A lock assembly including a plurality of button assemblies having a plurality of indicator elements. A position of the indicator elements sets a lock combination. A code blocker is configured to cover and prevent access to the plurality of button assemblies when the lock assembly is in a first position, for example in an unlocked position, and to allow access to the plurality of button assemblies when the lock assembly is in a second position, for example in a locked position.

A lock is provided, the lock having: a lock mechanism having a first member and a second member, the first member and the second member each being slidably mounted to a housing of the combination lock, wherein the first member is capable of movement between a first position and a second position and the second member is capable of movement between a first position and a second position and wherein movement of the first member from the first position to the second position causes the second member to move from the first position to the second position; a bolt configured for movement between a locking position and an unlocking position, the bolt preventing the second member from moving from the second position to the first position when the bolt is in the locking position.

An environment friendly metal mechanical password lock cylinder capable of setting repeatedly password keys comprises password rebound leaves, a label panel, a fastener locking plate, a positioning plate, a fastener reset plate, an axis panel and a control plate. The label panel is fixedly connected with the positioning plate; the fastener locking plate is disposed between the label panel and the positioning plate; the fastener reset plate is slideably disposed on the positioning plate; the axis panel is matched and connected with the label panel; the control plate is slideably disposed on the axis panel; the password rebound leaf runs through the label panel and the positioning plate in sequence and corresponds to the control plate; the number of the password rebound leaves is set to be several; and at least one password rebound leaf in the plurality of password rebound leaves is provided with positioning blocks matched with the control plate.

A resettable combination lock mechanism includes a plurality of outer lock dials and a plurality of inner lock dials. The rotation of a reset feature changes the relative axial position between the outer lock dials and the inner lock dials, allowing the combination of the lock mechanism to be reset. In one aspect, the outer lock dials are axially displaced upon rotation of the reset feature, exposing a visual indicator that is configured to indicate whether the lock is in a combination reset mode or is in a normal mode. The reset mode allows the combination to be changed. The normal mode allows the lock mechanism to be locked or unlocked to secure or release a desired item. In another aspect, the rotation of the reset feature rotates a visual indicator into alignment with a window to indicate that the lock is the reset mode or the normal mode.
