The Lockwood 002DX is Lockwood's battery-free keypad deadlatch: press C, enter the code, turn the knob and you are in - no electronics, no wiring, nothing to go flat. This page is the 002-4KDXSC configuration, built for doors that open outwards with a knob on the inside face.
The inside knob gives free, single-action exit - turn and go, no code on the way out - and keeps the internal face compact where a projecting lever would catch on trolleys, bags or passing traffic. The open-out strike arrangement suits doors hung to swing away from you - the pattern common on storerooms, plant rooms and commercial doors that open onto corridors and walkways.
One shared code runs the door, changed at the bench whenever staff move on, and every wearing part - keypad, mounting plate, code tumblers - is stocked as a spare. If your door swings the other way, or you would rather the other handle inside, the Item Code Family table below sorts it in one look: the keypad side is identical on all four 002DX configurations.

Battery free. Hassle free.
The 002DX platform is Lockwood's heavy duty commercial deadlatch - built for doors that get opened all day, every day. The clutching keypad sheds forced attacks instead of absorbing them, and the whole assembly stays serviceable part by part decades into its life. Our commercial guide explains what actually makes a lock heavy duty.
Key Features
- Fully mechanical keypad deadlatch - no batteries, no wiring, nothing to charge
- Single programmable 4 to 6 digit code - each digit used once, entered in any order
- Built for opening-out doors with a knob on the inside face
- Free single-action exit through the inside knob at all times - no code to get out
- Clutching keypad knob freewheels without a valid code, so forcing it transfers no load into the mechanism
- Code cancels automatically as the knob is operated - never left sitting on an entered code
- Holdback: rotate the inside knob past 90 degrees to hold the latch open
- 18mm throw stainless steel bolt, 60mm backset, suits 32-45mm doors
- Keypad, mounting plate and code tumblers all replaceable as stocked spare parts
Item Code Family - Lockwood 002DX Deadlatch Range
All four locks share the same keypad, deadlatch case, 60mm backset and Satin Chrome finish. The item code simply sets which way your door opens and what you grab on the inside face - pick the row that matches your door and you have the right lock. This page is the 002-4KDXSC, the bolded row.
No electronics, no batteries, no wiring. The code lives in a mechanical tumbler chamber, and the lock runs the same on day one and day ten thousand.
Fire Door Compliance
The Lockwood 002-4KDXSC should not be described as automatically fire compliant in every installation. Fire performance belongs to the complete tested doorset - the door, frame, strike arrangement, latch preparation and the installation itself - so no lock is fire compliant on its own.
Two Digital DX details are safety-critical on fire doors. First, Lockwood's service information states the keypad must be fitted without the rubber mounting pad - small installation details like this can affect the compliance of the finished doorset. Second, the holdback function must never be engaged on a fire door - a held-open latch defeats the self-latching a fire door relies on. Our guide explains why hold-back is never used on fire doors.

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.
Operation
- External entry: press C to clear anything already entered, press your code digits, then turn the keypad knob - the deadlatch retracts and the door opens
- Auto reset: the code cancels automatically as the knob is operated, so the lock is never left sitting on an entered code
- Internal exit: the inside knob opens the door in one action, every time, with no code
- Relatching: the deadlatch relatches automatically as the door closes behind you
- Clutch protection: without a valid code the keypad knob freewheels rather than driving the latch, so a forced attack transfers no load into the mechanism
- Holdback: rotate the inside knob past 90 degrees to hold the latch open; operate the knob again to release it - and never engage it on a fire door
Code Control - How the Code Works and How to Change It
The 002DX runs one shared 4, 5 or 6 digit code. The code lives in a mechanical tumbler chamber behind the keypad - there is no memory chip and nothing to reset electronically. Because it is a chamber rather than a sequence, each digit is used once per code and the digits can be pressed in any order; the C button always clears a wrong entry and cannot be part of the code. The lock is supplied with a factory-set code - change it to your own at installation. Our pillar guide explains how the coding chamber works and why the digits are order-independent.
Changing the code is a bench job, and honestly a fiddly one: the keypad comes off the door, the backplate comes off, and the code tumblers are repositioned before it all goes back together. The full procedure is on page 4 of the Lockwood DX Digital Service Manual. We have written the whole thing up in plain English too - the Lockwood DX section of our code-changing guide, the shared bench method, the classic traps, how long a code change really takes, and the one rule that saves callouts: test the new code five times with the door open. Spare red (SPDX-42) and blue (SPDX-43) code tumblers are stocked - our spares rundown covers when you need them.

