Meet a flexible security companion designed for spaces with multiple users. The Master Lock Black Outdoor Bluetooth Smart Padlock with Keypad combines convenient smartphone access with a durable keypad option, so you can grant entry without passing keys. Bluetooth unlock works with the Master Lock Vault apps, and no Wi-Fi is required for everyday use. The lock is built for outdoor settings, making it suitable for gates, sheds, job sites, Airbnbs, and other shared locations where reliable access control matters.

Flexible access for real-life scenarios

Unlock with a compatible smartphone via Bluetooth or enter a secure keypad code when needed. You can temporarily disable Bluetooth when storing your phone with the lock to reduce chances of unauthorized use, and you can grant temporary or permanent access to others through the apps or keypad. This setup is helpful for property managers, maintenance teams, rental hosts, and family members who require controlled entry without fuss.

Smart monitoring that keeps you informed

The lock works with the free Master Lock Vault Home and Vault Enterprise apps on Android and iOS to provide tamper alerts and low-battery notices. Real-time insights help you track access and stay on top of device health, especially across multiple users or locations.

Rugged, weather-ready design

With a metal body and a boron-steel shackle, the padlock aims to resist physical attacks while a two-piece weather cover shields the mechanism from rain, dust, and harsh outdoor conditions. Its compact form makes it suitable for gates, fences, sheds, job sites, and indoor lockers, all while offering reliable security you can trust day in and day out.
