The Master Lock Bluetooth Indoor Padlock provides secure, keyless access for indoor settings, eliminating the need for traditional keys or forgotten combinations. Designed for durability, it features a 47mm wide metal body and a hardened boron alloy shackle engineered to resist cutting and sawing attempts. Users can manage security and monitor access directly through the Master Lock Vault Enterprise app on compatible Apple and Android smartphones. To ensure reliability, the padlock includes military-grade encryption to protect against digital hacks and unauthorized key duplication. If a smartphone battery is depleted, the device offers a backup entry method via a directional code entered directly on the padlock keypad. The system provides integrated low battery notifications both on the lock hardware and through the mobile application, ensuring users are alerted when power levels are low.
