An illustrated door latch tool for externally unlatching a door latch. The door latch tool is useful when an emergency or other event occurs that requires entry into a room that has the door barred by the door latch. This door latch tool is useful for police officers, security officials, hotels, parents, etc. when there is a need to render aid to a person in the room or to aid in removing the person from the room and from any potential danger. The door latch tool has a card and a holder. When an event occurs and the door has a door latch locking the door, then the door is opened to its further point. The door latch tool is placed inside an opening of the door at the height of the door latch. The holder is held to maintain the placement of the door latch tool. The door is closed, thus the door latch tool aides in releasing the door latch such that the door may now be opened.

An inflatable air wedge has a tool channel that is inserted between a vehicle door and a vehicle body for allowing an operator to effectively unlock the vehicle door without damaging the vehicle (door and/or body and/or weather stripping). The inflatable air wedge includes a selectively inflatable bladder capable of being intercalated between the existing vehicle door and the existing vehicle body, a pneumatic mechanism in operable communication with the bladder for selectively introducing and releasing air from the bladder, and a conduit engaged with the bladder. Advantageously, such a conduit is suitably sized and shaped for guiding an existing unlocking tool therethrough while the bladder is at an inflated state and seated between the vehicle door and the vehicle body. Notably, the conduit is spaced from the pneumatic mechanism and manually distended when the unlocking tool is positioned therein.

A digital key management system for physical keys is provided. A processor registers a physical lock. A processor generates a digital key based on a physical key structure to be used with the physical lock. A processor configures the physical lock to decode an inserted physical key. A processor verifies the inserted physical key, in response to a digital key for the decoded physical key matching the generated digital key.

The combination padlock is of the type having a shackle, a dial for rotating a drive cam having a gate slot, a plurality of rotatable wheels or tumblers each with gate slots, and a fence for allowing the shackle to be opened when all of the gate slots are aligned with the fence. In carrying out the method, the dial is manipulated to sequentially align the gate slot of each wheel with the fence by incremental movement thereof and while the gate slot of the drive cam is aligned with the fence, applying force between the shackle and casing to measure movement of the shackle relative to the casing at each increment position of at least two of the wheels to determine the combination number of each wheel and/or to open the shackle. A frame is provided with structure for releasably securing the casing member in a first embodiment, and the shackle member in a second embodiment, to the frame wherein the unsecured shackle member or casing member is free to move relative to the frame. Also provided is a movement sensitive device for sensing movement between the shackle and the casing while force is applied between the shackle and casing to determine the combination numbers.

A zipper lock has two locking members to secure two zipper pulls of a suitcase and a control plate to cause the locking member to disengage from the zipper pulls. The lock has a latch engaged with the control plate, the latch positionable in a first latch position when the lock is in a locked mode or in a second latch position to open the lock. The lock has a combination mechanism using dials and clutches to control the movement of a spindle which allows the latch to move the second latch position when the arrangement of the dials matches the correct combination code. The lock also has a key-overriding mechanism using a cylinder to cause the movement of the latch when a correct key is used to turn the cylinder to open the lock. A recovery mechanism allows a user to recover the lost combination code.

A security lock for a door is provided having a bracket on the interior side of the door with a locking bolt mounted in the bracket. The bolt is adapted for movement between a raised, unlocked position above a cavity on the floor below the bracket and a lowered, locked position where the bolt is in the cavity to prevent the door from being opened. A bolt restraint is mounted on the bracket and cooperates with the bracket to maintain the bolt in its unlocked position. The bolt restraint, for example, a spring-loaded ball that engages an annular recess in the bolt, releases the bolt into its locked position when a downward force is applied to the bolt. The locking bolt has an enlarged flange that stops movement of the bolt into the cavity beyond a predetermined location on the bolt.