Frequently Asked Questions
No. It is a fully mechanical lock - there is nothing to charge, nothing to wire and nothing to go flat. The code is held in a mechanical tumbler chamber, not a circuit board.
One shared code, which is exactly right for staff doors, plant rooms and service areas - everyone authorised uses the same code and it gets changed when staff move on. If you need a code per person or an audit trail, a mechanical lock is the wrong tool: our pillar guide covers the honest limitations and when a smart lock earns its place instead.
No - it is a bench job. The keypad comes off the door, the backplate comes off, and the code tumblers are repositioned. Budget for a fiddly half hour the first time: follow page 4 of the Service Manual or our bench method guide, and test the new code five times with the door open.
No 002DX variant has one - entry is code only, with free exit from inside. If a keyed override matters on your door, the DX mortice family offers it: the 3572DXKO includes the override cylinder, and the 3572DXKONCYL is the same lock supplied without the cylinder. Our commercial guide covers when key override earns its place.
The 002DX suits doors 32mm to 45mm thick on a 60mm backset, and this 002-4KDXSC configuration is built for opening-out doors with a knob inside. If you are replacing an existing deadlatch, measure first - our guide shows how to measure your backset and why the wrong backset hurts.
Additional Information
- Door preparation matters: the spindle is cut to length to suit the door, and a frame strengthener is typically fitted at the strike to carry the load - accurate prep is what makes these locks run sweetly for years.
- Serviceable platform: the keypad assembly (SPDX-50SC and SPDX-20SC), the SPDX-520 mounting plate and spare code tumblers are all stocked - a large part of why mechanical digital locks out-live sealed electronic units. Our guide covers why spare parts matter.
- Borg cross-compatibility: the Borg BL002KIT adaptor kit fits Borg 2000 and 4000 series keypads to the 002 deadlatch case - useful for back-to-back conversions - and the matching Borg spindle is stocked separately.
- Coastal care: the 25 year mechanical warranty excludes corrosion damage from coastal air, salt spray and high humidity, so near the water give the keypad and furniture a regular wipe-down with mild soap and water - no harsh chemicals. Our brand corrosion comparison is the honest read on salt exposure.
- Battery-free by design: Chapter 16 of our Buyer's Guide explains what a mechanical digital lock is and how the Lockwood DX range compares with Borg and Carbine.

