Master Lock Bluetooth Lock Boxes have been designed for ease of use and security. When opening with Bluetooth credentials through the Master Lock Vault APP, no pin code or key card is needed. Primary and secondary codes are only used as an alternative form of entry.

These mechanisms are regularly audited by independent security professionals.
