Master Lock 5441ENT Bluetooth Key Lock Box
The Master Lock 5441ENT Bluetooth key lock box provides secure, wall-mounted storage for building keys and access cards. Designed for business and institutional use, it works with Master Lock Vault Enterprise to help organisations manage access across multiple users, properties and secure locations.
The lock box is suitable for facilities managers, property managers, maintenance teams, contractors, schools, commercial premises and other organisations that need to provide controlled access without arranging a physical key handover.
Vault Enterprise Access Management
Vault Enterprise is designed for businesses managing many locks and many users. Administrators can manage individual lock boxes or a wider access system using the Enterprise app and web interface.
Access can be granted to individual users or groups and can be temporary, scheduled or ongoing. Permissions can also be changed when contractors finish work, employees leave or access requirements change.
Smartphone and Keypad Access
Authorised users can open the 5441ENT using a compatible smartphone and their assigned Vault Enterprise credentials. A built-in numeric keypad provides an alternative access method where an approved code has been issued.
This combination helps sites provide managed access without relying on shared physical keys or permanently displayed combinations.
Access History and Accountability
Vault Enterprise provides detailed access history and reporting tools. Administrators can review who accessed each compatible lock box and when the access occurred, supporting improved accountability across managed buildings and distributed sites.
Large Key and Access-Card Compartment
The internal compartment is designed to hold traditional keys and access cards. This makes the lock box suitable for building keys, plant-room keys, service-area keys and other credentials that authorised personnel may need to collect on arrival.
Check the size of unusually large vehicle keys, attached fobs or bulky key bundles before ordering.
Weather-Resistant Metal Construction
The 5441ENT has a durable metal body with a coated, weather-resistant finish. It is designed for permanent wall-mounted installation and is supplied with mounting hardware.
Install the unit on a sound surface using fixings suitable for the wall construction. A sheltered location is advisable where practical to reduce unnecessary exposure to severe weather.
Replaceable Battery and Low-Power Warning
The lock box uses one replaceable CR123A battery, which is supplied with the product. A low-battery warning helps users arrange replacement before the battery becomes exhausted.

- Facilities and property management
