What is the internal structure of the lock 'Enclave' that prevents picking with two levels of defense?
Cylinder locks, which can be opened with a jagged physical key, have one drawback: they can be easily opened by a skilled professional. A new shape has been devised to overcome that shortcoming.
A normal cylinder lock has several pins down from the outside of the cylinder to prevent the cylinder from rotating. If you insert the key here, the pin will be lifted along the shape of the key ...
You can turn the cylinder to unlock it. However, there is a problem that it can be unlocked without a key if there is a special tool and technique.
The picking method of unlocking with a tool usually pushes up the pin with a tool to find the position where it stops. At this time, Andrew Magill, who considered a new lock, had a problem with the fact that the position where the pin stopped was at a height that could be unlocked.
In the lock devised by Mr. Magill, the middle of the pin is finely sliced, and a part called 'top bar' that slides sideways is added to the top of the pin.
With conventional locks, the cylinder cannot be turned unless the pin is pushed up to the unlocked position, in other words, 'the lock can be unlocked if the cylinder turns'. However, this lock has pins sliced in multiple stages, so you can turn the cylinder wherever you like.
However, even if the cylinder turns, it cannot be unlocked unless the pin is in the correct position to pass the top bar. It cannot be unlocked unless the position is where the sliding parts can be passed. The animation that illustrates the unlocking with the correct key looks like this.
If you pick Magill's lock, you can lift the pin and get the feeling of 'stopping', but since the top bar is completely independent inside, 'Is the stopped position the correct unlocking position?' I don't know.
Therefore, although you can move the cylinder a little, you cannot move the top bar and you cannot unlock it. It is possible to accidentally push the pin up to a position where it can be unlocked, but since each of the 6 pins is sliced at 6 points in the middle, there are 46,656 combinations of pin positions.
Mr. Magill has applied for a patent for the lock he devised, and is selling handmade locks for feedback. YouTuber Lock Noob , who actually got the lock, tried picking and proved that it is still difficult to break through even if he knows the shape of the key.
