A cylinder lock and an associated key, the lock comprising 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 comprises a substantially longitudinal compartment for the functional accommodation of a key which comprises a grip portion from which an elongated body extends which is provided with coding grooves and protrusions on its outer surface; between the plug and the body there are respective accommodation channels for translating coding elements, which open onto the substantially longitudinal compartment; the plug comprises 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 is constituted by at least one pin and at least one conical portion.

An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electro-mechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state. The interchangeable electro-mechanical lock core may include a core keeper moveably coupled to a lock core body. The core keeper may be positionable in a retain position wherein the core keeper extends beyond an envelope of lock core body to hold the lock core body in an opening of the lock device and a remove position wherein the core keeper is retracted relative to retain position to permit removal.

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.

Cylindrical locks and more specifically a set of profile members in combination with a rotatable cylindrical key plug have a longitudinal keyway with a profile corresponding to an associated key. Each profile member is accommodated in an associated cavity in the key plug at a lateral side of the keyway so as to form a lateral part thereof. The profile members have a non-circular cross-section and are non-rotatably mounted in the associated cavities at a location adjacent to the keyway. A portion of each profile member has a profiled surface portion facing inwards toward the opposite lateral side of the keyway, the profiled surface portion having, in a plane being transversal to a longitudinal axis of the key plug, a specific profile section defining a local, lateral part of the keyway. An associated key, and a method to manufacture a cylindrical key plug with such profile members are also disclosed.

A locking mechanism is provided for a lock body and a rotatable key plug. The locking mechanism comprises pins having recesses, each of the pins adapted to be disposed in pin bores in the key plug for reciprocal and rotational movement. An elongated spring member simultaneously engages and biases the pins toward a keyway in the key plug. A locking bar moves between a first position and a second position where at least a portion of the locking bar is received in the recesses in the pins. The locking bar is prevented from moving to the second position unless the pins are in a position where the recesses are aligned with the locking bar. Upon insertion of a key in the keyway the pins are moved axially or rotated for aligning the recesses in the pins with the locking bar so the key can rotate the key plug.

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 lock cylinder including a plug, a plurality of key followers, a sensor assembly structured to sense positions of the key followers, and a controller in communication with the sensor assembly. The plug includes a keyway and a plurality of plug tumbler shafts. Each of the key followers is movably seated in a corresponding one of the plug tumbler shafts and includes a sensor interface. The sensor assembly includes a plurality of sensors, each of which includes at least one sensing region. Each of the key followers is associated with one of the sensors via an associative link formed between the sensor interface and the corresponding sensing region. The sensors are structured to generate an output signal indicative of the transverse position of the associated key follower, and the controller is structured to select and perform actions based upon the output signals.

An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electro-mechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state. The interchangeable electro-mechanical lock core may include a core keeper moveably coupled to a lock core body. The core keeper may be positionable in a retain position wherein the core keeper extends beyond an envelope of lock core body to hold the lock core body in an opening of the lock device and a remove position wherein the core keeper is retracted relative to retain position to permit removal.

A cylinder lock includes a housing; a cylinder rotatably provided therein and having first and second ends, the cylinder extending in a longitudinal direction between the first and second ends and including an internal keyway for placing a key corresponding to the lock in the cylinder; a locking mechanism that prevents rotation of the cylinder with respect to the housing when the key is not present in the keyway; a blocking element positioned between the first and second end, and configurable to take a first position wherein the keyway is blocked such that the key cannot be placed in the keyway and a second position wherein the keyway is unblocked such that the key can be placed therein; a configuration device to configure the blocking element in the first or second position, and controllable by wireless communication between the lock and a remote control unit.

The invention relates to a flat key (1) for a cylinder lock (11), said flat key comprising: a key bow (2) and a key shaft (3) that extends substantially parallel to a key longitudinal axis (L) and has a key tip (4), wherein at least one surface coding (6) designed to be read in the cylinder lock (11) is located at the end face (5) of the key tip (4); and a cylinder lock (11) for receiving such a flat key (1), and a locking system comprising one or more such flat keys (1) in combination with one or more such cylinder locks (11).
