Hi ,
Well actually quite often a lock turns out to be picked easier to the "wrong
direction" then the direction you're aiming for.
When one direction doesn't work, you should ALWAYS try the
other direction as well !
Once successfully picked in the unwanted direction, you can revert the
situation with a so-called "plug spinner".
This springloaded device will turn the lock so fast that
the springs have no time to push the pins back into their holes.
Result : A picked lock, to the right direction
A plug spinner is also very handy, for a lock that needs
to be rotated more than once to fully unlock.
Otherwise you would need to re-pick it for every rotation.
