Abstract: The invention concerns a system (1) to provide access to premises (P1-P4) that comprise entrances (E1.1, E1.2, E2-E4) locked by means of electromechanical key locks (L1.1, L1.2, L2-L4), which for locking and unlocking are powered by insertion and actuation of at least one programmable key (24). In said system (1) an administrator (10) contacts a service unit (20) in possession of a programmable key (24) and provides it with synchronization data (13) for an electromechanical key lock (L1.2) of at least one entrance (E1.1) of at least one premise (P1) at an exact geographic position of a site (S).

Abstract: 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).

Abstract: 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).
