The Masterlock 4400 is a Bluetooth-enabled indoor padlock that combines modern smart technology with robust physical security, ideal for tradespeople and contractors seeking keyless access control for indoor applications. This digital padlock features a 47mm wide metal body and a boron alloy shackle with 7mm diameter, delivering maximum resistance to cutting and sawing attacks. The smart lock operates via the Master Lock Vault Enterprise app, compatible with both Apple and Android devices, eliminating the need for keys or combinations while preventing unauthorised duplication.
Security is enhanced through military-grade encryption alongside high-security physical features, protecting your tools and equipment from both physical attacks and digital hacks. The padlock includes a directional backup code system accessed via the lock's keypad, ensuring you can still gain entry if your phone battery runs flat. Low battery notifications appear both on the padlock itself and within the app, preventing unexpected lockouts.
This Bluetooth padlock is particularly suitable for securing tool storage, contractors' site boxes, and indoor equipment lockers where multiple authorised users require managed access without key distribution. The smart technology allows site managers and business owners to grant and revoke access remotely through the app, maintaining complete control over who can open the lock.
