The Lockwood 530DXSC/PADSX2 is the double keypad version of the 530 Digital DX Entrance Set - a fully mechanical keypad lock with a Digital DX code pad on both faces of the door, running on the supplied 60mm Lockwood 530 tubular deadlatch. There are no batteries, no wiring and no electronics: the code lives in a mechanical tumbler chamber inside each keypad.
Where the standard 530DXSC single keypad set gives you coded entry from outside and a free handle inside, this PADSX2 version requires the code in both directions - press C, enter the code, turn the knob, from whichever side of the door you are on. That makes it the pick for doors where movement has to be controlled both ways, and the wrong pick for any escape route - see Fire Doors and Egress below before specifying.
It is not a smart lock. There is no app, no per-user codes, no audit trail and nothing to charge or pair - and for a stockroom or plant-room door that is precisely the appeal. New to battery-free keypad locks? Our guide What Is a Mechanical Digital Lock? explains how the coding chamber inside works.

Battery free. Hassle free.
The /PADSX2 suffix means a Digital DX keypad on each face of the door, so nobody passes through in either direction without the code. That is the right tool for server rooms, pharmacy and medication stores, cash handling areas and stock-shrinkage doors where staff movement has to be controlled both ways - the same logic behind the dual-keypad Carbine CDL7200LL-KDSC-HD. On gates, back-to-back keypads also solve the reach-over problem - our guide Why Double-Sided Locks Are a Smart Choice for Gates explains when two keypads beat one. If you want coded entry but free exit, the single keypad 530DXSC is the version to buy.
Key Features
- Fully mechanical double keypad entrance set - no batteries, no wiring, no electronics to fail
- Digital DX code pad on both faces of the door, so entry and exit are both code-controlled
- One shared code across both keypads - factory set at 4 digits, changeable to any 4, 5 or 6 digit code
- Operation from either side: press the C button to clear, enter the code, then turn the knob
- The entered code cancels automatically when the knob is released, so the door is never left standing on an open code
- The keypad knob freewheels until a valid code is entered - a clutching action that protects the internal parts if someone forces the knob
- Supplied with the 60mm Lockwood 530 tubular deadlatch (brass, 13mm projection); 70mm and 127mm latch kits available separately
- Suits right-hand or left-hand doors, opening inwards or outwards - no handed ordering required
- Field-serviceable: replacement keypads and spare code tumblers keep the lock in service for decades
Need a Complete Internal/External Package?If you want a single box that includes both the Digital DX keypad for the outside and a matching internal lever or knob - ready to install with nothing else to source - the Lockwood 002DX deadlatch family is the one to look at. It is also a common choice for 
apartment fire doors, where the 002 deadlatch combined with coded entry and free internal exit meets the egress requirements of most tested doorset schedules - always confirm against your building's approved fire door schedule before ordering.
- 002-1LDXSC - Lever inside, door opens inwards
- 002-1KDXSC - Knob inside, door opens inwards
- 002-4LDXSC - Lever inside, door opens outwards
- 002-4KDXSC - Knob inside, door opens outwards
The key choice is which way your door opens (inwards or outwards) and whether you prefer a lever or knob on the inside face. Not sure? Contact Us and we will confirm the right variant for your door.
An all-mechanical keypad set designed for frequent daily use in commercial environments - the same DX keypad hardware that serves the Lockwood mortice and 002 deadlatch ranges.

Decoding Lockwood Model Numbers
Lockwood's DX codes look cryptic, but they read cleanly once you know the pattern. Taking 530DXSC/PADSX2 from left to right:
In the mortice DX families the first digit steps through the backset instead (3572, 4572 and 5572 are the same lock at 60, 89 and 127mm) - the full plain-English decoder lives on our 5572DX page, and the spare-part code addendum (SPDX- and SP10000- prefixes) is decoded on the SPDX-20SC keypad page. Lockwood's own ordering procedure for the 002 and 530 Digital DX hardware codes - including the /PADSX2 double keypad option - is on the last page of the catalogue excerpt.
Code Control - How the Code Works and How to Change It
The set ships with a factory 4 digit code, which you can change to any 4, 5 or 6 digit code of your own. The code lives in a mechanical tumbler chamber behind each keypad - there is no memory chip and nothing to reset electronically. Because it is a chamber rather than a sequence, each digit can be 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. Our pillar guide explains how the coding chamber works and why the digits are order-independent.
One point specific to this double keypad set: because there is a coding chamber in each pad, changing the code means recoding both keypads at the bench and keeping them matched - this is a single-code system, so the two pads must always carry the same code. It is a fiddly job (small tumblers, and the sequence matters) but entirely doable with the supplied kit and the instructions in front of you. The full procedure is on page 4 of the Lockwood DX Digital Service Manual; our plain-English write-up covers the Lockwood DX procedure, the shared bench method, how long to allow, and the one rule that saves callouts: test the new code five times before you close the door - on this lock, from both sides.

