Patent ID: 8082766

Claim:
A system for releasing a pin tumbler lock defined by a plug disposed within a casing, a series of aligned vertical holes formed within the plug and casing, spring-loaded driver pins and corresponding key pins disposed within the aligned holes such that the plug can be rotated relative to the casing when respective contact surfaces between the driver pins and key pins are aligned with a shear line between the plug and casing, a locking mechanism that releases upon relative rotation of the plug and casing, and a keyway horizontally formed within the plug, the system comprising: a lift, device for inserting into the keyway and urging the key pins and driver pins upward against their spring biases, wherein the lift device comprises: a handle; and a blade configured to insert horizontally into the keyway; a key device for inserting into the keyway horizontally adjacent the lift device, wherein the key device comprises: a handle; and a blade comprising a base with teeth projecting therefrom, wherein the key blade is configured to insert horizontally into the keyway, and the key teeth are configured to contact the key pins and to insert vertically into the plug holes; a shim device for inserting into the keyway underneath the key device and further urging the key pins and driver pins upward against their spring biases such that the key pins and driver pins are disposed outside the plug's periphery and respective contact surfaces between the key teeth and key pins are aligned with the shear line, the shim device comprising: a handle; and a blade configured to insert horizontally into the keyway; and wherein the plug is rotatable relative to the casing while the key blade and shim blade are horizontally inserted into the keyway and the key teeth are vertically inserted into the plug holes.
