The Carbine CEL2-3IN1-DBMBKIT is the deadbolt variant of the CEL2-3IN1 range, providing touchscreen PIN code, RFID/NFC access, and mechanical key override in a compact escutcheon format. It stores up to 100 user codes or RFID credentials in a shared pool, with no hub, gateway, or internet connection required.
The deadbolt is suited to secondary security on doors that already have a primary latch lock - such as an entry door with a tubular latch leverset. The deadbolt bolt throw provides a solid independent locking point separate from the latch. See: What is bolt throw and why does it matter? and Secondary locks and the one-penetration principle.
Important: This deadbolt model is not fire rated. For fire door applications, use the CEL2-3IN1 fire-rated leverset models (CEL2-3IN1-SL8MB-FRKIT in Matte Black, CEL2-3IN1-SL8SN-FRKIT in Satin Nickel). A Satin Nickel variant (CEL2-3IN1-DBSNKIT) is also available. For the leverset version, see the CEL2-3IN1-SL8SNKIT. For Bluetooth deadbolt access, see the CEL2-BT-DBSNKIT (note: that model does not include RFID).

Frequently Asked Questions
No. The CEL2-3IN1 deadbolt does not carry fire door certification. It is not suitable for installation on fire-rated door assemblies. For fire door applications, refer to the CEL2-3IN1 fire-rated leverset models in the product family table above - CEL2-3IN1-SL8MB-FRKIT (Matte Black) and CEL2-3IN1-SL8SN-FRKIT (Satin Nickel). See also: Secondary locks and fire-rated doors, Buyers Guide Ch05: Fire Door Smart Locks and all fire door smart locks.
Most NFC-enabled Android phones with Mifare support work. Test your specific device before installation. If incompatible, adhere a Mifare RFID sticker to the back of your phone as a workaround. Visa PayWave and Mastercard PayPass are not compatible. See: Carbine CEL RFID Application List (PDF) and Buyers Guide Ch03: RFID access methods.
Yes. The CEL2-3IN1 deadbolt includes an adapter collar that enables installation into a 38mm bore hole. Remove the screw post and adapter collar before installation as shown in the installation instructions. See: Buyers Guide Ch02: Door preparation.
The CEL2 escutcheon is a new lower-profile design and screw hole positions may not align with the original CEL. Retrofit plates (CEL2-DB-RP-SS or CEL2-DB-RP-MB) are available to cover old screw holes on the external face. The spec sheet for retrofit plates is available as a PDF download below, and the wider range sits under scar and adaptor plates.
After 4 consecutive incorrect entries, the lock temporarily disables the keypad. If you forget the programming code, a factory reset is required - this erases all stored codes and resets the programming code to the factory default (12345678). See the troubleshooting guide for the factory reset procedure. See: Buyers Guide Ch12: Installation & Troubleshooting.
Additional Information
Unlike the leverset models, the CEL2-3IN1 deadbolt automatically detects its handing (which direction the bolt throws) after a factory reset. This process requires the lock to be fully installed on the door before performing the reset. Do not test handing off-door. If the bolt direction appears reversed after installation, perform a factory reset with the lock on the door and allow it to complete its self-calibration cycle - the troubleshooting guide puts that cycle at about 30 seconds.
The connecting cable between the exterior and interior modules must be routed correctly into the designated channel in the mounting plate. Incorrect routing is the most common installation issue - a pinched or misrouted cable can cause the keypad to be unresponsive, the battery cover to not fit correctly, or the Set button to be held down unintentionally. If the keypad stops responding after the battery cover is installed, the cable is almost certainly pinched. See the troubleshooting guide PDF for correct and incorrect cable routing photographs. See also: 3 common DIY smart lock installation mistakes and Buyers Guide Ch12: Installation mistakes.
Auto-lock is off by default on this deadbolt model. When enabled, the bolt will extend automatically after 10-99 seconds (you set the delay via the programming sequence). This is different to the leverset models, which have a 5-99 second range. If you rely on auto-locking, always test it after programming to confirm it is operating correctly.
The factory default programming code is 12345678. This code can unlock the lock as well as access programming mode. Change it to a private code immediately after installation. Do not share the programming code with tenants or regular users - create separate user codes for day-to-day access. See: The realities of electronic door locks and Buyers Guide Ch07: setup checklist.
A deadbolt does not include a latch - it cannot hold a door closed passively. It must be used alongside a separate latch mechanism (such as a leverset) for the door to function correctly. Confirm the door already has a working primary latch before specifying a deadbolt-only installation. See: Deadbolts vs deadlatches - the one-penetration principle and Buyers Guide Ch01: what a deadbolt is.

