Abstract: An authentication device includes at least one processor, at least one computer-readable medium, and program instructions stored on the at least one computer-readable medium for execution by the at least one processor. The program instructions include first program instructions to wirelessly pair the authentication device with a controlled access device. The program instructions further include second program instructions to broadcast data indicative of an authorization to grant access to the controlled access device, while the controlled access device is within a predefined range of the authentication device, upon successfully pairing with the controlled access device.

Abstract: A controlled access device includes at least one processor, at least one computer readable medium, and program instructions stored on the at least one computer readable medium for execution by the processor. The program instructions include: first program instructions to continuously listen for advertisement data being broadcast by a lock device, the advertisement data indicative of the lock device being within a predefined range of the controlled access device; second program instructions to automatically retrieve a key for granting access to the controlled access device responsive to the first program instructions detecting the advertisement data while the controlled access device is in a locked state; third program instructions to unlock the controlled access device and grant access to the controlled access device responsive to the second program instructions retrieving the key; and fourth program instructions to lock the controlled access device.
