The Carbine CEL-3IN1 Digital Lever Lock (CEL-3IN1-SL8-SNKIT) is a three-credential digital lever lock providing touchscreen PIN code, RFID/NFC access, and mechanical key override. It fits into a standard 54mm lockset hole with no additional drilling, suits door thicknesses of 35-51mm, and includes a 60-70mm adjustable tubular latch. This kit includes 4 x AA Duracell Procell batteries.
The lock accepts PIN codes (4-8 digits), RFID cards, FOBs, wristbands, and most Mifare 13.56MHz NFC-enabled smartphones. Up to 25 user codes and 25 RFID credentials are stored locally in the lock - no hub, gateway, or internet connection required for any access function. A guiding code feature allows false digits to be entered before the real PIN to prevent shoulder surfing. Double authorisation mode (card plus code simultaneously) is also supported.
The CEL-3IN1 leverset is fire rated on E-Core and Pyropanel Maxi Pandor door assemblies (both at FRL -/60/30) and is fitted with an NCC-compliant SL8-style lever. A Matte Black variant (CEL-3IN1-SL8MBKIT) is also available. For an upgraded model with 100-credential capacity and Firecore fire certification, see the Carbine CEL2-3IN1-SL8SNKIT.
Usually ships same day if ordered before 11am AEST (excludes weekends and Queensland public holidays).
The CEL-3IN1-SL8 leverset is certified for use on two door core types, both at FRL -/60/30 (60 minutes integrity, 30 minutes insulation):
- E-Core doorsets - Jensen Hughes Report FAS220275 (formerly Warringtonfire), valid to 30/11/2027
- Pyropanel Maxi Pandor doorsets - Warringtonfire Report FRT220272, valid to 28/09/2028, covering nominally 48mm single and double leaf Pandor doorsets
Both assessments cover the leverset fitted with its tubular latch at a 70mm backset in the doorset configurations tested - fitting it outside that configuration puts the installation outside the certificate.
Fire certification is door-core-specific - always confirm your exact door core type before specifying. The deadbolt variant is not fire rated. See: Fire door types & certification · Fire rating certificates · Buyers Guide Ch05: Fire Door Smart Locks
Available Finish Options
Finish selection does not affect functionality, compliance, or performance.
Key Features
- Three access methods: touchscreen PIN code, RFID/NFC credential, and mechanical key override - all validated locally with no internet required. See: Buyers Guide Ch03: RFID access explained · PIN access explained
- Stores 1 programming code, up to 25 user PIN codes, and up to 25 RFID credentials.
- Works with RFID cards, FOBs, wristbands, stickers, and most Mifare 13.56MHz NFC-enabled smartphones.
- Guiding code support - enter additional false digits before your real PIN to prevent code identification from wear patterns or shoulder surfing.
- Double authorisation mode requires card and PIN code simultaneously for higher-security applications.
- PIN codes from 4 to 8 digits; 4 additional single-use access codes (4 digits each).
- Vacation mode disables all user credentials without deleting them.
- Passage mode holds the latch retracted (hold SET for 1 second).
- Auto-lock timer configurable from 5 to 99 seconds (default: off).
- Fire rated on E-Core and Pyropanel Maxi Pandor fire door assemblies to AS1530.4:2014 - FRL -/60/30 on both core types (leverset only, not deadbolt).
- IP54 rated - suitable for sheltered outdoor positions with occasional water splash; not suitable for fully exposed or rain-facing positions.
- NCC-compliant SL8-style lever.
- Fits standard 54mm lockset hole with no additional drilling required.
- Suits door thicknesses of 35-51mm; backset 60-70mm adjustable.
- C4 keyway, 6-pin PD-style cylinder, supplied keyed to a 5-pin key - see how key override works.
- Low battery warning with visual and audible indicators before full depletion - see battery questions answered.
- Volume control for keypad sounds (on/off).
- Touchscreen locks out after four incorrect code entries, so the keypad cannot be worked through combination by combination; RFID credentials and the mechanical key still work while the keypad is disabled.
