Abstract: Currently, people at a public or private location wishing to store their valuables have limited options. They may use a token locker where a coin-shaped token is inserted into and retained by the locking device, allowing the release of a locking key. They may use a similar electronic version of the token locker. In some cases, they may have to bring their own lock or even a separate private locker to store their valuables. The standard token requires a new token to be inserted each time the door is opened and leaves the location unable to track the duration of use. Electronic devices can be expensive and require a source of electricity. Bringing a lock or entire lock box is cumbersome. The solution is a process whereby a universal key is used in place of a token. This universal key, as a token would do, releases a unique locking key from the locker. The universal key, labeled for tracking, is borrowed for use at the location.
