This can occur if the lock shackle is closed and opened again quickly before the motor has time to relock the lock. Press any button on the lock keypad and when the lock lights green, close the lock and it will light blue when locked.

If moisture on the lock keypad freezes so that a button cannot be pressed, we recommend warming the lock keypad between gloved hands for a short time to melt the ice until the button can be pressed. The lock should then resume normal operation.

If the lock is in Touch Unlock mode, push the top of the metal shackle firmly down into the lock body to ensure proper mechanical engagement. Then, press any button on the lock and it should light blue and unlock, resuming normal operation. If the lock is in Swipe Unlock mode, push the top of the metal shackle firmly down into the lock body to ensure proper mechanical engagement. The app should change to blue to show as locked and then display the swipe arrow prompts to unlock the lock, resuming normal operation. If you are trying to unlock using a directional manual code on the lock keypad, push the top of the metal shackle firmly down into the lock body to ensure proper mechanical engagement. Then, enter the manual code on the lock keypad. It should light blue and unlock, resuming normal operation.

To locate the lock's Activation Code on the instruction sheet included in the lock packaging:
 
1) On the front of the package, cut through the two plastic ribs behind the lock's shackle and remove the lock from the package.
2) Remove the folded instruction sheet from behind the shackle.

The Master Lock Home app and Vault Home web interface function best for users with 10 locks or less. The Master Lock Vault Enterprise program has been designed for businesses and organizations that use more than 10 locks and Master Lock suggested upgrading to the Enterprise system to maximize the experience when using higher numbers of locks.

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. 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.
