A lock core includes a shell, a plug within and rotatable relative to the shell between a first position and a second position about a longitudinal axis of the plug, and a lock. The lock has a first locked position preventing rotation of the plug relative to the shell, an unlocked position allowing rotation of the plug relative to the shell and a second locked position different from the first locked position preventing rotation of the plug relative to the shell. The lock is moveable from the first locked position preventing rotation of the plug relative to the shell to the unlocked position with a first movement of the lock, the first movement having a vector component along the longitudinal axis of the plug and a vector component along an axis transverse to the longitudinal axis of the plug

A cylinder lock and an associated key, the lock including a fixed body and a plug which is accommodated within a respective cavity of the body and can rotate with respect to the body. The plug includes a substantially longitudinal compartment for the functional accommodation of a key which includes a grip portion from which an elongated body extends and which is provided with coding grooves and protrusions on its outer surface. Between the plug and the body are respective accommodation channels for translating coding elements, which open onto the substantially longitudinal compartment. The plug includes at least one auxiliary duct which faces the substantially longitudinal compartment and extends at least partially in the body for the sliding accommodation of at least one coding unit that includes at least one pin and at least one conical portion.

The invention relates to a key (1) for locking a cylinder lock, comprising at least one first surface (2) and at least one second surface (2), with sensing positions (4) provided along the longitudinal extent of the key (1), wherein at least one code (3) is provided on the first surface (2) and wherein at least one further code (3) is provided on the second surface (2), the codes comprising control points (6, 6, 7, 7) at the sensing positions (4) that are provided transversely to the longitudinal extent of the key (1) and arranged at certain control heights (5), wherein at least at one sensing position (4) at least one control point (25, 25) has a different dimension, preferably a larger diameter, on the two surfaces than a control point (6, 6, 7, 7) at another sensing position (4). The invention also relates to a lock for such a key and a system made up of at least two locks and at least one key.

The disclosure relates to an improved cylinder lock, key and their combination. More specifically, the disclosure relates to a locking pin assembly operable to provide added combination and increase security against burglary, such as by key bumping, a cylinder lock incorporating the locking pin assembly and key blade and key blade assemblies having the configuration to actuate the locking pin assembly.

A key or key blank includes a key blade having a first edge, a second edge, and first and second opposed sides. The first edge has one or more edge bittings to elevate and/or rotate one or more tumbler pins of a lock with a vertically-oriented keyway, and one of the opposed sides has one or more side bittings to elevate and/or rotate one or more tumbler pins of a lock with a horizontally-oriented keyway. Side warding surfaces on the key blank are shaped and positioned to minimize the interference of peaks between the skewed bitting cuts on the key. A lock has a keyway configured for the key having edge bittings to elevate and/or rotate one or more tumbler pins of a vertical lock and side bittings to elevate and/or rotate one or more tumbler pins of a horizontal lock.

A lock core includes a shell, a plug within and rotatable relative to the shell between a first position and a second position about a longitudinal axis of the plug, and a lock. The lock has a first locked position preventing rotation of the plug relative to the shell, an unlocked position allowing rotation of the plug relative to the shell and a second locked position different from the first locked position preventing rotation of the plug relative to the shell. The lock is moveable from the first locked position preventing rotation of the plug relative to the shell to the unlocked position with a first movement of the lock, the first movement having a vector component along the longitudinal axis of the plug and a vector component along an axis transverse to the longitudinal axis of the plug.
