1. A clamshell style gunlock having a magnetic shield comprising:

  • a first portion, said first portion including a first hinge component;

    a body portion including a second hinge component configured for cooperatively engaging with the first hinge component of said first portion, for allowing at least said first portion to move pivotably with respect to said body portion;

    at least one of said first portion and said body portion including a locking mechanism, said at least one of said first portion and said body portion including said locking mechanism constructed of a non-magnetically conductive material, said locking mechanism including a spring loaded pin mechanism configured, in a first position, for preventing said first portion or said body portion from moving pivotably with respect to the other of said first portion and said body portion;

    an electro-mechanical device disposed in said at least one of said first portion and said body portion including said locking mechanism, said electro-mechanical device coupled to said locking mechanism and responsive to at least one of electrical activation and activation from a magnetic field of sufficient magnitude to activate said electro-mechanical device, said activated electro-mechanical device configured for operatively causing said spring loaded pin mechanism of said locking mechanism to move from said first position to a second position, wherein said second position allows one of said first portion or said body portion to move pivotably with respect to the other of said first portion and said body portion; and

    a magnetically conductive shield, disposed proximate said electro-mechanical device, and configured for shielding an externally provided magnetic field from acting on and activating said electro-mechanical device and operatively causing said spring loaded pin mechanism of said locking mechanism to move from said first position to a second position, by sufficiently disbursing any magnetic forces from the magnetic field of the magnet or other magnetic field producing device away from the electro-mechanical device.
