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.
