Borg Mech-Digital BL3572KIT Adaptor Kit - Lockwood 3572 Mortice Lock - Suits 2000 and 4000 Series Keypads
The Borg BL3572KIT is a stainless steel adaptor kit that lets a Borg 2000 or 4000 Series mechanical digital keypad work the Lockwood 3572 mortice lock a door already has. It is the Lockwood 3572 conversion in the Borg 2000 Series accessories range, and one of the Lockwood conversions in our Scar & Adaptor Plates category.
Order the kit with one Borg keypad-only unit, such as the BL2000KSCNEW knob keypad or the BL2301KSC lever keypad. The keypads we stock for it are listed under What This Kit Converts and the Keypads It Takes, and the wider range is in Keypads for Smartlocks. New to battery-free keypad locks? Start with what a mechanical digital lock is.
Usually ships same day if ordered before 11am AEST (excludes weekends and Queensland public holidays).
Key Features
- Converts the Lockwood 3572 mortice lock to Borg code entry, so the lock the door already has stays in service - the retrofit approach behind our mech-digi range.
- Takes Borg 2000 and 4000 Series keypad-only units, knob or lever - from the BL2000KSCNEW knob keypad to the BL4401KMGPRO 4000 Series lever keypad (full list under Compatibility).
- Single keypad conversion - for a Borg keypad on each side of the door, the back-to-back (BTB) kit BL3572KITBTB is the Lockwood 3572 kit to order.
- Need a key override? The Lockwood 3572 key override conversion in the same range is the 09351550 (BL3572KOR) adaptor plate.
- Using a Borg 5000 Series keypad instead? The 5000 Series kit for the Lockwood 3572 is BL50013572K.
- Code changing follows the keypad you choose: Easicode Pro (ECP) keypads change on the door, and standard Borg keypads change On The Bench (Borg standard chambers).
- Spare spindles available: the standard BLMORTSPDL and the extended BLMORTSPDL120 for thicker doors.
Suitable Uses
- Doors fitted with a Lockwood 3572 mortice lock that are moving to Borg keypad entry - check the lock on your door against our existing door hardware guide first.
- Commercial doors running a Lockwood 3572 where a battery-free Borg keypad suits the job - read commercial and heavy duty mech-digi before choosing the keypad, or compare the Lockwood DX mortice route.
- Retrofit jobs that keep the existing Lockwood 3572 in the door, as an alternative to a complete lock from our Digital Mechanical Locks range.
- Pairing with a Borg keypad-only unit from our Keypads for Smartlocks range - knob or lever, standard or Easicode Pro.

What This Kit Converts and the Keypads It Takes
BL3572KIT converts the Lockwood 3572 mortice lock and takes one of the Borg 2000 and 4000 Series keypad-only units below - choose by knob or lever, finish and code-change method. If you choose an Easicode Pro (ECP) keypad, ask us to confirm it with this kit before you order. The complete BL2000SC lock and Lockwood's own 3572DX are listed for comparison.