Lockwood 002DX Deadlatch Family - FAQ, Setup and Owner's Guide
Everything owners, installers and specifiers ask about the 002DX deadlatch, in one place. This guide covers all four configurations - and this page is the 002-4KDXSC, with a knob inside for opening-out doors. For the wider battery-free picture, start with Chapter 16 of our Buyer's Guide (Mechanical Digital Locks) and the pillar guide What Is a Mechanical Digital Lock?.
Codes and Everyday Use
Press C to clear anything already entered, press your code digits, then turn the keypad knob - the deadlatch retracts and the door opens. The code cancels automatically as the knob is operated, so the lock is never left sitting on an entered code, and the deadlatch relatches behind you as the door closes.
That is the clutching action, and it is deliberate. Until a valid code is entered, the knob freewheels rather than driving the latch, so forcing or wrenching it transfers no load into the mechanism. It is one of the reasons these locks survive high-use commercial doors for decades.
Any 4, 5 or 6 digit code, with each digit used once per code. Because the code lives in a tumbler chamber rather than a sequence, the digits are order-independent - 2580 and 0852 open the same chamber - so pick digits, not patterns. The C button is the clear key and can never be part of the code. The mechanics are explained in our coding chamber explainer and any-order codes note.
It is a fiddly bench job, not an on-door job: the keypad comes off the door, the backplate comes off, and the code tumblers are repositioned, then everything goes back together. Follow page 4 of the Service Manual or our bench method guide, watch the common traps, and budget the time realistically - our guide covers how long a code change actually takes. And always: test the new code five times with the door open.
You are locked out of the keypad side - the inside knob still opens the door from within, and there is no key override on the 002DX family. A locksmith can recover the situation: the keypad comes off the door and the chamber can be read and re-set. If you are local, call Terry's; spare tumbler kits are covered in our spares rundown.
One - the 002DX holds a single shared code, which is exactly right for staff doors, plant rooms and service areas where everyone authorised uses the same code and it gets changed when staff move on. If you need a code per person, or an audit trail of who came through, a mechanical lock is the wrong tool - our pillar guide covers the honest limitations and when a smart lock earns its place instead.
Choosing Your Variant
Two questions settle it: what do you want on the inside of the door, and which way does the door swing? This page is the 002-4KDXSC - knob inside, for doors opening outwards. The other three configurations: 002-1LDXSC (lever, open-in), 002-1KDXSC (knob, open-in), 002-4LDXSC (lever, open-out). The keypad side is the same on all four - only the internal furniture and the strike arrangement change.
You do not order it by hand. The 002 deadlatch platform is made to suit left- and right-hung doors by rotating the bolt head - but that is a bench adjustment done during installation, not a user-serviceable on-door flip, so treat it as the installer's job. What you must get right at ordering is the door swing (opening-in vs opening-out) and the inside handle. If handing conventions are new to you, our guide covers how to determine handing and which locks are field-reversible and which are not.
No 002DX variant has a key override - entry is code only, with free exit from inside. If a keyed override matters on your door, the DX mortice family offers it: the 3572DXKO includes the override cylinder, and the 3572DXKONCYL is the same lock supplied without the cylinder for sites keying it into an existing system. Our commercial guide covers when key override earns its place.
The 002DX is a deadlatch: it self-latches locked behind you every time, which is the behaviour shared-access and staff doors usually want. The 530DXSC is the DX keypad on a 530 tubular latch entrance set - the alternative for standard entrance preparations, with a double keypad version for coded entry from both sides. For the wider format question, read Latch vs Bolt Mechanical Digital Locks, and for how the 002DX and 530DX sit within the Lockwood range, our three-brand comparison covers the 002DX and the 530DX.
Installation and Door Prep
The 002DX suits doors from 32mm to 45mm thick, on a 60mm backset. If you are replacing an existing deadlatch, measure before you order - two minutes with our backset measuring guide settles it, and here is why the wrong backset hurts. Doors outside the thickness range are a talk-to-us-first situation, not an after-delivery discovery.
On a fresh timber door, a confident DIYer with the DX Digital Service Manual in hand can do it - but the details matter: the door preparation must be accurate, the spindle is cut to length to suit the door, and a frame strengthener is typically fitted at the strike to carry the load. On a door that already has hardware, a fire door, or anything metal-framed, use a locksmith - the prep tolerances are what make these locks run sweetly for years. Local to the Gold Coast?

Fire Doors and Egress
Not automatically - fire performance belongs to the complete tested doorset (leaf, frame, lock, strike, preparation and installation together), so no lock is fire compliant on its own. Two Digital DX details are safety-critical: the keypad must be fitted without the rubber mounting pad on fire door applications (Lockwood service information), and the holdback must never be engaged on a fire door. Bring us the approved fire door schedule (or a photo of the door tag) and we will give you a straight answer. Background reading: our fire door compliance guide, Fire Door Types and Lock Certification in Australia, or browse the locks we list for fire doors.
Its behaviour is right for it: exit through the inside knob is single-action and never needs a code, at all times - the pattern egress paths demand. What the lock cannot do is make the doorset compliant by itself; that certification belongs to the whole tested assembly. Our commercial guide explains how exit paths are assessed.
Rotating the inside knob past 90 degrees holds the latch open - handy for trading hours, deliveries and move-in days, so the door is not relatching on every trip. Use it deliberately and take it off when you leave. Read Passage Mode vs Holdback Mode first, including why hold-back is never used on fire doors.
Care, Coastal Conditions and Warranty
Wash it. The 25 year mechanical warranty excludes corrosion damage from coastal air, salt spray and high humidity, so near the water a regular fresh-water wipe-down of the keypad and furniture - mild soap and water, no harsh chemicals - plus Lockwood's published care guidance at lockweb.com.au is what keeps both the finish and the claim alive. For an honest look at how the three brands compare near salt, read our brand corrosion comparison.
The DX keypad assembly itself is replaceable (SPDX-50SC and SPDX-20SC), the SPDX-520 mounting plate is stocked, and spare code tumblers are available. The exploded parts diagram and orderable variants for the whole 002 family are on page 8 of the DX Digital Service Manual. This serviceability is a large part of why mechanical digital locks out-live sealed electronic units.
