The Lockton Cadell52 (CADELL52-ML60) is a heavy-duty electronic lever lock system from Lockton's E-Series range. This complete kit pairs the Cadell52 smart lock handle set with the SG-ML60 60mm backset mortice lock, providing a ready-to-install solution for commercial and residential doors. The Cadell52 is certified to AS 4145.2 (locksets) and AS 1905.1:2015 (fire door hardware), achieving a physical security rating of SL8 and a durability rating of D8 (500,000 cycles) - making it suited for high-traffic commercial installations including apartment blocks, schools, offices, hospitals and private residences.

Six access methods are supported out of the box: fingerprint biometrics, PIN code, RFID key fob, Bluetooth via the TTLock App (iOS and Android), mechanical key override via a 6-pin C4 rekeyable oval cylinder, and Wi-Fi remote access when paired with an optional TTLock gateway. The TTLock app supports unlimited Bluetooth users, unlimited customised PIN codes, up to 1,000 RFID fobs, and up to 100 fingerprint users. All six access methods are fully functional without a gateway; an optional gateway (G2-G5) adds remote unlock and access management from anywhere in the world. Not sure if you need a gateway? See our Gateway Comparison guide.

The Cadell52 is designed to retrofit over most standard Australian mortice furniture installations, with fixing posts positioned to match standard post spacing. It can replace most existing knobsets, leversets, and deadbolt combinations. Scar plates in three sizes are available separately to cover legacy fixing holes. Available in Matte Black and Satin Stainless Steel. If E-Core or Hallmark (NZ) fire door certification is required, see the Cadell52 ML95 kit.

Fire rating icon
Fire Rated - AS 1905.1:2015 / AS 4145.2
The Cadell52 kit (with SG-ML60 mortice) has been tested and certified by an independent third-party accredited testing laboratory. Fire rating: Firecore (AU) - up to 2 hours. Tested and declared by SIEPER Group. Use on fire doors only with all other hardware in the assembly also fire rated and certified for the Firecore door system. For E-Core or Hallmark (NZ) certification, the Cadell52 ML95 kit carries all three. On a fire door, both sets of expanding fire material must be fitted to the inner plates of both handles, inside the rubber gasket - see page 12 of the Cadell52 User Manual (PDF). Read Lockton's Declaration of Compliance (PDF), or compare every fire door smart lock we stock.

DDA icon Disability Access Compliance (DDA)

IP66 weather protection icon
IP66 Rated - Both Handles
Per the manufacturer's specification and confirmed by distributor SIEPER Group, the Cadell52 carries an IP66 rating on both the external (outside) and internal (inside) handles. IP66 confirms protection against powerful water jets and complete dust ingress protection. This makes the lock suitable for wet or exposed environments - and is a significant advantage where most competitors rate only the external keypad.
Heavy Duty - Built for Commercial Traffic
Lockton designs the Cadell52 as a commercial and domestic electronic lever lock for commercial, education, retail, industrial and medical buildings. Lockton's Declaration of Compliance (PDF) records D8 durability (500,000 cycles) and SL8 physical security to AS 4145.2, and the Cadell52 brochure (PDF) lists solid stainless steel handles on 2mm pressed 304 stainless steel plate furniture for doors of 20-120kg. For what these ratings mean on a busy door, see what heavy duty actually means and why high traffic changes everything.

Battery and Power

App Control and Remote Access (Optional Gateway)

The Cadell52 connects to the TTLock App (iOS and Android) iOS App StoreAndroid Google Play via Bluetooth. Within Bluetooth range, the app can unlock the door, manage user credentials, issue temporary PIN codes, and configure lock settings. No gateway is required for any of these functions.

For remote access from anywhere in the world - including remote unlock, access scheduling, and access history review - an optional TTLock gateway must be connected to your internet router. Five gateway models are available depending on your connectivity requirements. Compare all gateway models in detail or read our Gateway Comparison guide:

All gateways are sold separately. Gateway Bluetooth range to lock: 10-15 metres. The Cadell52 User Manual lists the same five gateways, each with a 3-year warranty, and walks through the G2 set-up on page 19.

