Master Lock 6440ENT Bluetooth Door Controller for Commercial Access

Master Lock 6440ENT Bluetooth Door Controller for Commercial Access

The Master Lock 6440ENT is a dedicated Bluetooth door controller for commercial use, designed to bring smartphone-managed access control to doors fitted with electric strikes or magnetic locks. It is part of the Master Lock Vault Enterprise system, so a single administrator can grant, change or revoke access across many doors and users from one app - without cutting or collecting a single physical key.

The controller integrates with your existing electric strike or magnetic lock hardware, mounting within the door frame or a secure enclosure. Authorised users open the door with their phone over Bluetooth, and every access event is recorded for a full audit trail. It suits facility managers, strata and body-corporate common doors, logistics and storage sites, and any commercial entrance where keyless, accountable access is the goal.

Master Lock Vault Enterprise

The 6440ENT is managed through the Master Lock Vault Enterprise app, available on iOS and Android as well as a web interface. Vault Enterprise is Master Lock's business-grade platform for managing many locks and many users - assigning access to individuals or groups on a temporary or ongoing basis, reviewing access history, and exporting audit data. The 6440ENT sits alongside the Master Lock Vault Enterprise padlocks and Bluetooth key safes as the door-mounted member of the same access-management system.

For a commercial buyer weighing up how a Bluetooth access platform fits an office, retail or facilities environment, see our guide to choosing a smart lock platform for commercial use, and our overview of the Master Lock enterprise access range.

Master Lock Vault Enterprise Range

The 6440ENT is the door-controller member of the Master Lock Vault Enterprise Bluetooth range. The same platform also covers enterprise padlocks and Bluetooth key safes, so access to gates, plant, cabinets, key storage and doors can all be managed from one app.

Also worth knowing: the Master Lock Vault Enterprise Bluetooth key safes use the same app, so keys and access cards can be stored and shared under the same audit trail as your controlled doors.

Full Specifications

Power and wiring requirements depend on the electric strike or magnetic lock the controller is paired with. Confirm the electrical specification for your specific door hardware with your installer before ordering.

Frequently Asked Questions

Does the 6440ENT need Wi-Fi or a gateway?
No. It communicates with authorised phones over Bluetooth through the Master Lock Vault Enterprise app - there is no separate Wi-Fi bridge or gateway. Access permissions and audit data sync when a phone with the app connects to the controller. See how Bluetooth access works.

What door hardware does it control?
The 6440ENT is a controller, not a lock body. It drives an electric strike or a magnetic lock fitted to the door. Confirm your existing strike or mag-lock hardware is compatible before ordering; our team can help you check.

Is there a keypad, card reader or key backup on the unit?
No. The 6440ENT has no keypad, reader, fingerprint sensor or cylinder of its own - access is smartphone Bluetooth only. Plan any backup or emergency egress through the door's existing exit hardware as part of the installation design.

Can I manage many doors and users?
Yes. The controller is part of the Master Lock Vault Enterprise system, which is built to manage many locks and many users with individual or group permissions, temporary or ongoing access, and a full audit trail. For a commercial fit-out overview see choosing a platform for commercial use.

Do I need a professional to install it?
Because the controller wires into electric strike or magnetic lock hardware, professional installation is recommended for a reliable, compliant result. Terry's offers site survey and installation services - see our commercial installation services.

Additional Information

The 6440ENT is best understood as an access-control device rather than a standalone lock. It brings a door that already has (or will have) an electric strike or magnetic lock into the Master Lock Vault Enterprise system, so that door can be opened, granted and revoked from the same app used for the enterprise padlocks and Bluetooth key safes. This makes it a natural fit where an organisation is standardising keyless access across gates, plant, key storage and entrances.

Two points worth planning for at the design stage: first, this is a Bluetooth-only device with no on-unit keypad, reader or key override, so backup and emergency egress must be handled by the door's exit hardware; second, the controller must be matched to compatible electric strike or magnetic lock hardware and wired correctly, which is why a professional install is recommended. For the wider decision on access methods, connectivity and where a Bluetooth controller sits among other options, the Smart Lock Buyer's Guide is a good starting point.
