Borg BL2600 MG Mechanical Digital Knob Lock - Marine Grade - 60mm Backset - Satin Chrome
The Borg BL2600 MG is a fully mechanical digital knob lock built for outdoor and coastal environments. Designated as Marine Grade (MG), it is constructed to resist the corrosion and UV exposure typical of Queensland gate and outdoor door installations. It operates without batteries and needs no electrical connection or wiring of any kind. It is the entry-level model in Borg's marine grade knob range - browse the full battery-free lineup on our Digital Mechanical Locks category page.
The lock uses a clutching knob mechanism - the external knob remains free-turning until the correct PIN code is entered, preventing forced rotation. The inside lever is always free to turn, giving immediate egress. An anti-thrust deadlatch pin ensures the door or gate secures automatically on closing.
Code change on the BL2600 MG is done On The Bench - the lock has to come off the door, and the red (coded) and blue (uncoded) tumblers inside the keypad are rearranged using the supplied tweezers. It works, but it is a fiddly job, best done once and left alone. Code length can be set between 3 and 7 digits. If you think you might need to change the code more than once, even just once a year, we would point you to the BL2601 MG Pro ECP instead, which lets you reset the code on the door in about 10 seconds.
Usually same day if ordered before 11am AEST (excluding weekends and Queensland public holidays)
The BL2600 MG is rated Marine Grade, meaning corrosion-resistant materials and construction suited to outdoor gates, exposed coastal locations, and environments carrying salt air, moisture and UV exposure. It is the entry tier in Borg's marine grade family - Borg does not publish a salt spray test figure for this standard MG tier, unlike the higher MG Pro and MG Pro 2 tiers, which are both 1,000 hour salt spray tested. See our MG Pro and MG Pro 2 explained guide for the full breakdown of where this model sits.
The BL2600 MG uses Borg's older on-the-bench code system. To change the PIN, the lock has to come off the door, the internal cover plate comes off, and the red (coded) and blue (uncoded) tumblers get rearranged with the supplied tweezers. It is fiddly, tricky work, and not something you want to be doing regularly. For on-door code change with no removal at all, see the BL2601 MG Pro ECP with Easicode Pro - our Changing Codes on Mechanical Digital Locks guide walks through both methods side by side.
The BL2600 MG is entirely mechanical. There is no power source, no wiring, and no battery maintenance. Code entry and latch operation are purely mechanical.
For heavy duty commercial doors, see the Lockwood 3572DX, the Borg BL7701, or the Carbine CDL7100SC-HD.
The BL2600 MG holds one active PIN code at a time. Multiple codes cannot be stored simultaneously.
Installing on a narrow aluminium gate frame?
Planning to mount this lock on an external gate with a 50mm x 50mm aluminium frame?
Worried the standard 60mm latch included in the box will not fit the frame?
You are right, it will not.
To fit correctly on a narrow gate frame you need the short 28mm backset latch instead. See our Gate Post Too Narrow for a 60mm Latch guide if you are not sure which stile width you have.
Left Hand Short Latch (BLS272000LH) Right Hand Short Latch (BLS272000RH)Add the correct handing to your cart now and avoid delays on install day.

BL2600 / BL2601 Marine Grade Series - Product Family
This product (bold row) is the entry-level model in the BL2600/BL2601 marine grade knob family. Both siblings share the same 60mm tubular latch platform and clutching knob mechanism - the difference is coating grade and code-change method, not the lock body itself. Borg's BL2600 family also has a separate, unrelated back-to-back tier under the same "2600" family number - see BL2620MGBC, an External Grade knob/knob back-to-back lock in polished chrome. It is not a finish variant of this product; it is a different door format on a different grade tier.