Carbine CEL2-3IN1 Deadbolt - FAQ, Setup and Owner's Guide
The questions below are the ones we get asked most often about the CEL2-3IN1 deadbolt, answered from Carbine's own installation, programming and troubleshooting documents. For the wider picture, see the Smart Lock FAQ (Buyer's Guide Chapter 13) and the Smart Lock Buyer's Guide.
Fit, Door Preparation and What You Need
A timber or equivalent door 35mm to 51mm thick, with a 54mm bore hole (or 38mm using the supplied adapter collar), a 25mm edge hole for the bolt, and a backset of either 60mm or 70mm. Carbine's drilling template marks the four door thicknesses it is set up for - 35, 40, 45 and 51mm. Measure all three figures before you order: how to measure your backset, then Buyer's Guide Ch02 on door thickness.
No. The adjustable latch covers 60mm and 70mm only - a 127mm backset is outside its range. If your existing hole is at 127mm you are looking at a different product or a new door preparation. See Buyer's Guide Ch02: Backset, and the CEL / CEL2 / CDL2 family table for the alternatives we stock.
Yes. The kit includes a reinforced strike plate, and Carbine's installation sheet specifies 76mm (3in) screws to fix it - long enough to reach past the jamb into the stud behind it. The rest of the hardware is 52mm (2in) mounting bolts plus 32mm and 19mm screws. Long strike screws are the single cheapest security upgrade on any deadbolt installation, so use the ones supplied rather than the short screws already in the door. Full parts list: Installation Instructions (PDF).
No - and this is the most important thing to understand before ordering. A deadbolt has no latch, so it cannot hold the door closed on its own. It needs a working primary latch (a leverset, knobset or deadlatch) alongside it. If you want one lock that does both jobs, choose a CEL2-3IN1 leverset instead: CEL2-3IN1-SL8MBKIT in Matte Black or CEL2-3IN1-SL8SNKIT in Satin Nickel. Background: deadbolts vs deadlatches and Buyer's Guide Ch01: the deadbolt explained.
The bore and backset are the same, so you will not be drilling a new hole, but the CEL2 escutcheon is a new lower-profile shape and the fixing screw positions do not always match the old one. Carbine makes a retrofit plate for exactly this: 75 x 147mm, 1.6mm thick, with a 55mm cut-out, in 304 stainless steel - natural brushed (CEL2-DB-RP-SS) or satin black to match this lock. See the retrofit plate spec sheet (PDF), the accessories table, or browse scar and adaptor plates.
It can. The exterior module stands proud of the door face, and a screen door hung close to the main door will hit it. Measure the clearance between the two before you buy - it is a five-minute check that saves a return. See check screen door clearance before fitting a smart lock.
Access, Codes and Credentials
Up to 100 - but that is a shared pool, not 100 codes plus 100 cards. Every PIN code and every RFID credential you add comes out of the same 100. In practice that is far more than a household or a small office will ever use, and it is four times the capacity of the original CEL-3IN1 generation. On top of the 100 you also get 4 sets of single-use codes. Compare the range in the family table or the Carbine CEL & CDL Buyer's Guide.
Four to eight digits, and you set the length per code. The programming code is always eight digits. A code cannot be a subset of another stored code, so plan your numbering before you start adding users rather than working around rejections later. See Programming Instructions (PDF).
A guiding code lets you type random digits either side of your real code before pressing the confirm key, so anyone watching cannot tell which digits matter. It does not weaken the code - the lock simply searches the string you entered for a valid code. It is the single most useful feature on a lock fitted to a front door that faces a street or a shared landing. See Buyer's Guide Ch03: PIN access.
Yes. The lock holds up to four sets of single-use codes, four digits each. The code works once and then expires, which suits a one-off delivery, a cleaner between guests or a tradesperson attending while you are out. For anything more elaborate - dated windows, recurring schedules - you need a lock with an app; see Buyer's Guide Ch07 on short-stay code strategies.
Any 13.56MHz MIFARE credential on ISO14443 Type A. Carbine's own range is the safe choice and all five formats are stocked: the CEL-RFID card (86 x 54 x 0.8mm, NXP Mifare S50), the CEL-RFID-ST-C sticker (25mm metal label), the CEL-RFID-FOB keyring fob, the more compact CEL-RFID-UFOB, and the IP68 CEL-RFID-WB wristband. Full list: Carbine CEL RFID Application List (PDF) · browse RFID fobs, tags and cards.
Usually yes, because Australia's transit cards are MIFARE. Carbine's application list names Brisbane's Go card, Sydney's Opal, Melbourne's Myki, Perth's SmartRider, Canberra's MyWay, Adelaide's metroCard and Hobart's Metro Green Card. What will not work is a payment card - Visa payWave and Mastercard PayPass are ISO14443 Type B and the lock cannot read them. Register the transit card the same way you would register a Carbine card. See Buyer's Guide Ch03: RFID access.