- Factory reset returns the programming code to its 12345678 default and clears stored user credentials, so every code and card is re-enrolled afterwards.

The CEL-3IN1 operates on 13.56MHz Mifare NFC. It is compatible with RFID cards, FOBs, wristbands, and stickers. Most NFC-enabled Android phones with Mifare support will also work, however compatibility varies by phone manufacturer and model. We strongly recommend testing your specific phone before installation. If your phone is not compatible, Mifare RFID stickers are available to adhere to the back of your device and function as a physical credential.
Any MIFARE credential to ISO14443 Type A at 13.56MHz will read, which includes many MIFARE cards a building already issues and Australian transport cards such as the Brisbane TransLink Go card (a MIFARE Classic 1K). Contactless bank cards do not work - payWave and PayPass use the EMV Type B standard, which this reader does not read. Carbine sets the full list out in the CEL RFID Application List (PDF).

Dimensions
Battery, Power & Backup Access
- Powered by 4 x AA alkaline batteries. Duracell Procell batteries are recommended - do not use lithium or rechargeable (NiMH) batteries.
- Battery life is approximately 5,000 openings. Actual life depends on usage frequency, ambient temperature, and battery brand. High-use properties (Airbnb, small business) will see faster battery turnover than low-traffic residential doors.
- Low battery warning is provided via LED and audible indicators before full depletion - typically with several days of continued use remaining.
- Mechanical key override provides physical backup entry at all times using the included C4 cylinder keys - always keep a key stored securely off-site.
- This KIT version includes batteries. Non-KIT variants (CEL-3IN1-SL8SN / CEL-3IN1-SL8MB) do not include batteries.
- Mechanical override aside, nothing on this lock depends on the internet, a hub or mains power - see smart versus connected locks.

Frequently Asked Questions
The CEL2 is the next generation of the CEL-3IN1. It uses the same physical footprint and fits the same 54mm hole, but includes an improved touchscreen and motor, a lower-profile escutcheon, and expanded credential capacity of 100 user codes or RFID connections (up from 25 on the CEL-3IN1). The CEL2-3IN1 leverset also carries Firecore certification allowing up to -/120/30 on TVC40 doorsets. Retrofit plates are available for replacing CEL-3IN1 installations with CEL2 without re-drilling the door. See: Carbine CEL & CDL Buyer's Guide - CEL-3IN1 models
The lock uses 13.56MHz Mifare NFC. Most modern Android phones with NFC enabled will work when held near the reader. iPhone compatibility is more limited due to iOS background NFC reading constraints depending on the iOS version. We strongly recommend testing your specific phone model before purchasing or installing. If your phone is not compatible, Mifare RFID stickers are available that adhere to the back of your device and function as a physical credential - this is the most reliable fallback solution. See: Buyers Guide Ch03: RFID access methods
Yes - the leverset variant is certified for use on E-Core fire door assemblies to AS1530.4:2014, FRL -/60/30 (Jensen Hughes Report FAS220275, valid to 30/11/2027). The deadbolt variant is not fire rated. A fire door is a certified system - the lock certification must match the specific core type of the door it is fitted to. This lock is certified for E-Core and Pyropanel Maxi Pandor doorsets; if your door is Firecore, confirm compatibility before specifying. If you live in a Gold Coast apartment, your entry door is most likely a fire door - see our guide: What locks are compliant on Gold Coast apartment fire doors? Professional installation is required on all fire door applications. See also: Fire door types and smart lock certification · Fire rating certificates · Buyers Guide Ch05: Fire door core types
No. The CEL-3IN1 is compatible with 60-70mm adjustable backset only. It cannot accommodate a 127mm latch. If your door currently has a 127mm latch, the latch will need to be changed to a 60 or 70mm unit before the CEL-3IN1 can be fitted. See: How to measure your lock backset - standard sizes and Buyers Guide Ch02: Backset for full guidance before ordering. Replacement latches are in tubular latches and bolts.
