One-time access for electronic locking devices

A system, comprising:

• a server;
• a handheld device associated with a non-keyholder, wherein the handheld device is configured to communicate access information to the server over a long-range wireless communication link, wherein the access information comprises data from which an electronic locking device identifier can be inferred and an identifier from which an identity of the non-keyholder associated with the handheld device can be determined;
• and
• an electronic locking device configured to communicate with the handheld device over a short-range wireless communication link, wherein the electronic locking device is further configured to receive over the short-range wireless communication link an access code received from the handheld device over the short-range wireless link,
• wherein the server is configured to transmit a set of instructions and an access application over at least the long-range wireless link to the handheld device, wherein the set of instructions is configured to cause the handheld device to install the access application and execute the access application, wherein executing the access application causes the handheld device to send the access code to the electronic locking device to unlock the electronic locking device;
• wherein the set of instructions and the access application are transmitted over the long-range wireless link to the electronic locking device and over the short-range wireless link from the electronic locking device to the handheld device.
