Key Design Elements

• Compact Shackle Length: The shackle measures 50 mm, making it suitable for a wide range of interior lockable spaces while maintaining a slim profile.
• Durable Body Construction: Crafted from high‑strength alloy, the padlock’s body resists impact and tampering. Its matte gray finish provides a neutral aesthetic that blends seamlessly with most indoor environments.
• Integrated Bluetooth Module: The internal module is sealed to protect against moisture and dust, ensuring reliable operation in typical indoor conditions.
• Secure Keypad Interface (Optional): For users who prefer a physical backup, the lock can be paired with an optional keypad that accepts numeric codes.

Connectivity & Control Features

The padlock’s core advantage lies in its wireless connectivity. By pairing it with the Master Lock Smart Access app, users gain:

• Remote Unlocking: Open or close the lock from anywhere within Bluetooth range (typically up to 10 m).
• Access Logs: View a chronological record of all unlock events, including time stamps and device identifiers.
• Multiple User Profiles: Create distinct profiles for family members or staff, each with customizable access schedules.
• Temporary Access Codes: Generate one‑time codes that expire after a set duration, ideal for guests or temporary users.

Security Protocols

The padlock employs industry‑standard encryption to safeguard communication between the lock and mobile device. Key features include:

• AES‑128 Encryption: All data transmitted over Bluetooth is encrypted, preventing eavesdropping.
• Secure Pairing Process: The initial pairing requires a unique QR code or manual key entry to establish trust between devices.
• Tamper Detection: If the lock detects forced opening attempts, it triggers an alarm within the app and can be set to auto‑lock after a short delay.

The padlock is powered by a rechargeable lithium‑ion battery. Key points include:

• Long‑Lasting Operation: Under normal usage, the battery can sustain up to 12 months of operation before requiring recharge.