The manufacturer specifies 4 x AA Duracell Procell batteries, or equivalent good-quality alkaline batteries. Do not use lithium or rechargeable (NiMH) batteries - these can cause erratic operation or damage to the electronics. Battery life is approximately 5,000 openings, though this varies with usage frequency, ambient temperature, and battery brand. For a realistic lifespan guide in Australian conditions, see: How long do digital door locks last?
On a standard residential door: yes, provided the door prep allows a second hole without compromising the door. On a fire-rated door: no. Fire door standards (AS1905.1) permit only one locking penetration - a second deadbolt bores a 54mm hole which exceeds the maximum secondary penetration allowance, voids the fire door certification, and prevents the door from self-latching correctly. See: Secondary locks and the one-penetration principle on apartment fire doors · upgrading the primary lock instead
On a standard timber door where the existing 54mm hole and backset match, DIY installation is possible by following the included installation guide carefully. However, professional installation is required on fire-rated doors (legal requirement) and strongly recommended on aluminium-framed doors and security screen configurations where door prep, clearance, and spindle adjustment require trade experience. Terry's Locksmiths can supply and install this lock across the Gold Coast. See: Buyers Guide Ch12: Installation & Troubleshooting · book a free site survey
Additional Information
The guiding code feature allows random digits to be entered before or after the real PIN code. The lock ignores the extra digits and unlocks when the correct sequence is detected within the string. This prevents observers identifying the correct code through shoulder surfing, and masks wear patterns on frequently pressed keypad digits. The anti-peep PIN function is explained further in Buyers Guide Ch03: PIN access methods.
IP54 means the exterior escutcheon is tested for dust protection and water spray resistance from any direction. This is suitable for sheltered entry positions where the door is not directly facing rain - for example, a covered entry or undercover porch. IP54 is not suitable for fully exposed gate positions or any door facing directly into weather. For those applications, look for IP65 or IP66. Critically, IP ratings do not cover UV degradation, salt air corrosion, or sustained heat - all significant factors in coastal Queensland. Confirm suitability for your specific location before purchasing. Full IP rating guide: Australian smart lock standards - IP ratings table · corrosion grading · coastal environments on the Gold Coast
The CEL-3IN1 is well suited to short-stay rental properties. Issue a unique PIN code to each guest for their stay and delete it at checkout - no key handover, no lockbox, no re-keying. Up to 25 separate user codes can be active simultaneously, and four single-use codes delete themselves after one entry - useful for a one-off cleaner or tradie visit. For properties running back-to-back bookings via a property management system, the CEL2-BT-SL8SNKIT (Bluetooth-enabled Satin Nickel variant) adds app-based code management.

The CEL-3IN1 leverset is certified for E-Core fire door assemblies. When specifying for fire door use, confirm that all other hardware in the assembly - hinges, seals, closer - is also fire rated and compatible with the certified configuration. The fire certificate covers the lock in the same door configuration as tested; modifications outside that configuration may void compliance.
If the fire door is in a Gold Coast apartment building, be aware of three asbestos risk windows that may require a pre-drilling assessment before any locksmith works on the door: pre-1990 construction, Korab/Pyrokor recall (1993-1998), and a current active alert for Pyropanel FRB board imported 2021-May 2025 (chrysotile asbestos contamination confirmed by the Australian Border Force). Terry's Locksmiths will assess asbestos risk before commencing any fire door work. See: Asbestos in Gold Coast apartment fire doors - the three risk windows · Ch11: asbestos in door cores · body corporate approval
The three most common smart lock installation errors - wrong spindle position, mismatched backset, and door misalignment - all accelerate motor wear and reduce service life. A lock installed on a binding door is working harder on every operation cycle. If your door doesn't hang squarely and close smoothly without force, address that before fitting the lock. See: 3 common DIY smart lock installation mistakes and easy fixes and Buyers Guide Ch12: Installation & Troubleshooting. Terry's Locksmiths can supply and install across the Gold Coast, or recommend what fits your door.