Frequently Asked Questions

Does the Cadell52 require a gateway to operate?
No. All six access methods - fingerprint, PIN code, RFID fob, Bluetooth/TTLock App, key override, and the built-in lock functions - work without a gateway. A TTLock gateway (G2-G5, sold separately) is required only if you want to unlock remotely via the internet, schedule time-limited access, or review access history from outside Bluetooth range. Read our full Gateway Comparison guide.
Is the Cadell52 (ML60 kit) suitable for fire-rated doors?
Yes, for Firecore (AU) fire door assemblies up to 2 hours. The CADELL52-BLK-ML60 and CADELL52-SSS-ML60 kits have been tested and certified by an independent accredited laboratory to AS 4145.2 and AS 1905.1:2015. When specifying for fire doors, confirm that all other hardware in the assembly - hinges, seals, closers - is also fire rated and certified for the Firecore system. If E-Core or Hallmark (NZ) certification is required, see the Cadell52 ML95 kit which carries all three certifications.
Will the Cadell52 fit over my existing mortice furniture?
In most cases, yes. The Cadell52 fixing posts are positioned at standard Australian mortice furniture post spacing, so it will drop over most existing commercial mortice furniture installations. If your existing lock leaves larger or off-centre holes, scar plates in three sizes (Art IDs: PS-REC-52-1, PS-REC-52-2, PS-REC-52-3) are available separately to cover legacy fixings cleanly. See also the scar plate guide.
What oval cylinder do I need for a door thicker than 64mm?
The 50mm oval cylinder (Art. 410/50-BLK-KD) supplied in the kit is correct for door thicknesses of 32mm to 64mm. How to measure your backset. For doors 64mm to 90mm thick, order the 62mm oval cylinder (Art. 410/62-BLK-KD) separately. Do not use a cylinder that is too short for the door thickness, as this will prevent the key from correctly actuating the mortice lock cam.
Can the inside handle be converted to a turn snib rather than passage?
Yes. The inside handle comes pre-configured with a flush stainless steel insert for passage function (free egress at all times). The included turn snib kit allows the inside handle to be converted to a turn snib, enabling the inside handle to lock the latch and prevent egress. Important: read about the risks of the internal snib on smart locks before enabling this feature. Both the flush insert and the turn snib kit are included in the box at no additional cost.

Additional Information

Fire Door Installations:
The Cadell52 ML60 kit is certified for use on Firecore (AU) fire door assemblies only - not E-Core or Hallmark (NZ). All hardware in the assembly - hinges, seals, closers, strikes - must also be independently fire rated and suitable for the Firecore door system. Do not install on E-Core or Hallmark (NZ) assemblies with the ML60 kit; use the ML95 kit for those systems. See also: Apartment Fire Doors on the Gold Coast - The one-penetration rule for fire doors - Asbestos risk in Gold Coast fire doors
Oval Cylinder Selection: Not sure what your backset measurement is?
Three oval cylinder scenarios apply to this product: (1) If fitting the cylinder into the Cadell52 outside handle directly (not into the mortice lock), use a 34mm oval cylinder (Art. 410-BLK-KD, not included). (2) If fitting the cylinder into the mortice lock for door thickness 32-64mm, use the 50mm cylinder included in the box (Art. 410/50-BLK-KD). (3) For door thickness 64-90mm, order the 62mm cylinder separately (Art. 410/62-BLK-KD). Using the wrong cylinder length will result in incorrect key function or cam engagement failure.
Retrofit Compatibility:
The Cadell52 is designed to fit over most Australian commercial mortice furniture with standard post spacing. Measure your door before ordering and confirm post spacing against the supplied fitting template before chiselling or drilling. See our DIY installation guide. If the existing lock leaves a hole pattern that doesn't align with the Cadell52 fixing posts, a scar plate is required. Three plate sizes are available - measure the existing hole pattern before ordering.
IP66 on Both Handles: What do IP ratings mean?
IP66 confirms complete protection against dust ingress and protection against powerful water jets from any direction on both the external and internal handles. This is a significant advantage in applications where the internal handle may be exposed to moisture - such as covered external corridors, commercial kitchens, or humid environments. IP66 does not mean submersion-proof - do not immerse the lock in water.
Snug Fit - Rubber Gasket: Read the 3 most common DIY installation mistakes.
The Cadell52 outside handle uses a rubber gasket against the door surface as part of its water-resistant seal. When fitting the outside handle over the oval cylinder, resistance will be felt as the gasket seats - this is normal and expected. Push the handle firmly and evenly until fully seated. Do not use excessive force with tools on the face of the handle; apply pressure to the body only.

Lockton Cadell52 (60mm Mortice) - FAQ, Setup and Owner's Guide

Everything below is here to help you choose, install, set up and live with the Lockton Cadell52 60mm mortice kit. For general smart lock questions see our Smart Lock FAQ (Chapter 13), and for measuring, fitting and choosing see the Smart Lock Buyer's Guide.