Most NFC Android handsets that emulate MIFARE will, and Carbine lists Classic, S50 1K, S70 4K, Ultralight, Plus S/X and DESFire EV1 among the systems the reader accepts. Phone behaviour varies by handset and by Android version, so test before you commit. If your phone will not play, the fix is a MIFARE sticker on the back of the case - it presents exactly like a card. Keep it clear of the wireless charging coil.
They may work, but Carbine only guarantees its own cards, and there is a real failure mode worth knowing: if a third-party card's settings are changed in another reader or writer, it can stop the lock reading it, and in some cases disturb the lock's stored credential. Davcor's support covers Carbine locks and original Carbine cards. For a handful of extra users the saving is not worth the callout - see the genuine credential range.
The lock ships with a C4 keyway cylinder, 6-pin PD style, keyed to a 5-pin key, and Carbine states it is rekeyable. Whether it can be keyed alike to your existing locks depends on what those locks are - bring a key in and we will tell you in a minute. See smart locks with a backup key.
Double authorisation makes the lock demand both a valid card and a valid code before it will open, instead of either one on its own. It is a two-factor setting for a door that genuinely warrants it - a dispensary, a records room, a store room in a shared building. For an ordinary front door it usually gets turned off within a week because it doubles the effort every entry.
Programming, Setup and Resets
It is 12345678, and yes - change it before anyone else uses the door. That code does two jobs: it opens the lock and it opens programming mode, so anyone who knows it can add their own credential. Note it is eight digits, not the six used on the CDL2 range - do not follow a CDL2 sequence on this lock. Give day-to-day users their own user codes and keep the programming code to yourself. See the realities of electronic door locks.
Take one battery out, hold the SET button, and refit the battery while still holding it. That restores the programming code to 12345678 and erases every stored user code and card - and it also erases the lock's stored bolt direction, which is why the reset must be done with the lock installed on the door. Step-by-step: Programming Instructions (PDF) and Troubleshooting Guide (PDF).
No - it works that out for itself, but only once it is on the door. The lock sets its bolt direction during the self-calibration that follows a factory reset, and the troubleshooting guide puts that cycle at about 30 seconds. The trap is connecting the cable and powering the lock up on the bench first: it will hand itself to the bench, not to your door, and the bolt will then run backwards. If that has already happened, refit it and reset it. See Additional Information.
Because auto-lock ships switched off. Turn it on through the programming sequence and set a delay anywhere from 10 to 99 seconds; the default once enabled is 10 seconds. The leverset models run 5 to 99 seconds, so do not go by a figure you have read on a leverset page. Whatever you set, stand at the door and watch it lock once before you rely on it.
Yes - volume is a simple on/off setting in programming. Worth turning off on a bedroom-adjacent door or where the entry is used late at night; worth leaving on where you want the audible confirmation that a code registered.
It suspends every user code and card in one step, leaving the programming code and the mechanical key working. It is the right setting for a property standing empty - an investment unit between tenancies, a holiday house over winter - because you are not deleting anyone, just switching them off until you come back.
Green is a correct entry, red is an incorrect entry or programming mode, and yellow is the low battery warning. If you are seeing yellow on every entry, change all four batteries as a set rather than topping up the weakest one.
Power and Batteries
Four AA 1.5V alkaline, and no to both. Carbine is explicit in its own troubleshooting guide: alkaline only, Procell or Duracell recommended, no lithium and no rechargeable cells. Lithium AAs sit at a higher voltage and rechargeables at a lower one, and the lock's motor and low-battery sensing are calibrated for 1.5V alkaline. The KIT you are buying includes a set of Duracell Procell.
Around 5,000 openings. On a typical household front door that is a change roughly once a year; on a busy office or short-stay door it will be sooner. The lock warns you first with a yellow indicator and a tone, so you should never be caught out - and if you are, the mechanical key still works. See how long do digital door locks last?
No, and it is worth acting on. Carbine's troubleshooting guide traces a hot battery compartment to a pinched or shorted connecting cable, not to the batteries themselves. Take the cover off, remove the batteries, and check the cable is sitting in its channel and has not been trapped under the mounting plate. See the Troubleshooting Guide (PDF).
Installation and Troubleshooting
That is the cable, nine times out of ten. The connecting cable has to run in the channel cut into the mounting plate; if it sits proud it gets squashed by the interior housing or holds the SET button down, and the lock stops responding. The same fault shows up as a battery cover that will not sit flush. Pull the cover, re-route the cable under the tabs, and try again. Photographs of right and wrong routing: Troubleshooting Guide (PDF). See also 3 common DIY installation mistakes.
