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.

The activation code is included in the Instruction Sheet included in the box with the lock.

If the battery dies while the lock box is closed, it can be unlocked using an external battery.

1. If battery dies in locked position, locate battery jump contacts on the bottom of the lock box.
2. Hold a new 9-volt battery underneath the lock box with the positive (+) and negative (-) terminals pressed against the jump contacts.
3. While holding the battery in place, with an authorized mobile device within range of the lock box, press any keypad button on the lock box. If lock does not unlock, enter Primary Access Code on the lock box keypad.
4. When lock box is opened, install a new battery.

Please note that after installing a new battery, the low battery icon will no longer display in the App after the lock box and App communicate with each other. However, it will take between 2 and 72 hours for the yellow LED to stop displaying on the lock itself.

To prevent battery theft or tampering, the battery drawer on the 4400 series and the battery door on the 4401 series can only be opened with the lock in the unlocked position. The drawer on the 4400 series can only be extended part way with the lock in the locked position, to allow for an external battery to access the jump contact.

After installing a new battery, the low battery icon will no longer display in the app, after the app and the lock communicate with each other. However, it will take 2 to 24 hours on the Indoor Padlock (4400), and 2 to 72 hours on the Outdoor Padlock (4401), for the yellow LED to stop displaying on the lock itself.

To change the battery:
1. Open the lock box door.
2. With a flat head screwdriver, open the battery compartment located behind the door of the lock box.

If using Bluetooth credentials, 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 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.

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.