Fire Doors and Compliance

Can I fit the Cadell52 ML60 kit to a fire door?
Yes - if the door is a Firecore (AU) fire door. The ML60 kit is fire rated for Firecore door assemblies for up to 2 hours and certified to AS 1905.1:2015 (fire door hardware) and AS 4145.2 (locksets). Every other item of hardware on the door - hinges, seals, closers and strikes - must also be fire rated for the same door system. Start with our guide to fire door core types and why you cannot just swap the lock.
How do I know whether my door is Firecore, E-Core or Hallmark?
Check the door's fire compliance tag - it identifies the door and its fire rating, and the core type decides which Cadell52 kit you need. Our guides show how to identify a fire door, where to find the compliance tag and the common fire door types in Australia. If the tag is missing or you can't read it, talk to us before you order.
My fire door is E-Core or Hallmark (NZ). Which Cadell52 do I need?
The Cadell52 ML95 kit, not this one. The ML60 kit is rated for Firecore (AU) doors only. The ML95 kit, with its 95mm-backset SG-ML95 mortice, is declared for Firecore (AU), E-Core (AU) and Hallmark (NZ) doors, each up to 2 hours - see its fire rating and Declaration of Compliance (PDF). Because the ML95 has a 95mm backset, check your backset first.
Is anything extra required when fitting the Cadell52 to a fire door?
Yes. Lockton's instructions require both sets of expanding fire material to be fitted to the inner plates of both handles, inside the rubber gasket. The step is on page 12 of the Cadell52 User Manual (PDF). We also recommend professional installation on apartment fire doors - see why we do not recommend DIY on apartment fire doors.
What paperwork does Lockton provide for the fire rating?
Lockton publishes a one-page Declaration of Compliance (PDF) for the Cadell52 60mm mortice kit. It states the kit passed the relevant clauses of AS 4145.2 and AS 1905.1:2015, lists Firecore up to 2 hours, and gives the SL8 physical security and D8 durability (500,000 cycles) results. If your certifier, builder or body corporate needs more, contact us and we will help. For what to ask for, see statements of compliance and our fire-rated smart lock certification list.
Can I add a deadbolt or a second lock to my apartment fire door?
Usually not. Most Queensland apartment entry doors are fire doors, and extra penetrations can compromise the door's fire certification. Our guide to the one-penetration principle explains why deadbolts are not compliant and when a fire-rated deadlatch is the compliant option. On most fire doors the better answer is to upgrade the primary lock - which is what the Cadell52 does.
Should I worry about asbestos before drilling an older fire door?
In older buildings, yes - some fire door cores contain asbestos, so have the door checked before any drilling or chiselling. Read the three confirmed risk windows, what to do next and our asbestos FAQ answer.

Access Methods and Credentials

What are the six ways to open the Cadell52?
Fingerprint, PIN code, RFID key fob, the TTLock app over Bluetooth, the mechanical key in the 6-pin C4 oval cylinder, and remote unlock through the TTLock app once an optional gateway is connected. The first five work with no gateway and no internet. Compare credential types in Chapter 03 - access methods side by side.
How many users can the Cadell52 store?
Up to 100 fingerprints and up to 1,000 RFID fobs, plus unlimited Bluetooth app users and unlimited customised PIN codes managed through the TTLock app. PIN codes are 4 to 9 digits long. See fingerprints, IC cards and other credentials in our TTLock guide.
What kinds of PIN codes can I create?
The TTLock app offers permanent, time-limited, one-time, cyclic and customised passcodes, plus an erase code - so you can give a cleaner a weekly code or a guest a code that expires. Our TTLock passcode guide explains each type, the 24-hour activation rule explains the window for using a new code, and the weekly cleaner example shows cyclic codes in practice. The full detail is in the TTLock App User Manual (PDF).
How do I get reliable fingerprint reads?
Enrol each finger in the TTLock app (the Cadell52 steps are on page 17 of the User Manual), capturing the finger at slightly different angles so the reader recognises it from more than one position. Our three-angle enrolment technique walks through it.
Can I add more RFID fobs?
Yes. The kit includes two fobs and the lock stores up to 1,000. Extra Lockton E-Series RFID key fobs are sold separately and are added through the TTLock app - adding a key fob is covered on page 18 of the User Manual. How RFID credentials work is explained in Chapter 03.
Does the Cadell52 have a key override?
Yes. A 6-pin C4 oval cylinder with two keys is included. It is rekeyable and convertible to restricted key profiles, and the key also opens the lock if the batteries go flat. Read what a key override is and where to store the override key.

