Abstract

Techniques for using wireless electronic keys with devices are disclosed. For example, a computer system can program an access code into a programmable wireless electronic key. An action or function of the device can then be made contingent on there being a match between the access code from the key and an access code known by the device. Further still, other operational control parameters (such as time limits) can be programmed into the key to restrict the ability of the key to control an action or function of the device. Also, audit data such as device access history can be wirelessly transferred from a device to an electronic key, whereupon the key can later transfer this audit data to a computer for analysis.
