What is it?
KineticDefence™ is a technology that will be added to Lockwood 5 pin tumbler cylinders preventing “bump” attack.
A unique set of stainless steel driver pins, along with tight manufacturing tolerances increases the security of the cylinder by resisting bump and picking manipulation. These stainless steel driver pins have a unique geometry which resists the kinetic forces applied when under a “bump” attack. Bumping” is a method of transferring energy to the internal pin tumblers to separate the pin sets while a rotational force is applied to defeat the cylinder. Awareness of the method of bump attack on pin tumbler cylinders has increased with information shared on the internet sites such as YouTube.”
This method of attack can be best explained using the Newton Cradle as an example. Newton’s Cradle has a number of beads suspended and touching each other. If one of the beads are separated and released the kinetic energy is transferred through the other beads resulting in the end bead on the end of the line to separate and move away from the bead set. The reaction of the pin tumblers inside the cylinder is similar when under a “bump” attack using a specialised key.