The lock stores up to 25 RFID credentials and 25 user PIN codes as separate pools, plus 1 programming code and 4 single-use codes. The programming code is for lock configuration only and cannot be used as a regular access code. If 25 credentials are insufficient for your application, the CEL2-3IN1-SL8SNKIT increases this to 100 user codes or RFID connections. For a full explanation of how smart lock access methods and credential management work, see Buyers Guide Ch03: Access Methods comparison and Ch01: the authentication stack. Carbine states its capacities in the CEL-3IN1 user guide.

Carbine CEL-3IN1 Satin Nickel - FAQ, Setup and Owner's Guide
Everything buyers, installers and owners ask us about the CEL-3IN1 leverset, answered in one place. For questions that apply to any digital lock, see our Smart Lock FAQ (Chapter 13), or start at the Smart Lock Buyer's Guide. If you are still choosing, the Quick Start Guide walks through access methods, and Chapter 10 covers where Carbine sits against the other brands we stock.
Access, Credentials and Codes
Twenty-five user PIN codes and twenty-five RFID credentials, held as two separate pools, plus one programming code and four single-use codes. User codes are 4 to 8 digits; the single-use codes are 4 digits and delete themselves after one entry. The programming code (factory default 12345678) configures the lock and is not an everyday access code - change it before the lock goes into service. If twenty-five of each is not enough, the CEL2-3IN1-SL8SNKIT holds one hundred credentials in a single shared pool. Full capacity detail is in the CEL-3IN1 user guide, and Chapter 03 explains how code management works across platforms.
After four incorrect entries the touchscreen disables itself for a short period, so a passer-by cannot stand at the door and work through combinations. Your RFID credential and the mechanical key override still work while the keypad is locked out. This behaviour is documented in the user guide.
Any MIFARE credential running at 13.56MHz to ISO14443 Type A. That covers the Carbine range - the MIFARE card, key fob, ultra fob, adhesive sticker and silicone wristband - and many MIFARE cards a building already issues, including Australian transport cards such as the Brisbane TransLink Go card, which is a MIFARE Classic 1K. Contactless bank cards do not work: payWave and PayPass run on the EMV Type B standard, which this reader does not read. The full list is in the Carbine RFID Application List, and you can browse every credential we stock in RFID fobs, tags and cards.
Sometimes - and it is worth testing before you buy. The lock reads MIFARE at 13.56MHz, so an NFC-enabled Android phone that presents a MIFARE credential will usually work. iPhones are more limited, because iOS restricts background NFC card emulation. There is no app and no Bluetooth pairing involved here; the phone is simply acting as a card. If your phone will not read, the reliable fallback is a MIFARE sticker on the back of the case. If app control matters to you, step up to the CEL2-BT-SL8SNKIT instead. Background on credential types is in Chapter 03.
It lets you pad your PIN with extra digits. Enter random numbers before or after the real code and the lock still opens, because it looks for the correct sequence inside the string you typed. Two things follow from that: someone watching over your shoulder cannot tell which digits mattered, and your genuine digits do not wear a visible pattern into the keypad. It costs nothing to use and is the single best habit to adopt on a shared door. See Chapter 03 on PIN access.
It requires two credentials together - a card and a PIN - before the lock will open. On a normal residential door it is overkill. Where it earns its place is a store room, a dispensary, a records room or a cash office, anywhere one lost card should not be enough to get in on its own. It is switched on through the programming menu and can be turned off again at any time.
No. Delete that credential from the lock and it stops working - the other twenty-four are untouched and nothing is re-cut or re-pinned. That is the practical advantage of card and code access over keys alone in a rental or a strata building, and it is why we recommend issuing one credential per person rather than sharing. Losing a mechanical override key is a different matter, since the C4 cylinder would need to be rekeyed: keep the spare somewhere sensible, as covered in key storage for override keys.
