A multi-key lock core includes a housing, a driving cylinder, a plurality of circular lock plates, and a lock rod. The driving cylinder is disposed in the housing, a sidewall of the driving cylinder is provided with a penetration portion, and the driving cylinder is rotatable to the penetration portion to correspond to an engagement recessed portion. The circular lock plates are disposed in the driving cylinder and each include an outer edge provided with a first recessed portion, and the outer edge of at least one of the circular lock plates is further provided with a second recessed portion. The lock rod is disposed in the penetration portion, and may partially enter the engagement recessed portion to restrict rotation of the driving cylinder. A first key may push the circular lock plates to rotate to the first recessed portion to correspond to the penetration portion, so that the lock rod can move to partially enter the first recessed portion and detach from the engagement recessed portion. The second key may push the circular lock plates to rotate to the second recessed portion and the first recessed portion to correspond to the penetration portion, so that the lock rod can move to partially enter the second recessed portion and the first recessed portion and detach from the engagement recessed portion.

The lock(100) comprises a controller, a data storage device, a lock mechanism operable by the controller in a locked state or an unlocked state, and a data communication frontend comprises a first data port(108) and a second data port; Wherein the controller is configured to enter into data communication via second data port after successful completion of data communication via the first data port(108). An electronic key(200) comprises a key controller, a data storage device, a power source and a data communication frontend comprising a first data port(202) and a second data port; wherein the electronic key(200) is a physical key having a key body and is configured to work with the lock(100).

An exemplary lock apparatus includes a housing and a plug assembly rotatably mounted in the housing. The plug assembly includes a tumbler assembly operable to selectively prevent rotation of the plug assembly relative to the housing and a retention mechanism operable to selectively prevent removal of the plug assembly from the housing. A system including the lock apparatus may include a change key configured to actuate the tumbler assembly without actuating the retention mechanism and/or a control key configured to actuate both the tumbler assembly and the retention mechanism.

The invention relates to a swivel lever device for actuating a closure apparatus, in particular a bolt-closure means and/or bar-closure means, of an access control device, in particular a door and/or hatch, having: a housing for fastening the swivel lever device, in particular to the access control device, and a swivel lever for actuating the closure apparatus, the swivel lever be movable relative to the housing between an arresting position and an actuation position for actuating the closure apparatus, the swivel lever in the actuation position being pivotable about an actuation axis relative to the housing, a locking mechanism for securing the swivel lever against unauthorised movement from the arresting position into the actuation position being provided, and the locking mechanism comprising at least one locking element, which can be moved between a locked position for interlockingly blocking the movement of the swivel lever from the arresting position to the actuation position and an unlocked position for releasing the movement of the swivel lever from the arresting position into the actuation position. To achieve better protection against damage and contamination, according to the invention the locking element includes at least one locking magnet for moving the locking element from the locked position into the unlocked position by means of the magnetic interaction between the locking magnet and at least one unlocking magnet of a corresponding key unit.

An electric lock device for furniture or storage has an RFID transmitter/receiver for communication with portable data carriers. A controller detects a data carrier nearby, reads a set of data from it, and determines if the data carrier is at least an access requesting or function determining type. If access requesting, the controller retrieves identity information from the read set of data, compares the identity information to stored reference information, and controls an electric activator for a securing member. If function determining, the controller retrieves function determining information from the read set of data and performs any of the following: switching to any of a plurality of operational modes having different principles for access control; reading an operational status; or setting an operational parameter. At least one of these actions is variable controlled and based on a variable value in the function determining information.

A dual key lock core and a key lock core assembly using the same are provided. The dual key lock core of the present invention includes a lock core rod, a driving rod, and an outer barrel. The lock core rod includes a wedging part and an inner barrel disposed at opposite ends. The inner barrel has a hollow guiding groove, an inner barrel protrusion, and a first lock structure. The driving rod is rotatably capped within the inner barrel. One end of the outer surface of the driving rod has a driving protrusion. The other end of the outer surface of the driving rod has a second lock structure. The driving protrusion is in and movable along the hollow guiding groove when the driving rod is capped within the inner barrel.

A double cylinder lock is disclosed which includes a first of the cylinders, called a service cylinder, being actuatable by a first key, the second of the cylinders, called a customer cylinder, being actuatable by a second key distinct from the first key, wherein the service cylinder may only be actuated once at most between two actuations of the customer cylinder the lock also including a module for detecting the actuation of the service cylinder.
