ABSTRACT:
A combination lock comprises a first shackle, dials, a spring loaded member biased against the innermost dial, a second shackle comprising an inner arm, a moveable block pivotably coupled to the inner arm and including a spring and an opposite T-shaped slot, and a key opening mechanism aligned with the moveable block and comprising a shaft and a cross member. Inserting a key into the mechanism and turning the key will rotate the shaft and the cross member until the cross member is aligned with an opening of the slot such that pressing the second shackle will cause the inner arm to counterclockwise pivot about the member, move the moveable block outwards to compress the spring and dispose the cross member in the opening, and disengage the second shackle from the first shackle.
