-out thingy to come out-hold the
key-knob thingy by the stem.
Now hit the other end of the shaft with a small ball-pien hammer-
Or invert the whole thingy, holding the shaft lightly and gently slam
it on a good hard surface.
POP.
Now you can reverse the cylinder thingy and put it back in so the
keyway will be right side up-or pins up.

All you have to do when you put it back together is nake sure the
little metal springy thingies are bent back to their original shape so
that they lock in good..