Fire Doors and Compliance
Two core types, both at FRL -/60/30. E-Core doorsets are covered by Jensen Hughes assessment FAS220275 DHAR1.8, issued December 2025 and valid to 30 November 2027. Pyropanel Maxi Pandor doorsets are covered by Warringtonfire assessment FRT220272, valid to 28 September 2028, for nominally 48mm single and double leaf doorsets. Certification is core-specific: if your door is Firecore, this assessment does not cover it, and you want the CEL2 range instead. Chapter 05 on door core types explains why one certificate never covers another core, and Chapter 11 covers AS1905.1 and the NCC.
Yes, and this catches people out. Both assessments cover the leverset fitted with its tubular latch at a 70mm backset, in the doorset configurations that were tested. Fit the same lock outside that configuration - a different core, a different latch, hardware in the assembly that is not fire rated - and you are outside the certificate, whatever the lock itself is capable of. Confirm the hinges, seals and closer are compatible with the certified configuration as well. See how fire certification is established and where the test reports live.
Usually your apartment entry door is a fire door, which changes three things: the lock has to be certified for that door's core, the body corporate normally has to approve the change, and installation is a job for a locksmith rather than a weekend. It is also why a second deadbolt is out of the question - fire door rules allow one locking penetration, so boring a second 54mm hole voids the certification. Read what locks are actually compliant on Gold Coast apartment fire doors, the one-penetration principle, and the strata checklist in Chapter 05. Browse everything certified for these doors in fire door smart locks.
Because some fire door cores contain it. Three windows matter: buildings constructed before 1990, the Korab and Pyrokor recall between 1993 and 1998, and the current alert on Pyropanel FRB board imported between 2021 and May 2025, where the Australian Border Force confirmed chrysotile contamination. We assess the door before any cutting starts. The detail is in asbestos in Gold Coast apartment fire doors and Chapter 11.
Yes - it is an SL8-style lever, which meets the NCC requirement for a lever that can be operated without a tight grip or a twisting wrist action. That is the same reasoning behind accessible hardware generally, covered in Chapter 11 on security and compliance grading.
Will It Fit My Door?
Three numbers. The bore hole in the door face (this lock takes the standard 54mm), the door thickness (35 to 51mm), and the backset from the door edge to the centre of that hole (60 or 70mm, adjustable on the supplied latch). If your door already carries a bored cylindrical lockset at 54mm, the CEL-3IN1 goes straight in with no new holes. How to measure your backset takes two minutes, and Chapter 02 shows what bored cylindrical prep looks like.
Not as it stands. The CEL-3IN1 covers 60 to 70mm only. A 127mm backset means the existing latch has to come out and be replaced with a 60 or 70mm unit, which is straightforward on most doors but does need to happen before the lock goes on. Getting this wrong is one of the most common ordering mistakes we see - see what happens with the wrong backset and Chapter 12. Replacement latches are in tubular latches and bolts.
For this leverset, handing is handled at installation rather than at order time - the installation sheet covers setting the handle direction and the optional lever swap. It is still worth knowing your handing before a locksmith arrives, particularly if other hardware is being changed at the same time. How to determine handing in Australia explains the LHI, RHI, LHO and RHO convention.
Often yes - we have fitted plenty on aluminium pedestrian gates, and the installation gallery on this listing shows several. Two checks first: the frame has to be thick enough to land in the 35 to 51mm range, and there has to be clearance between the escutcheon and any screen or security door in front of it. The exterior module projects 28mm from the door face. Chapter 02 on screen clearance covers the measurement, and Chapter 04 has the full door-type matrix. Note that a fully exposed gate facing weather is better served by a higher IP rating than IP54.
Power and Backup Access
Four AA 1.5V alkaline cells - Duracell Procell, or an equivalent quality alkaline. Do not fit lithium or rechargeable NiMH cells: the voltage behaviour is wrong for this board and the usual result is erratic operation. Expect roughly 5,000 openings, which is a long time on a house door and considerably less on a busy short-stay or small-business door. The kit on this listing ships with the batteries included. The realities of electronic door locks is honest about what shortens battery life, and Chapter 13 answers the general battery questions.
