DYNAMIC ELECTRONIC DOOR LOCK CONTROL SYSTEM
First Claim
1. A method of controlling access to a building, comprising:
- installing an electronically-controlled lockset on an exterior door of a building, wherein a locking mechanism of the electronically-controlled lockset is disposed in an operable relationship with a door frame in which the exterior door is installed and the state of the locking mechanism controls whether the exterior door may be opened, wherein the electronically-controlled lockset is configured to release the locking mechanism upon an access code being entered into the electronically-controlled lockset, wherein the access code is valid for releasing the locking mechanism for a predetermined window of time;
maintaining a reference device at a separate location that is located remotely from the building, the reference device being configured to generate a current value of the access code, wherein the current value of the access code is time-synchronized with the electronically-controlled lockset; and
providing the current value of the access code to a user in response to a request from the user for the access code to access the building.

Abstract
A method of controlling access to a real estate property includes installing a dynamic electronically-controlled lockset on an exterior door of a real estate property, maintaining, at a remote location, a reference device adapted to present a value of a second dynamic access code to one or more users located in the real estate office, receiving, at the real estate agent location, a request from a user for a current value of the second dynamic access code, examining the reference device to determine the current value of the second dynamic access code, and providing the current value of the second dynamic access code to the user for input into the electronically-controlled lockset. The lockset is adapted to unlock upon receiving a value corresponding to a first dynamic access code programmed therein. The second dynamic access code is time-synchronized with the first dynamic access code programmed in the electronically-controlled lockset.

6. A system for controlling access to a building, comprising:
-
a computing device; an application executable on the computing device, wherein the application comprises; logic that generates an access token for the building in response to receiving a request for the access token from a client device; and logic that transmits the access token to the client device. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. An apparatus for controlling access to a building, comprising:
-
an input mechanism configured to receive an access token; an electronically-controlled locking mechanism communicatively coupled to the input mechanism, wherein the electronically-controlled locking mechanism is configured to enter an unlocked state in response to the input mechanism receiving a valid access token; and token validation circuitry communicatively coupled to the input mechanism and the electronically-controlled locking mechanism, wherein the token validation circuitry is configured to periodically generate a reference access token and the token validation circuitry is configured to compare the access token received via the input mechanism to the reference access token to determine whether the access token is valid. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
