An improved magnetic pin tumbler lock is controllable by magnetic attraction and repulsion in such a manner that the magnetic attraction or repulsion established due to the relative positions and polarity orientations of fixed magnetic pins placed in a plurality of pin bores arranged in line in the inside face of the lock cylinder, of movable magnetic pins slidably installed in pin bores to mate with the fixed magnetic pins, and of magnetic pieces provided in the key to be inserted through the key slot located at the center of the lock plug allow locking and unlocking of the lock. Non-magnetic pieces are associated with the movable magnetic pins and tread the shear line represented by a boundary line between the cylinder and the plug when the lock is locked.
