Borg BL2002SC Mechanical Digital Lock - Knob Keypad - 28mm Mortice Latch - Satin Chrome
At A Glance
The Borg BL2002SC is a fully mechanical digital lock built for narrow stile doors and gates, using a 28mm backset mortice latch with a compact 96×26mm faceplate. It is the no-holdback version of the BL2202SC - the inside paddle handle operates freely at all times without a holdback mechanism. The correct choice where a compact 28mm latch is needed but the holdback function is not required.
Satin chrome finish. On-the-bench code change (lock removed for coding - see how it works). Over 8,000 combinations. Single-sided - the inside handle is always free for immediate egress. Suits doors from 35mm to 54mm thick. No batteries.
Usually same day if ordered before 11am AEST (excluding weekends and Qld public holidays)
The BL2002SC uses a 28mm backset mortice latch with a 96×26mm faceplate - designed for aluminium-framed doors and gates, narrow stile timber doors, and any application where a standard 60mm backset latch is too deep for the stile. Not sure whether your frame counts as narrow? Our guide to measuring your gate or door stile walks through the two size groups and what to check before you order. If your stile is wide enough for a 60mm latch, consider the BL2200 (on-the-bench, holdback, 60mm) or BL2501SSECP (ECP, satin stainless, 60mm).
The inside paddle handle is always free to operate. No code is required to open the door or gate from inside.
The 28mm mortice latch format is compatible with electric strikes, making the BL2002SC a genuine option for access-control integrations where an electric strike releases the latch on command. Confirm the exact strike model with your access control supplier before specifying.
The BL2002SC has a simple paddle handle inside with no holdback mechanism. The latch returns to the latched position automatically when the door or gate closes. If a holdback function is required, see the BL2202SC - same 28mm latch, same keypad, with holdback added.
This model's code change happens on the bench with the lock off the door - not through the keypad on the door face. It's a fiddly job with the cover plate off and the supplied tweezers in hand; see the full step-by-step below. If you think you'll want to change the code more than once a year, take a look at Borg's Easicode Pro (ECP) range instead - the code changes from the keypad itself in under a minute, no lock removal required.
Entirely mechanical. No power source, no wiring, and no battery maintenance at any point.
For heavy duty: consider the Borg BL7701, Lockwood DX, or Carbine CDL7000.
Accepts one active PIN code at a time.

How to Change the Code - On The Bench
This model's code is changed with the lock removed from the door - there's no on-door keypad procedure. It's a fiddly job, best done with good light and a steady hand. Our Borg standard-chamber code change guide covers the same procedure with photos if you'd like to see it before you start:
- Remove the lock from the door and take out the 4 red screws.
- Carefully lift the cover plate - the springs stay attached, so lift slowly.
- Hold the C-pin depressed the whole time you're working.
- Use the supplied tweezers to reposition the red (coded) and blue (uncoded) pins - square cut-outs face outward, coloured marks face upward.
- Test the new code before reinstalling the lock on the door.
Codes are non-sequential, so buttons can be pressed in any order. Spare pins let you adjust the code length from 3 to 7 digits. Most people manage the swap in around 20-30 minutes the first time; it gets faster with practice, and a locksmith will be quicker still.
Expect to change the code more than once a year? Borg's Easicode Pro (ECP) range changes the code from the keypad itself in under a minute, with the lock still on the door - no removal, no fiddly pins, no tweezers. For a narrow-stile 28mm option with ECP, see the BL2702SCECP (adds a key override too); for 60mm-backset ECP options see the BL2201SCECP or BL2501SSECP.
Frequently Asked Questions
Both use the same 28mm backset mortice latch for narrow stile doors and gates and are otherwise identical in mechanism and finish. The key difference: the BL2202SC has a holdback facility on the inside paddle; the BL2002SC does not. Choose BL2002SC where holdback is not needed and a simpler inside paddle is preferred; choose BL2202SC where you need to hold the latch open for free passage.
Many narrow stile doors and gates don't have a wide enough frame to mortice a standard 60mm backset latch. The BL2002SC's 28mm mortice latch has a compact 96×26mm faceplate designed to fit these narrow profiles. If your stile is wide enough to accept a 60mm latch, the BL2200 (60mm, holdback) or BL2501SSECP (60mm, ECP, satin stainless) may be more appropriate.
Yes. The 28mm mortice latch format is compatible with electric strikes, making the BL2002SC suitable for access-control integrations where an electric strike releases the latch on command. Confirm electric strike compatibility with your access control supplier before specifying.
It's an on-the-bench job with the lock off the door - see the full step-by-step above, or our bench-method guide for the same procedure across the whole non-ECP Borg range. In short: remove the 4 red screws, lift the cover plate, hold the C-pin depressed, then reposition the red and blue pins with the supplied tweezers. If you'll want to change the code often, Borg's ECP range (like the BL2702SCECP) does it from the keypad in under a minute.
