Key (lock)
A key is an instrument that is used to operate a lock. A typical key consists of two parts: the blade, which slides into the keyway of the lock and distinguishes between different keys, and the bow, which is left protruding so that torque can be applied by the user. The blade is usually intended to...

Lock bumping
Lock bumping is a lock picking technique for opening a pin tumbler lock using a specially crafted bump key. One bump key will work for all locks of the same type.-History:A US patent first appears in 1928 by H.R. Simpson called a "rapping" or bump-key...

resistant. The Bilock cylinder uses a patented locking system with two sidebars, 12 pins and 12 springs. In the New Generation Bilock a trigger pin has been added to increase security and extend the registered design of the product. The key design is a U shape profile with six cuts on each side of the key along with a central roller to activate the trigger pin in the front and center of the cylinder. In order for the lock

to operate, the key must be fully inserted, allowing the dual sidebars to enter the pins, provided the pins were raised to the correct height, thereby freeing the cylinder core for rotation. The cylinder does not use the traditional top and bottom pin combination, relying instead only on the holes in the side of the pins and pressure applied by the 12 springs above. Many pins have a dummy hole which will trap the sidebar pin if any turning pressure is applied to the lock with the pin in the incorrect position, preventing the lock from opening. Due to the lack of top pins, lock-bumping is theoretically impossible, because lock bumping requires a moment in time when the two pins separate and when this occurs and turning pressure is applied the cylinder will rotate, causing the lock to open, this bumping technique uses the principles of Newton's Cradle

Newton's cradle, named after Sir Isaac Newton, is a device that demonstrates conservation of momentum and energy via a series of swinging spheres. When one on the end is lifted and released, the resulting force travels through the line and pushes the last one upward...