Frequently Asked Questions
One of the Borg 2000 and 4000 Series keypad-only units in the compatibility table - for example the BL2000KSCNEW knob keypad, the BL2301KSC lever keypad, or the BL2401KSCECP if you want Easicode Pro (ECP) code changes on the door. Order the keypad alongside the kit.
They convert different Lockwood mortice locks, so match the kit to the lock in your door: BL3572KIT is the Lockwood 3572 conversion and BL3582KIT is the Lockwood 3582 conversion. Both are sold for Borg 2000 and 4000 Series keypads. Not sure which lock you have? Start with our existing door hardware guide, or ask our team through the Qualified Locksmith Recommendation page and we will help you confirm it.
Yes - choose the 09351550 (BL3572KOR) adaptor plate, which Borg sells as the Lockwood 3572 conversion with key override, for the same 2000 and 4000 Series keypads. Read why key override can be important, and if you would rather a complete Lockwood keypad lock with key override, compare the Lockwood 3572DXKO.
Order the back-to-back (BTB) kit instead: BL3572KITBTB is the Lockwood 3572 kit for a Borg keypad on each side of the door. Read what a double-sided lock is first - a keypad on the inside means a code is needed to get out as well as in, so it is not for required exit paths.
Thicker doors take the extended spindle. Two spindles are available: the standard BLMORTSPDL and the extended BLMORTSPDL120 for thicker doors. Measure your door with our door thickness guide and tell us the figure - we will confirm which spindle your conversion needs.
Additional Information
- Retrofit rather than replace: BL3572KIT is one of the Borg retrofit parts we stock, with the keypad-only units in Keypads for Smartlocks and the adaptor kits and scar plates in Scar & Adaptor Plates. See the retrofit ecosystem and why spare parts support matters.
- Pick the keypad for the code changes you expect: the code-change method belongs to the keypad, not the kit. Easicode Pro (ECP) keypads change on the door; standard keypads change On The Bench. If you expect to re-code even once a year, choose an ECP keypad (see do you always need ECP).
- Check before you order: confirm the lock in your door is a Lockwood 3572, note whether the door has mortice lever and escutcheon or mortice longplate furniture, and measure the door thickness so we can confirm the spindle. Not sure? Ask our team for a recommendation.
- Professional fitting: we recommend a locksmith for a mortice conversion unless you are confident with mortice hardware - see when DIY is appropriate. On the Gold Coast we offer professional supply and installation, and our Advice and Installation page is the place to start.
- The complete-lock alternative: if a conversion does not suit, Lockwood's own 3572DX Digital DX keypad mortice lock is a complete keypad lock on the same 3572 platform - read about the Lockwood DX mortice route and compare Borg and Lockwood code-change methods.
Warranty
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. Proof of purchase required for all claims.

BL3572KIT - FAQ, Fitting and Buying Guide
Answers for converting a Lockwood 3572 mortice lock to a Borg keypad with BL3572KIT. For the bigger picture, read Buyer's Guide Chapter 16 - Mechanical Digital Locks and the general questions in Chapter 13 - Smart Lock FAQ.
Choosing Between Kits
Convert if the Lockwood 3572 is staying: BL3572KIT and a Borg keypad-only unit put Borg code entry on the lock you already have. If you would rather replace it with a complete keypad lock on the same platform, Lockwood's own 3572DX is the Digital DX mortice lock and the 3572DXKO adds key override. Compare how Borg and Lockwood code changes differ, and read the Lockwood DX mortice route for commercial doors.
Match the kit to the keypad series. BL3572KIT is sold for Borg 2000 and 4000 Series keypads; for a 5000 Series keypad on a Lockwood 3572, order BL50013572K, or BL50013572KBTB for a keypad on each side of the door. You can browse scar and adaptor plates in our Scar & Adaptor Plates category.
Keypads and Code Changes
The Easicode Pro (ECP) keypads in this kit's compatibility list: the BL2201KSCECP and BL2401KSCECP, and the 4000 Series BL4401KMGPROECP. ECP is Borg's on-door code change - see what ECP means and the Borg Easicode Pro on-door change. If you expect to re-code regularly, even once a year, choose one of these, and ask us to confirm your ECP keypad with the kit before you order.
On The Bench. The standard (non-ECP) keypads - BL2000KSCNEW, BL2000KPB, BL2301KSC, BL2600KMG, BL2601KMGPRO and BL4401KMGPRO - are re-coded off the door rather than on it. See Borg standard chambers, the bench method and how long a code change really takes, or when to call a locksmith.
Look at the external grade and Marine Grade Pro (MG Pro) keypads in this kit's compatibility list: the external grade BL2600KMG, and the MG Pro BL2601KMGPRO, BL4401KMGPRO and BL4401KMGPROECP. See what MG Pro means and internal, external and marine grade options, then tell us how exposed the door is so we can confirm the whole conversion suits it.
Fitting, Spares and Support
We recommend a locksmith for a mortice conversion unless you are confident working on mortice locks. Check when DIY is appropriate and the most common DIY installation mistakes first. On the Gold Coast, book professional supply and installation or a free site survey, or start at our Advice and Installation page.
Both mortice spindles are available as BDS spares: the standard BLMORTSPDL and the extended BLMORTSPDL120 for thicker doors. BLMORTSPDL120 is a special order item - read its special order note before ordering. See why spare parts support matters for a mechanical digital lock.
No - Borg mechanical digital keypads are fully mechanical, with no batteries and no app. Read how a mechanical digital lock works and how it compares with a smart lock, weigh up mechanical vs smart in Chapter 16, and check what these locks will not do before you choose. Borg's battery-free approach is covered in our Borg brand profile.