Fire Doors and Egress - Read Before Specifying
This double keypad set must never be fitted to a fire door or any required escape route. With a keypad on both faces, leaving through the door requires the code - there is no free, single-action exit, and code-controlled egress is prohibited on fire and escape doors. This is the same rule that applies to every dual-keypad mechanical lock; the canonical explanation is on our Carbine dual-keypad page.
The 530 Digital DX Entrance Set family does carry genuine fire heritage - the set is fire rated to 2 hours under AS 1905.1 (see page 4 of the catalogue excerpt) - but that path belongs to the single keypad 530DXSC, where the inside knob turns freely without a code. Even then, fire performance always belongs to the complete tested doorset, never to the lock in isolation - our guides explain the ground rules: Apartment Fire Doors on the Gold Coast - What Locks Are Actually Compliant? and Fire Door Types and Lock Certification in Australia.
Important: If you are not sure whether your door is a fire door or part of an escape route, Contact Us before ordering - and before anyone drills. On older Gold Coast fire doors, read why your locksmith warns you about asbestos before drilling.

Frequently Asked Questions
PADSX2 means the set is supplied with a Digital DX keypad on both faces of the door - pads x 2. Unlike the standard 530DXSC (single keypad, free inside handle), this version requires the code to pass through in either direction. If you only want coded entry from outside with a free handle inside, the single keypad 530DXSC is the version to order.
No. With a keypad on both faces, exiting the door requires the code - there is no free, single-action egress. Code-controlled egress is not permitted on fire doors or required escape routes under AS 1905.1. If you need a fire-door-suitable entrance set with coded entry and free exit, the single keypad 530DXSC is the one to specify - always confirming against your building's approved fire door schedule.
No. This is a single-code mechanical system - both keypads share one code, and the coding chambers must be set identically at the bench. There is no way to program separate codes for the external and internal pads. If individual access control or separate credentials are needed, a smart lock is the right tool - see the limitations of mechanical digital locks.
No - it is fully mechanical. There are no batteries to replace, no wiring to run and no electronics to fail or update. The code lives in a mechanical tumbler chamber behind each keypad, and the whole mechanism is driven by the knob. This is exactly the appeal for plant rooms and utility doors that see heavy daily use and cannot afford an electronic failure.
The set is supplied with the 60mm Lockwood 530 deadlatch. If your door requires a different backset, order the 70mm latch (530-222SC) or 127mm latch (530-225SC) separately. Not sure which backset your door needs? Our guide to measuring your lock backset shows you in two minutes.

