User Guide
The lock box can be opened using the primary code, a secondary code, or a temporary code, all of which
are found in the app or distributed from the app.
1. Enter the code into the lock box keypad.
2. When the keypad lights green open the lock box by pulling on the door tabs.
Q: The lock box will not re-lock. What should I do?
A: This can occur if the door pins of the lock box are left resting against the lock mechanism without
being closed. This has fooled the lock into thinking it is closed completely.
1. Press any button on the lock keypad and when the lock lights green, close the lock and it will
light blue when locked.
2. If using a code to open the lock box, enter the key code provided, when the lock lights green,
close the lock and it will light blue when locked.
BLUETOOTH COMMUNICATION
Q: What if my phone's Bluetooth is unable to connect to my lock box?
A: Make sure your phone is sufficiently charged. In phone’s settings, make sure that Bluetooth is turned
on. If you can’t turn Bluetooth on, try restarting your phone and then re-launch the app. The lock can be
unlocked by entering the Primary Code, the current Temporary Code or the Backup Master Code on the
lock keypad.
Q: Is a Wi-Fi connection needed to access my lock box?
A: Wi-Fi is not needed for this product. The owner can grant temporary or permanent access to guests
through the Master Lock Vault eLocks app. A guest can then use their Bluetooth enabled device or
manually enter a code into the keypad or to unlock the lock box.
Q: Are these lock boxes susceptible to Bluetooth "hacking"?
A: Master Lock utilizes Bluetooth 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. To provide leading-edge security, we employ
robust, military-grade authentication and encryption mechanisms built upon proven, NIST
recommended and FIPS Approved algorithms to deter sniffing, replay and manipulation attempts that
Bluetooth technology has been associated with. These mechanisms are regularly audited by
independent security professionals.
GUEST ACCESS
Q: How do I share access to my lock box?
A: You can share access to your lock box with friends, family or colleagues. To provide Bluetooth access
via email or text:
1. To enable your guests to access your lock box, open the Master Lock Vault eLocks app.
2. Select the lock to which you would like to provide guest access from the Locks list.
