Claim Text:
1. A method for allowing a user to securely access a structure using a wireless user device comprising the steps of: storing access permissions identifying at least one wireless user device authorized to access the structure in an electronic database; connecting to the wireless user device using an access node positioned adjacent to the structure and having a short-range wireless radio for connecting to the wireless user device; receiving at the access node identification information uniquely identifying the wireless user device from the wireless user device; programmatically determining using at least one processor that the wireless user device is authorized to access the structure based on the access permissions and the identifying information; repeatedly transmitting a secure unlock key from the access node to the wireless user device and a secure authorization key corresponding to the secure unlock key from the access node to the mechanical locking device securing a door of the structure, wherein the secure unlock key and the secure authorization key are valid for only a predetermined time period following their transmission; receiving at the mechanical locking device an unlock request from the wireless user device, wherein the unlock request is based upon the most recent secure unlock key transmitted to the wireless user device by the access node; programmatically determining using the at least one processor that the received unlock request corresponds to the most recent secure authorization key received by the mechanical locking device from the access node; and unlocking the mechanical locking device to provide the user with access to the structure.
