Cutaway view of "Hung" top pins

[whiteknight38]

The problem of a picked plug turning only 1/2 way around, and "locking up" in the upside down position has been addressed in a few posts, but some of you noobs might like to see a cutaway I made to illustrate the point.
The first pic shows how a key normally forms a "bridge" to fill the split bottom of the plug, but the second image illustrates how one or more upper pins sometimes get caught in the gap, which locks up the plug.

It's not a super common problem, but happens often enough in the field, that you have to be aware of it, (and the solution,) to insert a flat pick or wrench handle, all the way into the keyway, and loosen and lift the offending pins, while you complete the turn.

Ugly problem.

Beautiful photography.

Try holding something in front of your flash, it'll be even better.

Cheers.

I remember when i first started picking i purchased a kwikset cutaway practice lock and it did this to me the first time i used it. I ended up destroying the lock because i didnt know what happened.

What caused it to be destroyed?

Nice job man I find it always helps me to understand things when I can visualize them. That cutaway certainley does a good job of that. I'm sure this post will be a great help to beginners. Keep it up.

Why in it on a key chain?
Easy access if you have to explain to someone?

Good eye iTago. It is indeed on a key ring, on a hole drilled into the last (empty) chamber. Obviously, this is the number one chamber for this unique purpose. The ring holds the appropriate key for this demo lock to keep it handy.
I'll usually drill out the empty number-five or 6-stack to attach a key, (or a laminated post-it note) on any particular KIK lock that is especially interesting for one reason or another. The notes might refer to a particular picking sequence, ie. 3-PIN Picks 3-1-2 CCW (soft tension) Moderate difficulty.