You use the key. The lock carries a C4 keyway cylinder with a 6-pin PD-style body, supplied keyed to a 5-pin key, and two keys come in the box - that is the whole point of a key override. The lock warns you first, with a visual and audible low-battery indication that typically gives you several days of normal use. Keep one override key somewhere you can actually reach it, which is not inside the locked building. See what happens when the battery dies and where the override keyhole sits. Every lock we stock with a key cylinder is listed under has backup key.
No. There is no app, no hub, no gateway and no WiFi anywhere in this product - every code and card is validated inside the lock itself, on battery power. A blackout, a dropped NBN service or a dead router changes nothing at the door. The trade-off is that you cannot let someone in remotely or see who came and went; if you need that, you are looking at an app-connected lock such as the CEL2-BT-SL8SNKIT rather than this one. Chapter 01 on smart versus connected draws the line clearly.
Everyday Use and Settings
Yes - the auto-lock timer can be set anywhere from 5 to 99 seconds, so the latch re-secures on its own after the door closes. Set it short on a front door and longer on a door people prop while carrying things in.
Hold SET for one second and passage mode holds the latch retracted, so the door opens on the handle with no credential. It is what you want for an open day, a clinic waiting room, a function, or a trade delivering all afternoon. Take it out of passage mode the same way when you are done.
That is exactly what vacation mode does. It suspends every user credential while leaving them programmed, so nothing has to be re-enrolled when you get back. The programming code and the mechanical key still work.
Yes, volume is an on or off setting in the programming menu. Worth turning off on a bedroom or apartment door where someone is asleep on the other side of the wall.
There are four of them. The single-use codes are 4 digits, and each one deletes itself the moment it has been used - ideal for a one-off delivery, a cleaner or a real estate inspection where you would rather not hand out a standing code. For repeat visitors, give them one of the twenty-five user codes and delete it when the arrangement ends. Chapter 13 covers day-to-day code management.
Short-Stay, Rental and Commercial Use
For getting guests through the door, yes. Issue a code for the stay, delete it at checkout, and nobody hands over a key or maintains a lockbox. What an offline lock cannot do is generate codes automatically from your booking calendar or let you check the door from another suburb - that needs a connected platform. Most single-property hosts on the Gold Coast do fine with a keypad lock and a cleaning routine. Do you really need WiFi for an Airbnb lock? works through the honest version, and Chapter 07 compares the two approaches.
For a team of up to about twenty with a few contractor credentials, comfortably. Past that - or where several doors need the same credential set - the CEL2-3IN1 at one hundred credentials is the better fit, and it shares this lock's 54mm bore so the door prep carries over. Do remember there is no audit trail on an offline lock: it tells you nothing about who opened the door and when.
Weather, Coastal Exposure and Service Life
IP54 describes the exterior escutcheon: dust protected, and splash resistant from any direction. A covered entry, a porch, a breezeway - fine. A door or gate that takes driving rain on the face - no, and that is where we would steer you to an IP65 or IP66 product. The interior module houses the battery compartment and is an inside-only part regardless. The IP rating table in Chapter 11 sets out what each figure means.
Salt air is harder on hardware than rain is, and an IP figure says nothing about it - IP testing covers dust and water, not corrosion. Carbine does publish how it salt spray tests its locksets, to AS4145.2-2008, and that document is in the PDF downloads on this page, but it is written for the lockset range generally rather than quoted against this model, so we are not going to put a number against this SKU. What we tell coastal customers is practical: rinse the escutcheon with fresh water occasionally, expect the finish to age faster within a few hundred metres of the surf, and take the exposure into account when you choose between finishes. Chapter 11 on corrosion grading and coastal environments are both worth reading first.
It is an ANSI Grade 2 lockset, which puts it in the residential-to-light-commercial band rather than the high-traffic commercial one. In practice the biggest variable is not the lock: a door that binds, drops or needs a shoulder makes the motor work harder on every single cycle, and that is what shortens service life. Hang the door properly and it will outlive a well-used lock on a poorly hung one. How long do digital door locks last gives realistic figures, and cycle ratings explains the grading.
