Abstract: An aspect of the invention relates to a method for controlling access to a physical resource by a blocking device which can be locked and unlocked, comprising steps of locking and unlocking the blocking device which comprise comparing an access code transmitted by a first individual device with an access code associated with a first agent, and a step of consigning the blocking device using a set of second individual devices, wherein the unlocking can be carried out only when each of the second individual devices of the set has de-consigned the blocking device.

Abstract: A method of using an electronic key for access to one or more mechatronic locks when the key moves from place to place, including the key periodically transmitting its geographical location to an access management server so as to allow said server to identify location coordinates for the key, and receiving an access profile from the server where the access profile includes a set of one or more cylinders accessible to the key and is based at least in part on the key's location. If the key's new location causes a change in access profile information associated with the key, the key's previous access profile is preferably replaced with the key's new access profile in an irreversible manner. The key preferably self-supervises its communications with the server by deactivating its access profile if it no longer receives information from the server for a predetermined period of time.

Abstract: The invention relates to electronic keys. The invention relates more particularly to an electronic key for secure access to an electronic cylinder. The invention relates to an electronic key (1) enabling control of access to a mecatronic cylinder, wherein said key comprises at least one memory (3) for storing access information, and a microprocessor. The invention is characterized in that said key comprises at least one means of wireless communication with a server (7), comprising an access profile data base, wherein said access information can be remotely modified according to the access profile associated with said key.
