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 electromechanical lock assembly (1) comprising a lock body (13), a lock core (21) located at least partially within the lock body (13) and selectively rotatable with respect to the lock body (13), the lock core (21) including a key receptacle (23), a bolt operating member rotationally secured to the lock core (21) and configured to move a lock bolt of a lock (3) for locking and unlocking said lock (3), and a programmable key (12), wherein said electromechanical lock assembly is configured to be powered upon insertion of the programmable key (12) in said key receptacle (23). A position sensing device (27) is arranged to transmit position data to said programmable key (12).

The present invention relates to an electromechanical lock assembly (1) comprising a lock body (15), a lock core (17), a lock bolt operating member (19), and an electronic access control device. The electromechanical lock assembly further comprises an annular element (27) which is rotatably and axially displaceably mounted on said lock core (17), a coupling device (25) arranged to communicate with said electronic access control device and, upon the insertion of an appropriate key (65) in a key receptacle (37) of the lock core (17), rotationally lock the annular element (27) to the lock core (17), thereby enabling rotation of the lock core (17) in a first direction and thereby enabling unlocking of a lock (3) with said appropriate key (65), and a blocking arrangement (63) arranged to prevent unauthorized unlocking of said lock (3).

An electronic key may include a partial capacitor comprising a capacitive metal plate in communication with a processor. The capacitive metal plate of the partial capacitor is configured to form a capacitor with a corresponding capacitive metal plate of a lock when brought into proximity with the metal plate of the lock. Data may be transferred from the key to the lock using a capacitor formed by combining the two metal plates, wherein a common ground is established between the metal plate of the key and the metal plate of the lock through a parasitic capacitance present between the key and lock circuitry. Audit trail data may be recorded based on usage of the key.

The present disclosure relates a set of electronic keys for an electronic lock. The set of electronic keys includes at least one passive electronic key having a passive digital key, and at least one active electronic key having an active digital key. Each of passive and active electronic keys includes a communication channel and an electronic key power supply port. The active electronic key includes electrical power source providing electrical power supply to the active electronic key itself, the electronic lock and the passive electronic key through the electronic lock to operate the electronic lock. When both active and passive electronic keys are inserted into respective electronic keyholes of the electronic lock, both active and passive digital keys are transmitted to the electronic lock, the electronic lock can be locked and unlocked only when both active and passive digital keys received match prestored active and passive digital keys respectively.

A method for operating a locking system comprising an electronic key and an electronic lock and a central unit which in locking operation is used locally separately from the electronic key and the electronic lock, wherein in the method an external authorization code is generated by the central unit by means of an authorization code determination program, the external authorization code is transferred to the electronic key and the external authorization code is saved in a memory by the electronic key, wherein, on interaction of the electronic key with the electronic lock, the external authorization code is read out from the memory by the electronic lock and is checked by a processor of the electronic lock in that, using an internal authorization code determination program, the processor itself determines an internal authorization code and compares it with the external authorization code received by the electronic key and wherein, in the event of the determined internal authorization code being identical to the transferred external authorization code, the processor permits an opening process.

The invention relates to an electronic key (32) having at least two contacts (324, 325, 326) for the transmission of data and/or energy to an electronic lock (16). In accordance with the invention, the housing (321) of the electronic key (32) comprises an input device (33) for the entry of an authorization code (36). The invention also relates to an electronic closure system with an electronic key (32) and an electronic lock (16) as well as to a method for secure acquisition of an access authorization or for secure delivery of a key to at least one user (22) by means of an electronic lock (16) and at least one electronic key (32) carried by the user (22).
