Abstract
A request for an access code for a locking mechanism is received; and a non-permanent use access code for the locking mechanism is subsequently issued. The non-permanent use access code may be issued from a list of currently available access codes for the locking mechanism in response to a request therefor, for example by a merchant or delivery service. Such a code may be issued by a server, which server is further responsible for updating the list of available access codes in response to an indication that a code has been used or has otherwise expired. Such a code may also be issued by a locking mechanism controller The list of currently available access codes is preferably a subset of all access codes for the locking mechanism, which codes may be generated using a cryptographically strong random number generator.
