Masterlock 4401 Outdoor Bluetooth Padlock

The Masterlock 4401 is a Bluetooth-enabled outdoor padlock designed for secure, keyless access control at commercial and industrial sites. Featuring a robust 56mm wide metal body and a high-security boron alloy shackle, this smart padlock delivers maximum resistance to cutting and sawing whilst eliminating the need for physical keys or memorised combinations.

Access is controlled entirely through your smartphone using the Master Lock Vault Enterprise app, available for both Apple and Android devices. The system employs military-grade encryption to protect against physical attacks and digital hacks, ensuring your property remains secure from unauthorised access. With no keys to lose or duplicate, you maintain complete control over who can access your secured areas.

The padlock includes intelligent backup features for continuous operation. A directional code keypad provides emergency access if your phone battery dies, whilst low battery notifications alert you through both the app and the padlock itself. The battery jump feature allows temporary access even when the battery is depleted whilst the lock is engaged. Power is supplied by an easily replaceable CR2 battery, ensuring minimal downtime.

Ideal for contractors managing multiple sites, facilities managers controlling access to equipment stores, or industrial applications requiring audit trails and remote access management.