Lockwood 530DXSC/PADSX2 - FAQ, Setup and Owner's Guide
Everything buyers, installers and owners ask about the double keypad 530 DX entrance set - from specifying the right door to recoding both chambers. General mechanical digital questions are answered in our mechanical digital pillar guide and in Chapter 16 of the Buyer's Guide.
Access and Codes
Both keypads carry a mechanical tumbler chamber. To open the door from either side, press C to clear any partial entry, type your code, then turn the knob. The code cancels automatically when you release the knob, so the door always re-locks. Because both chambers must hold the same code, the lock effectively enforces a single shared credential - no one passes through without entering it. The mechanism is explained in depth in our guide to how the coding chamber works.
No. This is a single-code mechanical system. Both chambers must be recoded to the same code at the bench - there is no way to run different credentials on the two faces. If per-user codes, individual permissions or different codes per direction are needed, a smart lock is the correct tool. We explain this honestly in the limitations of mechanical digital locks and in Chapter 16.
Yes - both keypads must be recoded at the same time. Remove both from the door, use the supplied code change kit to reposition the tumblers in each chamber to the same new code, then refit both before testing. The procedure is on page 4 of the DX Digital Service Manual. Our plain-English write-up covers the Lockwood DX procedure, the bench method step by step, and the critical rule: test the new code five times from both sides before closing the door.
Any four, five or six digit combination where each digit appears only once - digits 1 through 10 (10 is the zero key), plus X, Y, Z and C. The C button is the clear key and cannot form part of the code. Because the chamber is order-independent, pressing 1-3-5-7 is the same as 7-5-3-1; the lock detects the combination, not the sequence. This is covered fully in our guide on why mechanical digital codes are order-independent.
Fire Doors and Egress
A fire door must allow free, single-action egress at all times. With a keypad on both faces, the inside face requires the code to exit - that is code-controlled egress, which is prohibited. The 530 family's 2-hour fire rating (AS 1905.1) belongs to the single keypad 530DXSC, where the inside handle always turns freely. This is the same rule for all dual-keypad mechanical locks - the full explanation, with the Warringtonfire assessment context, is on the Carbine dual-keypad page. Our broader fire door guides: What Locks Are Actually Compliant on Gold Coast Fire Doors and Fire Door Types and Certification in Australia.
Any commercial or internal door where movement in both directions needs to be code-controlled and a fire/escape rating is not required: server rooms, medication stores, pharmacy dispensaries, cash handling areas, stock-shrinkage doors, and back-of-house access areas. Gates are also a natural fit - two keypads eliminate the need to reach over a gate or fence. See our guide on why double-sided locks are a smart choice for gates.
Installation
The standard spindle suits doors 33-45mm thick. For doors 46-55mm, order the SP10000-1227ZP extended double-digital spindle alongside the lock. Doors thicker than 55mm need a different solution - Contact Us before ordering. How to measure: Chapter 02 of the Buyer's Guide.
No - the 530 DX entrance set suits both left-hand and right-hand doors, opening inwards or outwards, with no handed ordering. This is different from the mortice DX range (3572DX, 5572DX) which must be specified left or right at order time. If you want the background on how door handing works in Australia, see Understanding Door Handing in Australia.
Order a different latch separately. The 70mm latch (530-222SC) and the 127mm latch (530-225SC) both fit the same entry set. Not sure what backset your door has? Our backset measuring guide shows you in two minutes.
Servicing and Spares
Replacement keypads - SPDX-20SC and SPDX-50SC - suit the DX range; check the 530 exploded view to confirm which part suits your specific assembly before ordering a non-returnable replacement. Spare red (SPDX-42) and blue (SPDX-43) code tumblers are also stocked - see the spare tumblers section of our code-changing guide. This serviceability is one of the strongest arguments for the Lockwood DX range over cheaper sealed alternatives - our blog explains why trade-grade mech-digi beats hardware store imitations.
A freewheeling knob is almost always the clutch doing its job, not a fault. The DX knob freewheels until a valid code engages it for one turn; if it freeweheels after you've entered what you believe is the correct code, suspect a mis-entry first (try again from a fresh C press), then consider whether the code may have been accidentally changed. If the knob engages but the latch still sticks, check for latch-bolt binding against the strike and that the door hasn't swollen in the frame. The most common genuine fault is a worn or damaged coding chamber - the fix is a replacement keypad, not a new lock.
Choosing and Comparing
One keypad vs two. The 530DXSC has a code pad on the outside only - you unlock with the code from outside, and the inside knob always turns freely. The 530DXSC/PADSX2 (this product) adds a second code pad on the inside face, so both directions require the code. The PADSX2 adds bidirectional control but removes free egress - which rules it out for fire doors and escape routes.
Both are dual-keypad mechanical sets requiring the code in both directions, and neither suits fire or escape doors for that reason. The key differences: the Carbine uses BCA-compliant levers (AS 1428.1 lever accessibility both faces), is salt-spray tested to AS 4145.2 C7-High for exposed coastal use, and has a security break-point lever - making it the pick for outdoor, coastal or accessible-door applications. The Lockwood 530 is a lighter tubular deadlatch format with lower door prep requirements. The full brand breakdown is in Lockwood vs Borg vs Carbine and Chapter 16 of the Buyer's Guide.
Zero electronics to fail, charge or update. High-traffic doors like server rooms and medication stores can cycle dozens of times a day - a mechanical lock is indifferent to that load where an electronic lock needs battery management, firmware updates and sometimes connectivity. The trade is no audit trail, no individual credentials and no remote access. The honest read is in the limitations section of our mechanical digital guide; the commercial depth is in Heavy Duty Commercial Mechanical Digital Locks.
