The Lockton Cadell52 (CADELL52-ML95) 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-ML95 95mm 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. For the 60mm backset variant, see the Cadell52 ML60 kit.

Fire Rated - AS 1905.1:2015 / AS 4145.2
The Cadell52 kit (with SG-ML95 mortice) has been tested and certified by an independent third-party accredited testing laboratory. Fire ratings: Firecore (AU), E-Core (AU), and Hallmark (NZ) - all 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 specific door system. The 95mm mortice variant carries the broadest fire certification in the Cadell52 range - covering Firecore, E-Core and Hallmark, while the ML60 is Firecore-only. When fitting to 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 user manual.

Disability Access Compliance (DDA)
- The Cadell52 lever handle design complies with the disability access requirements of AS1428.1-2009 (DDA) (Design for access and mobility).
- The clutching lever handle assists users with limited grip strength or reduced manual dexterity.
- DDA compliance relates to the lever handle design only and does not imply full building access compliance for the complete installation. Read: Smart Locks for NDIS, DDA & Accessibility
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.

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 for guidance on when one is needed.

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.

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.

Fire Doors and Compliance
Which fire doors is the Cadell52 ML95 kit suitable for?
The ML95 kit is declared for Firecore (AU), E-Core (AU) and Hallmark (NZ) fire door assemblies for up to 2 hours, against AS 1905.1:2015 and AS 4145.2. That is the broadest fire coverage in the Cadell52 range - the Cadell52 60mm mortice kit is declared for Firecore only. Not sure which core your door has? Chapter 05 covers how to identify a fire door and the fire door core types, or find the door's fire door compliance tag. The full declaration is in the Cadell52 ML95 Declaration of Compliance (PDF).

Is there anything special about fitting the Cadell52 to a fire door?
Yes. 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 user manual. Every other item of hardware on the door - hinges, closer, seals and strike - must also be fire rated for that door system, because fire certification covers the whole doorset rather than the lock alone (how AS 1905.1 certification works). We do not recommend DIY on apartment fire doors, and in older Gold Coast buildings the door core can contain asbestos - read the three risk windows before anyone drills. Our supply and installation service covers fire door fits.

What paperwork can I give my building certifier?
Start with the Cadell52 ML95 Declaration of Compliance (PDF). It is issued by SIEPER Group, Lockton's distributor, and states that the kit was tested or assessed by an accredited third-party laboratory and passed the relevant clauses of AS 4145.2 and AS 1905.1:2015, listing the fire door types and the SL8 and D8 ratings. The declaration describes fire performance as "up to 2 hours" rather than stating a Fire Resistance Level (FRL), so if your certifier or fire engineer needs the laboratory report or an FRL for a specific doorset, ask our team and we will request it from the supplier. Our guide to statements of compliance explains what a well-formed declaration contains, and fire-rated smart lock certification lists the documents we hold by brand.

Can I add a deadbolt to an apartment fire door as well?
Usually not. On Queensland apartment fire doors the one-penetration principle generally rules out a separate deadbolt, and deadbolts are not compliant as secondary locks on those doors. The better approach is to upgrade the primary lock - which is what the Cadell52 kit does, replacing the existing mortice lock and furniture. Work through the four strata checks and get body corporate approval first.

Access and Credentials
How many users and credentials can the Cadell52 hold?
Through the TTLock app the lock supports unlimited Bluetooth users (eKeys), unlimited customised PIN codes of 4 to 9 digits, up to 1,000 RFID fobs and up to 100 fingerprints, plus the 6-pin C4 mechanical key. Two fobs come in the box and extra Lockton RFID fobs are sold separately. For how each method behaves day to day, see access methods compared.

How do I set the lock up and add fingerprints, codes and fobs?
Setup runs through the TTLock app, and pages 15 to 18 of the user manual walk through it: download the app and register, add the lock and become its administrator, then change the master passcode before anything else. Fingerprints, passcodes and fobs are then added from the app. For more reliable fingerprint reads use the three-angle enrolment technique, and keep the TTLock app user manual handy for everything else.

What kinds of PIN codes can I give other people?
TTLock offers six passcode types - permanent, time-limited, one-time, cyclic, customised and erase - so a cleaner can have a code that works on set days and a tradesperson a code that expires tonight. Two things catch people out: the 24-hour activation rule for new codes, and the Erase code. Our cyclic passcode example shows a recurring weekly setup.

Should I fit the turn snib or keep the flush insert?
The inside handle ships with the flush stainless steel insert fitted, giving passage function - free egress at all times. The turn snib kit in the box converts the inside handle to a turn snib. The snib tailpiece is notched for the three door thickness ranges (user manual page 13). Before fitting it, read about the real-world problems internal snibs cause on smart locks, particularly on rental and short-stay properties.

Remote Access and Gateways
Do I need a gateway?
No. Fingerprint, PIN, fob, key and Bluetooth app control all work locally with no gateway and no internet. A gateway adds remote unlock, remote code management and access history from anywhere - what changes when you add a gateway is set out in Chapter 14. If the internet drops, local access keeps working.

Which gateway suits the Cadell52?
The user manual lists five TTLock gateways (page 20): 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. We stock the Lockton G2 Gateway, the most common home choice. The G2 connects to 2.4GHz Wi-Fi only - if your router uses band steering, read the G2 Wi-Fi band note first. The G2 vs G3 vs G4 vs G5 comparison covers the differences, and browse all gateways and bridges.

