“that whenever the parts of a lock which come in contact with the key are so affected by any pressure applied to the bolt, or to that portion of the lock by which the bolt is withdrawn, as to indicate the points of resistance to the withdrawal of the bolt, such a lock can be picked.\u201d<\/strong> Alfred Charles HOBBS.<\/p>\n\n\n\n

How it works ?<\/h2>\n\n\n\n
<\/div>\n\n\n\n

Tolerances vary depending of the lock manufacturers. The main reason that a lock can be picked is due to a sum of an accumulation of imperfections in their production methods, some voluntary mechanical tolerances and lock’s design.<\/p>\n\n\n\n

\n\n\n\n

Les tol\u00e9rances varient selon les fabricants. La principale raison qu’une serrure peut \u00eatre crochet\u00e9e est due \u00e0 une accumulation d’imperfections au niveau des m\u00e9thodes de production, des jeux m\u00e9caniques de fonctionnement et de la conception de la serrure.<\/span><\/em><\/p>\n\n\n\n

All driver pins bind simultaneously<\/em>.<\/figcaption><\/figure><\/div>\n\n\n\n

So when we put a rotaring tension on the plug, driver pins is sheared at the space between the plug and the shell named the shearline. Driver pins bind and results a friction proportional to the torque force. If the alignment of all pin’s chambers is perfect with no any defaults, then driver pins will bind simultaneously and the friction will be the same on each pins.<\/p>\n\n\n\n

In the reality, manufacturers tends to reduce their production tolerances but the alignment of each chamber and pin’s geometry will remain imperfect despite the machining excellence of some manufacturers.<\/p>\n\n\n\n

\n\n\n\n

Ainsi, quand on exerce une tension rotative sur le rotor, les contre-goupilles sont cisaill\u00e9s au niveau de la s\u00e9paration du rotor et du stator appel\u00e9e ligne de c\u00e9sure. Les contre-goupilles sont contraintes et il en r\u00e9sulte une friction proportionnelle \u00e0 la force de couple. Si l’alignement des logements des goupilles est parfait sans aucun d\u00e9fauts, alors les contre-goupilles seront cisaill\u00e9es simultan\u00e9ment et la friction sera la m\u00eame sur chaque goupille.<\/span><\/em><\/p>\n\n\n\n

En r\u00e9alit\u00e9, les fabricants ont tendance \u00e0 r\u00e9duire les tol\u00e9rances mais l’alignement des per\u00e7ages et la g\u00e9om\u00e9trie des goupilles resteront imparfait malgr\u00e9 l’excellence d’usinage de certains fabricants.<\/span><\/em><\/p>\n\n\n\n

With a proper light tension, a driver pin (red) will bind more than the other pins and transmit its resistance to its key pin (blue). Your pick slighly touch this pin and jump up on it. It means that this pin is binding to tight and doesn’t want to move down. If you push down to pick this pin and rise it at the shearline, another pin will bind respecting to an order called “binding order”.<\/p>\n\n\n\n

\n\n\n\n

Avec une l\u00e9g\u00e8re tension, la contre-goupille (en rouge) sera plus contrainte que les autres et transmettra sa r\u00e9sistance \u00e0 sa goupille sup\u00e9rieure (en bleue). Votre palpeur effleure cette goupille et tressaute dessus. Cela signifie que cette goupille est trop contrainte et ne peut coulisser dans son logement. Si vous abaissez cette goupille \u00e0 l’aide du palpeur jusqu’\u00e0 mettre au passage sa c\u00e9sure, une autre goupille sera cisaill\u00e9e en respectant un ordre appel\u00e9 “l’ordre de placement”.<\/span><\/em><\/p>\n\n\n\n