App, Gateway and Remote Access

Do I need a gateway?
Only for remote access. Everything at the door - fingerprint, PIN, fob, key and app unlock over Bluetooth - works without one. A gateway connects the lock to the internet so you can unlock remotely, manage access and review activity from anywhere. See Bluetooth only vs gateway and do you actually need a gateway?
Which gateway should I choose?
The Cadell52 User Manual lists five TTLock gateways - G2 (2.4GHz Wi-Fi), G3 (Ethernet), G3P (Power over Ethernet), G4 (4G SIM) and G5 (dual-band 2.4GHz / 5GHz Wi-Fi) - each with a 3-year warranty (page 20). The Lockton G2 gateway is the most common residential choice. Compare them in G2 vs G3 vs G4 vs G5 and choosing the right gateway; cross-brand interchangeability is covered there too.
Why won't my gateway connect to Wi-Fi?
The G2 gateway needs a 2.4GHz Wi-Fi network. Routers that combine 2.4GHz and 5GHz under one network name - band steering - are the most common cause of set-up failures and dropouts. See Wi-Fi band requirements, band steering explained and two ways to fix it. The dual-band G5 is the alternative where you can't separate the bands. The G2 set-up steps are on page 19 of the User Manual.
What still works if the internet goes down?
Everything at the door. Fingerprint, PIN, fobs, the key and Bluetooth app unlock all work locally; only remote functions pause until the gateway reconnects. See what happens when the internet goes down and where to place the gateway.
Can the Cadell52 be used for short-stay or holiday rentals?
Yes. With a gateway, TTLock can issue time-limited codes and connect to property management platforms that automate guest access. See PMS platforms that integrate with TTLock, PMS integration in Chapter 14 and what TTLock can do without Wi-Fi. Keep an eye on audit trails for guest disputes.
Where is my TTLock data stored?
That depends on the app platform, not the lock hardware. Our guide to where each smart lock platform hosts its data covers TTLock, and TTLock security considerations lists its published vulnerabilities.
Why does the TTLock app show a Tamper Alert setting?
The Tamper Alert toggle appears across TTLock locks, but on Australian Lockton, McGrath and Austyle hardware it produces phantom alerts - leave it switched off. See how to turn off Tamper Alert in three steps and why it keeps going off.

Power and Batteries

What batteries does the Cadell52 use and how long do they last?
Four 1.5V AAA alkaline batteries, supplied in the box. Lockton quotes about one year at 10 to 20 uses a day. The TTLock app shows the battery level, and the lock gives audio and LED low-battery warnings. See monitoring and choosing batteries and our power and battery FAQs.
What if the batteries go completely flat?
Use the mechanical key. The Cadell52 has no USB-C emergency power port, so the C4 oval cylinder and key are your backup. Keep the key where you can get to it from outside - see storing the override key and what to do when the battery dies.

Installation and Fit

Will the Cadell52 fit my door?
It suits doors 32-60mm thick weighing 20-120kg, with a 60mm backset for the supplied SG-ML60 mortice. Three screw and spindle packs cover 32-40mm, 40-50mm and 50-60mm doors (User Manual page 4). Measure the backset and door thickness before ordering, and check the mortice lever furniture already on the door.
Can I change the handing?
Yes. The handing is set on site - Lockton's procedure is on page 5 of the User Manual, and the SG-ML60 mortice handing reference is on page 7. For left-hand and right-hand basics, see how to determine your door's handing.
What should I know before installing?
Five points from the User Manual: (1) screw the two 30mm posts to the outside handle (page 6); (2) the outside handle is a snug fit over the pre-fitted cylinder, and some gasket resistance is normal (page 2); (3) connect the cable between the handles and seat it in the cable cave (page 9); (4) fit the batteries and test the lock (page 10); (5) on a fire door, fit the expanding fire material (page 12). Mark the door with the 60mm mortice drilling template (PDF), and read the three most common DIY installation mistakes.
Should I install it myself or use a locksmith?
Fire doors, strata buildings and doors that need new mortice preparation are best handled by a licensed locksmith. See when DIY is appropriate, ask us about installation, or book a site survey on the Gold Coast.
How do I fit the turn snib instead of the flush insert?
The turn snib kit is in the box. Its tailpiece is notched for 32-40mm, 40-50mm and 50-60mm doors, and page 13 of the User Manual shows how to fit it. Before you do, read what an internal snib can disable - with the snib fitted, the inside handle can lock the latch and prevent egress.