How far can the gateway be from the lock?
Plan for 10 to 15 metres. The gateway talks to the lock over Bluetooth, so walls and obstructions between them matter. Gateway placement in Chapter 08 and where to position the gateway cover it in detail; if the connection keeps dropping, see why smart locks drop off Wi-Fi.

Should I turn on Tamper Alert in the TTLock app?
No - leave it off. The setting appears in the TTLock app, but Lockton hardware does not support it, and switching it on produces phantom alerts. See how to turn off Tamper Alert and why it keeps going off.

Power and Batteries
What batteries does it use and how long do they last?
Four 1.5V AAA alkaline batteries, included. Expect roughly 12 months at 10 to 20 uses a day - heavier use shortens that (battery life, the honest version). The TTLock app shows the battery level whenever you connect over Bluetooth, and the lock gives audio and LED low-battery warnings. Reading a low-battery fault correctly saves a lot of head-scratching.

What happens if the batteries go flat?
Use the key. The Cadell52 has no USB-C emergency power port, so the supplied C4 key is your way in - keep one outside the house, not inside it. What to do when the battery dies walks through it. Browse other smart locks with a backup key.

Installation and Fit
What door thickness does it suit, and which screw pack do I use?
32 to 60mm, using one of the three screw and spindle packs in the box - one each for 32-40mm, 40-50mm and 50-60mm doors. For the mortice installation the packs use split spindles (25, 30 and 35mm) with M5 x 45, 50 and 60mm screws; page 4 of the user manual shows them. Measure first with our door thickness guide. The included 50mm cylinder suits standard doors; thicker doors need the 62mm cylinder (Art. 410/62-BLK-KD), sold separately - see the oval cylinder question in the main FAQ.

Is 95mm the right backset for my door?
The ML95 kit's SG-ML95 mortice has a 95mm backset - measured from the door edge to the centre of the spindle. Check yours before ordering with how to measure your backset. If your door takes 60mm, the Cadell52 60mm mortice kit is the one to buy (Firecore-only for fire doors).

Can I change the handing?
Yes. Page 5 of the user manual shows the handing as supplied and the slider procedure for changing it. If you are unsure which hand your door is, see how to determine your door's handing.

How do the two handles connect through the door?
Two 30mm posts screw to the outside handle, the split spindles pass through the mortice, and the outside handle's cable runs through the door and connects to the inside handle; the manual shows where the cable sits (the "cable cave") before the handles are screwed together. Pages 6 to 9 of the user manual illustrate each step. The outside handle's rubber gasket gives noticeable resistance as it seats - that is normal (user manual page 2).

Will it cover the holes from my old lock?
In most cases the Cadell52 lines up with standard Australian mortice furniture, and Lockton's PS-REC-52 scar plates come in three sizes - 280 x 70mm, 286 x 76mm and 296 x 86mm, in stainless or black - to cover what it does not. Plates are sold individually, so order one for each door face you need covered. Our scar plate guide lists the Lockton range; check the 95mm drilling template against your door before drilling. More options in scar and adaptor plates.

Can I install it myself?
A handy DIYer can fit it to a door already prepared for a mortice lock using the template and manual, but read the three most common DIY mistakes first and check when DIY is and is not appropriate. For fire doors, strata buildings and commercial sites, use a licensed locksmith - our advice and installation team can supply and fit it. If the lock misbehaves after fitting, poor door preparation is the usual cause.

Suitability and Comparisons
Can it go on an exposed door?
Both the outside and inside handles are rated IP66 - protection against dust and powerful water jets - so it handles a wet or exposed doorway better than most smart locks, which rate only the outside unit. IP66 is not submersion-proof. See what IP ratings mean and our front door smart locks.

How will it cope near the coast?
Lockton does not quote a salt spray test figure for the Cadell52, so treat beachfront and salt-air doorways with care and wipe the handles down regularly. Our notes on coastal environments and Queensland conditions explain what salt air does to door hardware.

Is it suitable for Airbnb and short-stay rentals?
Yes - TTLock is widely used for short-stay. Even without a gateway the app can issue time-limited codes (what TTLock can do without Wi-Fi); with a gateway and a property management system, guest codes can follow each booking (how TTLock automation really works, PMS integration). Compare the options in Igloohome vs TTLock.

Is it suitable for NDIS and accessible housing?
The Cadell52's clutching lever is designed to AS1428.1-2009 (design for access and mobility), and a resident or carer can use a fob, fingerprint or phone instead of a key. DDA compliance relates to the lever design, not the whole doorway. See what AS1428.1 compliance actually means and NDIS funding.

How does the Cadell52 compare with the other Lockton E-Series locks?
The ELEV36 is Lockton's narrow euro-mortice smart lock for hinged and sliding doors; the ELEV64 is a fingerprint lever lock for interior doors. Neither carries a fire rating - the Cadell52 is the E-Series choice for fire doors. All three run on TTLock and work with the Lockton G2 gateway. See the full Lockton range.

Is there a lower-cost fire-rated smart lever lock?
Yes - the McGrath Hamilton (also in Satin Nickel) is a lower-cost TTLock-platform lever lock with a fingerprint reader and a DDA-compliant lever. Its fire assessments cover Firecore and E-Core doors, and it uses a 60/70mm tubular latch rather than a mortice. See the Hamilton in Chapter 05 and the McGrath range.
