In 2015, Canadian engineer Ryan Bowley introduced the world to the concept of the Bowley Lock, which eliminates the possibility of using standard lockpicks to open the device. A little time passed and the inventor is ready to start producing a commercial version of his brainchild, for which he launched a startup. So what is so special about Bowley Castles?
It is based on the classic design of a cylinder lock, in which the unlocking occurs when all the pins of the larva come into contact with the relief pattern of the grooves on the key. And there is no particular problem simply to fill the space with a suitable material, insert a pick to lock the pins and open the lock. Therefore, Bowley hid the "check mechanism" deep in the bowels of the structure and designed a special key.
The grooves on the key perform the same function as before, but now there is a long slot. It serves for contact with the guide rail, along which the key turns in a certain position until the grooves are opposite the pins. It is impossible to get close to them in any other way, therefore it is unrealistic to open such a lock with ordinary master keys - it is easier to break out the whole larva.
The inventor modified the design of the lock by adding a second row of grooves and pins and making the key double-sided. The updated model 543 uses the same principle, but now there are not 5, but 9 pins, so copying the key will be much more difficult. Buyers are free to choose between a lightweight aluminum version and a premium stainless steel version with protective plates. Price: $ 137-174 per piece.