The holdback mechanism is a different inside paddle assembly - it isn't a retrofit add-on for the BL2002SC. If holdback is required, specify the BL2202SC from the outset.
Additional Information
The code can be set on the bench before the lock goes on the door. Set and verify it before mounting - this avoids removing a freshly-fitted lock for the first code change.
Measure the stile before ordering. The 28mm backset latch needs a faceplate pocket of 96mm height × 26mm width morticed into the edge. Our stile measuring guide covers exactly what to check. If your stile is wider than 40mm, a standard 60mm backset latch is likely suitable and may give more secure bolt engagement.
The 28mm latch is a handed part, not a field-reversible one - the confirmed spare-latch options are sold as separate Left Hand and Right Hand SKUs. Our door handing guide explains how to work out which one you need if you're ordering a spare latch down the track.
On-the-bench code changes are the trade-off for this model's lower price point. If your gate or door sees shared use - staff turnover, holiday letting, a shared side gate - the extra cost of an ECP model usually pays for itself the first time you don't have to pull the lock off the door to re-code it. The BL2702SCECP keeps the same 28mm narrow-stile latch format.
The gate post is the fixed frame the gate closes against; the gate stile is the vertical edge of the gate leaf itself that carries the lock. It's the stile width that determines whether a 28mm or 60mm backset latch will fit - our narrow stile guide opens with exactly this distinction before walking through the fitting options.
All Borg locks are warranted against mechanical defects in materials and workmanship under normal use and service for a minimum of 12 months from date of sale. The warranty does not cover damage arising from misuse, vandalism, or improper installation. The lock must not be dismantled - doing so will invalidate the warranty.

Borg BL2002SC - FAQ, Setup and Owner's Guide
For the wider picture, see Buyer's Guide Chapter 16 - Mech-Digi on Gates and our full narrow stile guide.
Narrow Stile & Gate Fit
As a rule of thumb, a standard 60mm backset latch needs a stile wide enough to mortice a 60mm-deep pocket without breaking through the back of the frame - that's typically 50x50mm and above for aluminium. Anything narrower, and a 60mm latch simply won't fit. Our two-size-groups breakdown covers exactly where that line sits and how to check your own frame.
There are a few genuine paths, and the BL2002SC covers the most common one. Our full comparison of the four options - short backset latch (this product), forend-fixing gate lock, prefabricated mounting box, or a workshop-fabricated solution - walks through the trade-offs of each.
Yes - the BL2002SC's 28mm mortice latch is the short backset option in Borg's BL2000 range. It's specifically what our short backset write-up recommends as the first thing to check when a standard latch doesn't fit.
Yes, provided it's kept internal or sheltered from direct weather - this product isn't rated for fully exposed external use. For gate-rated, weatherproof mechanical digital locks, see Borg's Marine Grade Pro range, covered in our MG Pro & ECP explained guide.
Holdback, Egress & Handle Function
Yes. There's no holdback on this model, so the paddle handle simply operates freely at all times from inside - you never need a code to get out, and there's nothing to disengage or reset.
Mechanically identical - same 28mm latch, same keypad, same on-the-bench code change. The BL2202SC adds a holdback lever so you can prop the latch open for free passage during, say, a delivery or a working day. If you'll never need that, the BL2002SC's simpler paddle is one less thing to go wrong.
Code Change & Security
Budget 20-30 minutes the first time - it's fiddly, not difficult, and it gets quicker with practice. Our bench-method walkthrough covers the standard-chamber procedure step by step with realistic timing across the whole non-ECP Borg range.
As many as you like - but only one active code at a time. This model doesn't support individual user codes or an audit trail; everyone who needs entry uses the same PIN. If you need to know who came and went, or want separate revocable codes, that's a smart lock feature, not a mechanical digital one.
Take the lock off the door and follow the on-the-bench procedure again - you don't need to know the old code to set a new one, just physical access to the pins inside. Spare pins (BLS213 coded, BLS214 non-coded) are available if any go missing during the process - see our spares guide.
Installation & Compatibility
Confident DIYers regularly fit this style of lock, provided the mortice pocket is already cut or you're comfortable cutting one accurately. If you'd rather not risk a 96×26mm pocket on an expensive aluminium gate, Terry's team can supply and fit it - see our site survey and installation service.
The latch format itself is compatible with electric strikes generally, but strike bodies vary by manufacturer and door/frame construction. Confirm the specific strike model with your access-control supplier or installer before ordering, particularly on a narrow aluminium frame where clearance is already tight.
You'll need to know your door or gate's handing first - the replacement latches are sold as separate Left Hand and Right Hand SKUs, not a universal part. Our door handing guide explains LH/RH and LHI/RHI/LHO/RHO conventions used across the trade.
