Lockwood Digital DX Mechanical Keypad Mortice Lock – 3572DX – 60mm Backset
The Lockwood 3572DX Digital DX Mortice Lock is a mechanical keypad access control lock designed for commercial doors where secure keyless entry is required without electrical wiring or batteries.
This lockset combines the Lockwood 3572 Series cylinder mortice lock, Lockwood 1800 or 2800 series door furniture and a mechanical Digital DX keypad access pad to create a robust keyless access solution.
The Digital DX system operates entirely mechanically, meaning the lock continues functioning regardless of electrical power availability. This makes it suitable for many commercial and institutional environments where reliability and simplicity are priorities.

Fire Door Compliance
The Lockwood 3572DXLSC and 3572DXRSC are commonly specified on fire door assemblies, but they should not be described as automatically fire compliant in every installation. Fire performance depends on the complete tested doorset, including the door, frame, mortice lock, furniture, handing, latch preparation and installer compliance.
These left-hand and right-hand 3572DX locksets sit within the broader Lockwood mortice lock platform, where fire testing relates to the full door assembly rather than the lockset in isolation. For Digital DX fire door applications, the rubber mounting pad must not be fitted where manufacturer instructions require its omission.

Important: Always confirm suitability against the approved fire door schedule, the door manufacturer’s requirements and the complete tested hardware combination. If you are not sure, Contact Us before ordering.
