Claim 13:
14. The security device according to claim 13
wherein the master blade forms a hollow storage structure that contains the first arm blade and the second arm blade;
wherein the first arm blade and the second arm blade are rotated into the hollow storage structure of the master blade as the master blade of the key structure inserts into the locking structure;
wherein the master blade interacts with the lock control circuit once the master blade is fully inserted into the locking structure;
wherein the first arm blade rotates away from the master blade after the master blade is fully inserted into the locking structure;
wherein the first arm blade rotates away from the master blade into a position that allows the first arm blade to interact with the lock control circuit;
wherein the second arm blade rotates away from the master blade after the master blade is fully inserted into the locking structure;
wherein the second arm blade rotates away from the master blade into a position that allows the second arm blade to interact with the lock control circuit;
wherein the second arm blade rotates away from the master blade in the direction opposite to the direction of rotation of the first arm blade;
wherein by the direction opposite to the direction of rotation of the first arm blade is meant that: a) second arm blade will rotate in the counterclockwise direction if the first arm blade rotates in the clockwise direction; and, b) the second arm blade will rotate in the clockwise direction if the first arm blade rotates in the counterclockwise direction;
wherein the first arm blade rotates back into the hollow storage structure of the master blade as the key structure is removed from the locking structure;
wherein the second arm blade rotates back into the hollow storage structure of the master blade as the key structure is removed from the locking structure.
