Patent ID: 8094018

Claim:
A pick-resistant lock system comprising: a locking means comprising: a displacement sensor for sensing a displacement of an object so as to generate a displacement signal, the displacement sensor comprising: a micro electromechanical gyroscope, which generates the displacement signal when an angular velocity of the micro electromechanical gyroscope is larger than a predetermined threshold; a first counterpart; a first alarm; a first storage device storing an original displacement signal; and a first control unit receiving the displacement signal, starting the first alarm after comparing the displacement signal with the original displacement signal, and meanwhile transmitting the displacement signal to a second control unit; and a key comprising; a control switch; a second counterpart corresponding to the first counterpart for matching the key with the locking means; a second alarm; and the second control unit for receiving the displacement signal transmitted from the locking means so as to start the second alarm; wherein the locking means further comprises a first status indicator for indicating an actuating state, an off state, and a power shortage state of the locking means.
