A key handle assembly for improving key usability for persons having limited dexterity includes a body. The body has a first side, a second side, and a perimeter edge extending between the first and second sides. The perimeter edge has a top edge, a bottom edge, a front edge and a rear edge. The front edge of the body has a plurality of notches extending therein and toward the rear side, and through the top and bottom edges. Each of the notches receives a key pivotably through the body. A plurality of intermediate walls is defined on opposite sides of the notches. The body has an aperture extending into the first side and through each of the intermediate walls. A rod extends through the aperture, through each of the intermediate walls and through a key hole in the key such that the key is pivotably coupled to the body.

A key for use in a cylinder lock with a rotatable key plug having an elongated key blade with a relatively wide lower portion and a relatively narrow upper portion. A step-like transition region between the wider lower portion and the narrow upper portion. The key blade includes a longitudinal profile groove located adjacent to the step-like transition region that extends along at least a portion of the length of the blade. An inner wall of groove is substantially parallel to a side surface of the lower portion of the key blade. The longitudinal profile groove includes an undercut portion adjacent to and inside a ridge portion of the key blade. The outside of ridge portion forms a part of the side surface of the blade in the relatively wide lower portion up to the step-like transition region and the inside of ridge portion facing inner wall of the groove.

A disclosed device may have a clamping mechanism operably coupled to a rotatable positioning mechanism, the clamping mechanism being intended to retain a position of at least one key. The device is shaped such that additional torque can be applied to the key when rotating the key when inserted in a lock. In some embodiments, a light source may be included with the device.

Safety device (1) for holding and sharing among a plurality of users a key (100) provided with a remote control (102). The safety device (1) includes: an external housing (2) adapted to internally contain said key (100), configurable according to an open configuration and a closed configuration; a lock (5) that can be commanded for switching between a closed status, that prevents said external housing (2) in the closed configuration from switching into the open configuration, and an open status, that enables the external housing (2) to switch between the open and the closed configurations; means for interacting with said remote control (102) of the key (100); a transmission unit (18) configured to receive, directly or via an external server (107), command signals from an external command device (19); and a command and control unit (17).

A vehicle card key, includes: a mainboard part on which an electronic element for wireless transmitting/receiving with a vehicle is mounted; a connector part formed on the mainboard part; a housing part which covers the mainboard part avoiding the connector part; and a switchboard part which has at least one among a switch and light-emitting diode mounted thereon, and which is layered on the mainboard part and is connected to the connector part.

A linearly-actuated lock including a housing, a lock case received within the housing along an axis, and a lock barrel rotatable relative to the lock case between a locked state and an unlocked state. The lock barrel includes tumblers and tumbler springs. The lock further includes a key insertable into the lock barrel to displace the tumblers relative to the lock barrel in a direction parallel to the axis and a sidebar extending through apertures of the lock barrel. The sidebar is engageable with a notch of the tumblers when the sidebar moves radially inward relative to the axis. The sidebar includes a cam surface slidable against at least one of the housing and the lock case when the lock barrel rotates. The sidebar also includes a projection having a single-ramped surface received within the notch of each tumbler when the lock barrel is in the unlocked state.

The present invention, in a non-limiting example embodiment provides a locking apparatus and method for securing locking hardware without the use of a key. In an example embodiment, the apparatus comprises at least a keyless insertion rotatable disk-style, barrel locking apparatus that, in a locked state can be inserted into a securing device without first unlocking, and then, thereafter, locking after insertion. In a nonlimiting example embodiment, unlocking and re-locking requires a key. The present invention, in an example embodiment, also provides features that allow the locking apparatus to enter and exit multiple apertures without requiring a key.
