Pick resistant pin tumbler lock

A pin tumbler lock apparatus, comprising:

• a) a shell;
• b) a gate located within the shell, the gate comprising a cylindrical case, a first plurality of bores along its top and a second plurality of bores along its bottom;
• c) a core rotatably disposed within the gate and defining a keyway, a third plurality of bores along a top of the core and a fourth plurality of bores along a bottom of the core, wherein the third and fourth plurality of bores communicate with the keyway through the core and that, in the locked position, communicate with corresponding bores of the first and second plurality of bores in the gate to define a plurality of pin chambers;
• d) a plurality of magnetically activated key pins that are moveable within the pin chambers against magnetic activation by a key inserted in the keyway through a keyhole into a position wherein the core can be rotated relative to the gate;
• e) wherein each key pin comprises a body and a top element with a diameter larger than a diameter of the body, and wherein each key pin has a height randomly selected from a bitting range;
• and
• f) the gate further comprising a plurality of channels corresponding to the plurality of pin chambers, wherein when the key is inserted into the keyway and the core rotates relative to the gate, the top element of each key pin moves within a respective one of the plurality of channels.
