Managing access to physical assets

摘要

A decentralized key management system for controlling access to multiple vehicles among multiple users includes vehicle keys for the respective vehicles, individual locking key containers for the vehicles, electronic access devices for assignment to the users and a database. Each of the containers has a storage area within which a vehicle key or keys for one vehicle can be stored operable to unlock key containers if authorized. The access devices are operable to unlock the key containers if authorized. The access devices are programmable with information from the database such that an assigned access device is programmed with a specific user's access privileges for obtaining access to one or more of the vehicles in the system.
