Spring wrapped around cylinder

[Jburgett2nd]

I got this kwikset from a guy that was trying to rekey it, told me it was broken and that keys got stuck in it and it would not rotate all the way, so I take it apart and find that one of the springs somehow got wrapped around the cylinder, never heard about it before, guessing im not the only person that has run into this. here are some photos the only thing I can think of how this would happen is the guy put in a spring but no top pin. I can tell you this much getting that cylinder out was a pain in the neck!

I just did this to a lock the other day.

I picked the lock, turned the cylinder over without anything in the keyway. This dropped a short pin into the keyway (never found it for some reason). I thought I pushed all the pins back up and turned the lock back, but the end of the spring dropped into the bottom of the keyway. Buggered it up real good when I turned it back.

Gotta hate those disappearing pins, swear sometimes scotty must be beaming them up into the enterprise.

This also happens in locks with short driver pins - if you get a short driver and short key pin you can pick the stack so that both key and driver pins are below the shear line, and the spring above it. When you turn the plug the spring gets caught and is dragged around the plug.

IMO this is a design flaw, but I've encountered it in quite a few factory pinged locks, particularly eurospec MP10 locks which use a very short driver in their 1109 cylinders.

Since he was rekeying it, probably happened like mhole mentioned. Short key pin and short driver pin. Tell him that nobody you know of has ever done that before. Especially not little old me.

My Master M930 is now pinned with American serrated key pins and drivers because of a little snafu that resulted in three springs wrapped around the plug and half the pins missing. Turns out, when you drop a few key pins out of the plug and onto carpet without realizing it, then reassemble...well, bad things happen.

I did this once while picking a master keyed Medeco on a door at work. The lock was in use and I spent the rest of the evening taking it apart and fixing it and making sure all the needed keys still operated in it and had to scavenge a spring from another Medeco.

That's one of the biggest reasons I'm so quick to tell new members not to pick locks in use.. things happen.

That's really funny, because I just did the same thing a couple days ago. I'm making a progressive padlock set out of some American 1100s, and I lost a top pin without realizing it. I thought I was going to have to throw the whole lock out.