Installation, Servicing and Troubleshooting
On a timber door that already has a 54mm bore at the right backset, and no fire rating - yes, working carefully through the installation sheet. Get a locksmith for a fire door (that is not optional), an aluminium frame, or anything involving a security screen and tight clearances. Chapter 12 on when to DIY is a fair test. Terry's Locksmiths supply and install across the Gold Coast - supply and install, or a free site survey if you have several doors.

Three of them, every time: the spindle in the wrong position, a latch at the wrong backset, and a door that is out of alignment so the latch has to be forced into the strike. All three feel like a faulty lock and none of them are. The cable is the fourth - it has to be routed so the door edge does not pinch it. The three common DIY mistakes and the Chapter 12 symptom table cover the fixes.
Batteries, then the cable. Fit four fresh AA alkalines (not lithium, not rechargeable) and try again; if the screen is still dead, the internal cable between the two modules is the next suspect, and a pinched or unseated cable is common after a DIY fit. Carbine's troubleshooting guide works through this and the other usual faults, and the FAQ card shows battery, spindle and cable fitting right and wrong in pictures.
Not recovered, but reset. A factory reset returns the programming code to 12345678 and clears the user credentials, so every code and card has to be enrolled again afterwards. The procedure is in the user guide. Set a new programming code immediately - a lock left on the factory default is not secured.
Carbine publishes a ten-step cable replacement instruction for the CEL series leverset, so the job is documented - but read the warranty note in it first. Carbine states that once the original label is torn off to carry out the replacement, the lockset is no longer under warranty. If the lock is still inside its 12-month electronic warranty period, talk to us before opening it up rather than after.
Choosing Between the Carbine Models
Same 54mm bore, same backset range, same three credential types. The CEL2 brings a newer touchscreen and motor, a lower-profile escutcheon, one hundred credentials instead of twenty-five plus twenty-five, and Firecore certification reaching -/120/30 on TVC40 doorsets. Retrofit plates exist for covering the older screw positions when a CEL-3IN1 is swapped for a CEL2, so you are not re-drilling the door. Buy the CEL-3IN1 when twenty-five codes is plenty and your fire door is E-Core or Pyropanel; buy the CEL2-3IN1-SL8SNKIT (or Matte Black) for capacity or a Firecore door. The range comparison table puts every model side by side.
Phone-based management. The CEL2-BT-SL8SNKIT adds the Carbine Connect app, so codes are issued and revoked from your phone instead of at the keypad. Be clear about the limit: Carbine Connect is Bluetooth only, with no gateway or cloud, so you still have to be at the door - it is not remote access. Chapter 03 on remote access explains what a gateway actually buys you.
The CDL2 leverset costs less and covers PIN and key. What you give up is real: no RFID at all, a membrane keypad rather than a touchscreen, twenty codes instead of twenty-five plus cards, and no fire rating. If cards, fobs or a fire door are part of the brief, the CDL2 is not the lock. There is also a CDL2 deadbolt for secondary-lock duty.
A leverset like this one replaces the lock you already operate - one hole, one set of hardware, and the door latches on closing. A deadbolt is a second, separate lock above the handle and it does not latch on its own. On a fire door the choice is made for you: one penetration, so the leverset is the upgrade. Elsewhere a deadbolt suits a door whose existing handle set is staying. The RFID deadbolts are the CEL2-3IN1-DBSNKIT and DBMBKIT, and Chapter 01 explains latch versus bolt formats. See also upgrading the primary lock instead of adding a second one.
In the CEL2 range the FR kits are packaged and documented specifically for certified fire door installation, with the fire assessment supplied alongside. The CEL-3IN1 on this page is not sold as an FR kit, but the leverset itself is assessed for E-Core and Pyropanel Maxi Pandor doorsets, which is what the certificate in the PDF downloads shows. If you want the dedicated fire door kit, the options are CEL2-3IN1-SL8SN-FRKIT, SL8MB-FRKIT, or the Bluetooth versions CEL2-BT-SL8SN-FRKIT and SL8MB-FRKIT.