Look at the strike before you look at the lock. A strike hole that is too shallow or slightly out of alignment stops the bolt completing its travel, and the motor labours against it. Deepen or realign the strike, then run a factory reset with the lock fitted so the bolt motor re-learns its end points. A stiff key or thumbturn points the same way. See Buyer's Guide Ch12: misalignment.
That is the lockout working as intended - four consecutive wrong entries and the screen disables itself for a short period. Wait it out, or use the mechanical key. If you have lost the programming code as well, a factory reset is the only way back in, and it clears every stored user. See Buyer's Guide Ch12: Troubleshooting.
If the door is already bored at 54mm on a 60 or 70mm backset, it is a straightforward swap with a screwdriver and the supplied template - the two things to get right are the cable routing and doing the reset on the door. If you are cutting a new bore, working on an apartment entry door, or the door is out of alignment to start with, get a locksmith on it. We install on the Gold Coast: Advice and Installation.
Suitability, Compliance and Choosing Between Models
No. Carbine's fire certification covers the CEL2 leverset variants only - the brochure states the 2-hour rating for the leverset, and there is no fire test behind the deadbolt. On a fire-rated door assembly you need a certified leverset: CEL2-3IN1-SL8MB-FRKIT or CEL2-3IN1-SL8SN-FRKIT. If you are not sure whether your door is fire rated, Buyer's Guide Ch05 shows you how to tell; the whole certified range is under fire door smart locks.
The exterior module is IP54, which covers dust and splashing water - rain blown onto a door under an eave or a recessed entry. It is not a gate lock and it is not built for a face that takes driving rain and full sun all day. For what the IP figures actually mean, see Buyer's Guide Ch11: IP ratings; for a sheltered front door this is the right class of product - browse regular front door smart locks.
It is a durability and strength classification: Grade 1 is commercial heavy duty, Grade 2 sits above ordinary residential, Grade 3 is light residential. Grade 2 on a domestic entry door is more than the door will ever ask of it. Note the deadbolt carries no NCC lever compliance figure - that standard applies to lever designs and a deadbolt has no lever. See Buyer's Guide Ch11 on lock standards.
No on both counts, by design. This is a standalone lock - no Bluetooth, no gateway, no internet, nothing to log into and nothing to drop off your network. If you want app control on a Carbine deadbolt, the CEL2-BT-DBMBKIT adds Bluetooth and the Carbine Connect app - but note it drops RFID entirely, and Carbine Connect works in Bluetooth range only, so it will not open the door from your office either. Read how the platform works: Carbine Connect Platform Guide · Buyer's Guide Ch15: App Platforms.
RFID and capacity. The CDL2 deadbolt is PIN and key only, on a membrane keypad, with 10 user codes. This lock adds cards, fobs, stickers, wristbands and NFC phones, a touchscreen, and 100 credentials in the pool. If nobody in the household wants to carry a card and ten codes is plenty, the CDL2 will do the job for less. See the family table and the Carbine CEL & CDL Buyer's Guide.
For a second lock on the entry door, yes - guests get a code instead of a key, the code changes between stays, and there is no WiFi to drop out at 11pm. What it will not do is issue a code remotely or tell you who came and went, so if you manage the property from a distance or run several, look at an app-connected lock. See Airbnb smart locks - do you really need WiFi? and Buyer's Guide Ch07.
12 months. Carbine's warranty is tiered by product category and electronic and digital locks sit at 12 months, covering defects in materials and workmanship, replacement of product only. Batteries, finish damage and installation-related damage are excluded, and you will need proof of purchase. Full terms in the Warranty section.

- Contact Terry's Tradies Pty Ltd (the place of purchase) in writing as soon as the defect becomes apparent - and no later than 14 days after the end of the applicable warranty period.
- Include in your written claim: a description of the defect, the date of supply, your contact details, and satisfactory proof of purchase.
- Do not return the product until a return authorisation number has been issued by Davcor. If return is required, the product must be in its original, complete, and saleable packaging.
- Davcor will test and assess the product. No claim is valid unless Davcor has confirmed a defect is present.
- Once a valid claim is confirmed, Davcor will - at its discretion - repair the defect, replace the product, or supply an equivalent product. If repair or replacement cannot be completed within a reasonable time, you may request a full refund, provided the product has been returned.
Delivery inspection: If you believe a product is defective or incorrectly supplied at the time of delivery, telephone notice must be given within 72 hours of receipt, with written notice (including full particulars) within 14 days of the invoice date.
Exclusions
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 to compensation for any other reasonably foreseeable loss or damage. You are also entitled to have the goods repaired or replaced if they fail to be of acceptable quality and the failure does not amount to a major failure. The Carbine/Davcor express warranty operates alongside and in addition to your rights under the Australian Consumer Law.
