DEVICE AND SYSTEM FOR CONTROLLING SECURE KEY ACCESS USING AN INTERNET-CONNECTED KEY BOX DEVICE

A system for controlling key access using a phone and internet-connected key box device. The key box device hangs or mounts on a fixture and controls key access to visitors. Visitors may unlock a chamber in a key device for key access by calling the phone number on the key box device display and passing an authentication process during a scheduled time. The key box device owner may monitor and remotely control access to the key box and its key chamber via a software application on cloud computing services that interfaces with operations programmed into a circuit board in the key box device.
