Claim 0:
1. A high security locking system comprising:
a key;
a lock housing;
a lock cylinder supported by the lock housing for rotation about a lock axis responsive to a torque applied to the lock cylinder;
a plurality of pins operatively associated with the lock housing and the lock cylinder for engagement by the key when the key is inserted into the lock housing for movement of the pins relative to the lock cylinder and the lock housing between a locked position blocking rotation of the lock cylinder relative to the lock housing and an unlocked position in which rotation of the lock cylinder relative to the lock housing is uninhibited by the pins;
a slider operatively associated with the lock housing and the lock cylinder for movement relative to the lock cylinder and the lock housing between La a cylinder locking position of the slider blocking rotation of the lock cylinder relative to the lock housing so as to isolate the pins from the torque applied to the lock cylinder while allowing the pins to be displaced between the locked and unlocked positions thereof and ii a pin locking position of the slider in which the pins are resisted from movement relative to the lock housing and the lock cylinder by the slider while rotation of the lock cylinder relative to the lock housing is uninhibited by the slider;
wherein the slider includes a first interlocking feature formed thereon for engaging at least one of the pins in the pin locking position of the slider; and
wherein said at least one of the pins includes a plurality of second interlocking features formed thereon at spaced apart positions along a length of the pin, in which each second interlocking feature is arranged to be interlocked with the first interlocking feature at a respective longitudinal position of the pin relative to the lock cylinder to resist movement of the pin relative to the lock cylinder.
