Lock blocks after 180° rotation

[Blackliquid]

Hi everyone! I was just picking one of my practise locks and it happened again. After i sucessfully picked the lock, the cylinder did half a rotation and suddenly blocked.
This problem happed to me already with 2 locks ( one of them is mounted in a door). Im pretty sure it has nothing to do with the other part of the lock wich pushs the lock bar (?) since it happens with with an unmounted lock too. With the unmounted one i can sometimes solve with a couple of rakes, then its free to turn further, but i didnt manage this on the lock mounted on the door, since it's harder to pick. This doesnt happen with a key.

This is really annoying, anyone already had countered this problem and maybe found the source/ solved it? (Didnt find anything with the search function)

Doh! Have you thought about doing a search, there are mountains of posts directly related to your subject.

oops my bad

the driver pins have dropped into the bottom of the plug. Just lift them with a pick and continue turning.

I looked up "stuck" and got this:

We've all been there, and we all asked this question, but yeah, search is your friend because it's been answered so many times in the last 5 years.

Welcome to hobby lockpicking, and remember to keep it legal and ethical, and only pick your own locks and not locks that are mounted on your front door, dorm room, apartment door, etc, as things can happen and then you get your self in a jam.

Good eye! wanna know why? the key occupies the entire keyhole during the rotation of the plug. If you go to howstuffworks.com or to youtube and look up lock animations you'll notice there are pins that the key pushes up, which then lift some other pins out of the way, and all of this is under spring pressure from little springs in each pin chamber. When you pick a lock and rotate it 180 degrees, with no key, the spring loaded pins inside the shell are going to want to come out and play and they will shoot out into the empty keyway because there is no key to stop them. This immediately makes rotation stop in that position, until you stick a pick in there and lift them all up while continuing to rotate the plug.

Check out that post I linked to, it will explain everything with very nice photographs.

Hello Squelch. First, im sorry, i know how annoying it is to be asked the same question by noobs over and over since i have some experience with online forums (go sticky the thread ).
Second, since i already dissasembled an euro lock, so i immediatly understood what u were saying. So this is due the fact that on the opposite pin side the cylinder is opened (which permits us to repin a lock e.g.), the driver pins push up into the groove due to the spring pressure, why didnt i think of this before ><

Also, the mounted lock wasnt in use, well not really (inside door which is never locked anyways) so i didnt break the golden rule of "never pick a lock you rely on" (yeah, ive read the stickes ).

P.S. :

[...] come out and play [...]

the funniest is that a simple search between two foreign degree symbols created this new thread.

why is my lock stuck 180'

Lock blocks after 180° rotation

see, we wouldn't have had to use specific words. interesting two thread combo, plus one magic for that.