Frequently Asked Questions
The code is changed on the bench, with the lock off the door. Turn the keypad over, remove the two red cover plate screws, then press and hold the C button. Use the supplied tweezers to rearrange the red coded tumblers and blue uncoded tumblers to set your new code. Refit the cover plate, put the lock back on the door, and test the new code several times before closing the gate or door. Write the new code down somewhere safe, the Code Card is a good spot.
Both are marine grade mechanical digital locks. This BL2600 MG uses Borg's older on-the-bench code system, so the lock has to come off the door to change the code, and it is fiddly work. The BL2601 MG Pro ECP uses Easicode Pro, letting you change the code on the door using the included code change key, no removal required, and adds the higher MG Pro 2 coating with a published 1,000 hour salt spray rating on top. If you expect to change the code more than once, even just once a year, we would steer you to the ECP version instead.
The 60mm backset latch supplied in the box is sized for a standard door or gate leaf. On a narrow aluminium gate frame (50mm x 50mm or similar), the standard latch will not sit correctly. You need the extended gate latch, BLS272000LH or BLS272000RH depending on handing. Not sure what you have? Our guide to measuring your gate stile walks through it.
Yes. This lock is non-sequential. If the code is set to buttons 1, 2, 3, 4 and 5, the lock will open once all five of those buttons have been pressed, whatever order they go in. That means the code can be pressed 5-4-3-2-1, 3-1-5-2-4, or any other sequence, as long as every coded button gets pressed before you turn the knob.
The lock's job is access control, not the barrier's self-latching function. Our site-wide position is straightforward: a bolt-format lock is never allowed on a pool barrier gate, because a bolt does not secure anything until it is thrown, but a self-latching latch lock like this one is fine so long as a genuinely compliant self-latching gate latch (such as a MagnaLatch) is doing the barrier's self-latching job. See the full pool safety barrier gate treatment in our latch vs bolt guide, and get final sign-off from a licensed pool safety inspector before you specify any lock for a pool gate. Terry's can advise on the correct latch handing and installation approach for your specific gate.
Additional Information
The lock ships with a factory preset code shown on the Code Card included in the box. We strongly recommend changing the code before you install the lock. On-the-bench code changes need the lock off the door, so it is far easier to do on the bench before fitting. Once installed, any future code change means taking the lock off the gate or door and doing the whole tumbler process again.
Because the code is non-sequential, nobody can learn it just by watching the order buttons are pressed. Button wear patterns over time can still hint at which buttons are in use, though. Where the code's security really matters, change it periodically and spread the coded buttons across the keypad rather than grouping them together.
Despite the marine grade construction, periodic maintenance extends the lock's service life in coastal environments. Monthly: wipe the keypad and latch with a silicon-based lubricant (such as GT85) and remove the excess with a soft cloth. Do not use oil-based lubricants such as WD-40, they attract dirt and wear down internal parts over time. Annually: remove the lock, spray internally through the tumbler holes with silicon-based lubricant, and test all buttons and the knob. See the Borg Lock Servicing Guide PDF below for full servicing steps.
The anti-thrust pin beside the latchbolt deadlocks the bolt when the door or gate closes. It is important the anti-thrust pin does not enter the hole made for the latchbolt in the strike plate. If it does, adjust the strike plate position so the pin sits flat on the face of the strike plate instead. Check this at installation, before the gate goes into regular use.
We stock Borg alongside Lockwood and Carbine because the corrosion story is honest and comparable brand to brand, not just marketing copy. See our Lockwood vs Borg vs Carbine comparison, and our note on why the curated Borg range beats hardware-store imitations on latch quality and corrosion resistance. Our full Mechanical Digital Locks buyer's guide covers all three brands we stock side by side.
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 from misuse, vandalism, or improper installation. The lock must not be dismantled, doing so will invalidate the warranty.

Borg BL2600 MG - FAQ, Setup and Owner's Guide
The most common questions we get about the Borg BL2600 MG, grouped by topic. For the general basics of a keypad lock, see our Mechanical Digital Locks buyer's guide.
Marine Grade and Code Change Explained
It is the entry tier. Standard Marine Grade, used here, is Borg's base coastal finish with no published salt spray figure. MG Pro steps up to 316 stainless steel construction with a 1,000 hour salt spray rating. MG Pro 2 carries the same 1,000 hour rating with an improved UV-resistant coating on top. See the full breakdown in our MG Pro and MG Pro 2 explained guide.
It is not difficult once you have done it, but it is fiddly, it needs the lock off the door, and most people only want to do it once. If there is any realistic chance you will need to change the code again, a rental, a strata property, staff or tenant turnover, we would steer you to the BL2601 MG Pro ECP instead. Full steps for both methods are in our Changing Codes on Mechanical Digital Locks guide.
We have not found one in any Borg documentation for the standard MG tier. That is a genuine gap in what Borg publishes, not something we are hiding, and it is exactly why we flag it plainly on this page rather than guessing a number. If a tested, published salt spray figure matters to your specification, the MG Pro and MG Pro 2 tiers both carry a confirmed 1,000 hour rating.
Gate and Narrow Frame Installation
Measure the stile, the vertical bar of the gate frame the lock mounts into, not the gate post. Most standard aluminium and timber gate stiles take the 60mm backset latch this lock ships with. Narrow aluminium stiles around 50mm x 50mm need the shorter 28mm backset latch instead (BLS272000LH or RH). Our measuring guide walks through it with photos.
Yes. The short 28mm backset latch is handed and sold as a left hand or right hand part (BLS272000LH / BLS272000RH), unlike the standard 60mm latch on this lock, which is reversible on site. Our gate stile guide explains how to work out which hand you need before ordering.
Pool Gates and Compliance
No, not on its own. A pool barrier gate needs its own certified self-latching, self-locking hardware, typically a compliant MagnaLatch or similar, doing the barrier job. This lock provides access control on top of that, not instead of it. Bolt-format locks are never acceptable on a pool barrier gate at all, since a bolt secures nothing until someone deliberately throws it. See the full position in our pool safety barrier gate guide.
Only if a compliant self-latching latch, such as a MagnaLatch, is separately fitted and doing the barrier's self-latching job. This lock's own holdback function is an access-control convenience, not a barrier safety feature. See our Passage Mode vs Holdback Mode guide for the full ruling on pool gates and holdback.
Fit, Compatibility and the Wider Range
No. This lock has no key override at all, by design, access is PIN code only. If you want a marine grade Borg knob lock with a backup key, that is a different lock body and format entirely, not a variant of this product, so speak to Terry's about the alternatives.
No, despite the similar name. This BL2600MGBC is a single-sided Marine Grade knob lock in satin chrome. BL2620MGBC is a completely different product, an External Grade knob/knob back-to-back lock in polished chrome, for doors and gates that need a keypad on both sides. Both happen to carry the "2600" family number, but they are not finish variants of each other.