Suitability

Can the Cadell52 go on a door exposed to the weather?
Yes. Both the outside and inside handles are IP66 rated, which means protection against powerful water jets and dust. IP66 is not immersion protection. See IP ratings explained, and for coastal homes read electronic locks in coastal conditions.
Is the Cadell52 DDA compliant?
The lever handle design complies with AS1428.1-2009 (design for access and mobility), and the clutching lever helps users with limited grip strength. That compliance covers the lever design, not the whole doorway. See what AS1428.1 compliance actually means, certified accessible smart locks and NDIS funding.
Is it tough enough for a busy commercial door?
Yes. The Cadell52 carries a D8 durability rating - tested to 500,000 cycles - and an SL8 physical security rating under AS 4145.2, with solid stainless steel handles on 2mm pressed 304 stainless steel plates. See what the D grades mean, what the SL grades mean and usage frequency and cycle ratings.
What is the difference between the ML60 and ML95 kits?
Same handle set, electronics and access methods - the difference is the mortice and the fire scope. The ML60 kit uses the 60mm-backset SG-ML60 mortice and is rated for Firecore (AU) doors. The ML95 kit uses the 95mm-backset SG-ML95 mortice and is declared for Firecore (AU), E-Core (AU) and Hallmark (NZ). Both come in Matte Black and Satin Stainless Steel.
Is there a Lockton smart lock for a door that is not a fire door?
Yes. The Lockton ELEV64 is an interior lever smart lock with the fingerprint reader built into the lever, and it is not fire rated. For narrow-stile doors there is the ELEV36 for hinged doors and the ELEV36 for sliding doors. All run on the same TTLock app - browse the full Lockton range.
What other fire-rated smart locks do you stock?
Beyond the Cadell52 range, the McGrath Hamilton (also in Satin Nickel) is fire-assessed for Firecore and E-Core doors, with a DDA-compliant lever and fingerprint access, and the McGrath Windsor is a fire-rated keypad smart lock without fingerprint. Both run on the McGrath Locks app, built on TTLock. Browse every fire door smart lock or read the Hamilton in Chapter 05.

Warranty and Support

What warranty does the Cadell52 carry?
Lockton warrants the Cadell52 for 10 years on mechanical components and 3 years on electronic components; batteries are not covered. The TTLock gateways carry their own 3-year warranty. Buy through Terry's and we manage the claim for you - see Returns & Warranty and the Lockton Warranty Statement.

How to Make a Claim

For full returns and warranty claim procedures, visit our Returns & Warranty page - this is kept up to date and is the authoritative reference for current claim steps.

Lockton products are sold exclusively through trade channels. End-users who have received a Lockton product via an installer or trade supplier should contact their installer in the first instance - the trade supplier will liaise with Lockton Security to process the claim on your behalf.

To lodge a warranty claim through Terry's Tradies Pty Ltd and its associated websites, trading names, and subsidiaries (including Gold Coast Smart Locks), please follow these steps:

  1. Contact us with details of the defect and, where possible, installation images.
  2. Supply your proof of purchase (invoice number or receipt).
  3. Provide contact details for claim updates.
  4. A Goods Return Number (GRN) will be obtained from Lockton Security on your behalf.
  5. Package the product securely, include the GRN, and return it as directed. Products returned without a GRN may not be accepted.

Once a correctly submitted claim is assessed by Lockton Security and approved, they will at their own cost and discretion either: repair and return the product; provide a replacement or similar product; supply refurbished goods of equivalent type and quality (covered under the remaining warranty period); or refund the purchase price. If the claim is not approved, Lockton Security will advise in writing and the product will be returned at the customer's expense, or recycled upon request.

Exclusions

The Lockton warranty does not cover:

  • Damage caused by improper use or incorrect product selection
  • Improper installation
  • Fair wear and tear
  • Environmental conditions outside product specifications (e.g. coastal air, high humidity, or exposure to corrosive substances)
  • Products that have been modified, repaired, or altered
  • Use of non-genuine replacement parts or accessories
  • Batteries (no warranty applies)
Australian Consumer Law
Our goods come with guarantees that cannot be excluded under the Australian Consumer Law. You are entitled to a replacement or refund for a major failure and compensation for any other reasonably foreseeable loss or damage. You are also entitled to have the goods repaired or replaced if the goods fail to be of acceptable quality and the failure does not amount to a major failure. The Lockton manufacturer warranty is offered in addition to, and does not limit, these statutory rights.
