A: Master Lock utilizes Bluetooth Smart technology to facilitate wireless communication between locks and mobile devices. These locks and lock boxes are designed in a way that prevents the threat of Bluetooth hacking that exists with some other Bluetooth products.

These mechanisms are regularly audited by independent security professionals.
