Abstract
Embodiments relate to enhanced auditing features for administration of remote electronic keys. Based on access control information associated with the electronic key, an unlocking signal is conveyed from the electronic key that causes an electronic lock to change from a locked state to an unlocked state, thereby permitting a user of the key to access one or more resources secured by the lock. The electronic key stores details related to the unlocking event in memory sites. In some aspects, the electronic key broadcasts a message via a wireless wide area network (WWAN). The message may include a request to establish a WWAN communications link with an access control server located away from the electronic key. Responsive to establishing the WWAN communications link, the electronic key initiates a transfer of data to the access control server, the data including details related to the unlocking event.
