Borg BL3430 MG Pro ECP Mechanical Digital Gate Lock - Back-to-Back Keypads - Marine Grade Pro - Easicode Pro - Black
At A Glance
Not Available
The Borg BL3430 MG Pro ECP is a fully mechanical digital gate lock with keypads on both sides of the gate - the correct PIN is required to enter and to exit. It is the Marine Grade Pro, Easicode Pro member of Borg's purpose-built metal gate lock family: the entire external surface is finished in Borg's MG Pro black marine external grade coating, tested to 1,000 continuous hours of salt spray, so it is built for coastal gates that destroy ordinary powder-coated hardware. For what the MG Pro and ECP suffixes mean across the Borg range, see our plain-English guide to MG Pro and ECP decoded.
Easicode Pro (ECP) is the on-gate code change system: the PIN is changed in minutes with the supplied change key while the lock stays on the gate - no removal, no workbench, no tumbler tweezers. The 14-button keypads accept over 4,000 non-sequential code combinations, entered in any order. Because there is no wiring and no battery, there is nothing to go flat and nothing to corrode electrically - the trade-off every mechanical digital lock makes is a single shared PIN with no audit trail.
The lock mounts with Borg's forend fixing system: two telescopic through-bolt fixings clamp the unit straight onto a square metal gate post from 30mm to 60mm - no mortice cutting and no door-edge drilling. The spring-loaded latch bolt self-latches as the gate swings closed and adjusts from 65mm to 80mm projection, and the housing carries an anti-climb design that offers no external foothold. Handing is reversible on site. For where mechanical digital locks dominate on gates, see Buyer's Guide Chapter 16 - Gates.
Usually ships same day if ordered before 11am AEST (excludes weekends and Queensland public holidays).
The BL3430 clamps directly onto a square aluminium or steel gate post using Borg's forend fixing system - through bolts pass through the post and secure the lock body firmly, with no mortice cutting required. Standard fixings suit posts from 30mm to 60mm square; wider posts can be accommodated with a latch extension and round posts with the Borg round post kit. See the Forend Fixing System section below for the exploded diagram.
The full external surface is finished in Borg's MG Pro black marine external grade coating, tested to 1,000 continuous hours of salt spray exposure. This is the coating tier above the standard marine grade models in this family, which pair marine grade keypads with a Black Powder Coat housing. For what the salt spray test actually measures, see salt spray testing explained.
Borg warrants the corrosion resistance of the MG Pro coating for 12 months from date of sale under specified conditions, in addition to the standard mechanical warranty. Simple monthly lubrication keeps coastal installations well inside those conditions - see the maintenance note under Additional Information.
The PIN is changed while the lock is installed on the gate, using the supplied Easicode Pro change key - no lock removal and no tools. An optional code change disabling plug blocks the change function where you do not want on-site staff altering the code. See the code change section below, and how Easicode Pro compares with tumbler code changes.
Both keypads require the correct PIN before the lever operates, so entering the code is required to exit as well as to enter. This lock must never be fitted to a fire door, an emergency exit, or any path of travel that requires free egress - and it is not suitable for a pool safety barrier gate, where code-to-exit locking conflicts with barrier compliance requirements (see why keypad locks and pool barriers do not mix). If you need code-controlled entry with a free handle on the inside, choose the single-sided BL3400 MG Pro ECP or BL3400 marine grade instead - our guide to double-sided gate locks and exit paths covers the decision.
Like all mechanical digital locks, the BL3430 holds a single code - everyone who uses the gate shares it, both keypads operate on the same PIN, and there is no audit trail of who came and went. If you need individual user codes or access logs, that is smart lock territory - see what mechanical digital locks will not do.
The lock is entirely mechanical. There is no power source, no cabling to run to the gate, and no battery to go flat in the rain - one of the main reasons mechanical digital locks remain the default choice for external gates. How it works inside is covered in the coding chamber explained.
The BL3430 is at its best on residential and light commercial gates - side gates, service yards, plant enclosures, complex access gates - where the gate sees regular but not constant use.
For a doorway or gate cycling all day, every day, step up to a heavy duty mechanical digital lock: the Borg BL7701 heavy duty lever/lever or, for a code-both-sides format like this one, the Carbine CDL7200 dual keypad heavy duty. What separates heavy duty hardware is explained in heavy duty commercial mechanical digital locks.
Access Methods
Key Features
- Back-to-back 14-button keypads - the correct PIN is required to enter and to exit the gate.
- Marine Grade Pro (MG Pro) black marine external grade coating, tested to 1,000 continuous hours of salt spray.
- Easicode Pro (ECP) on-gate code change using the supplied change key - no lock removal, no workbench.
- Over 4,000 non-sequential code combinations; digits can be entered in any order.
- Optional code change disabling plug blocks the code change function where required.
- Free-turning clutched lever - the handle spins without engaging until the correct code is entered, so force on the lever cannot open the gate.
- Forend fixing system - two telescopic through-bolt fixings clamp the lock to the gate post; no mortice cutting.
- Suits square gate posts from 30mm to 60mm on standard fixings; latch extensions and a round post kit are available for other profiles.
- Spring-loaded latch bolt, self-latching on gate close, adjustable from 65mm to 80mm projection.
- Anti-climb housing design - no external foothold for scaling the gate.
- Security fixings and 20mm bolt withdrawal.
- Cast housing and lever with stainless steel buttons.
- Fully mechanical - no batteries, no wiring, nothing to go flat.
- Handing easily reversible on site.
Easicode Pro - Changing the Code on the Gate
Easicode Pro is the reason property managers specify this model over the tumbler-chamber versions. On the standard marine grade models the lock comes off the gate and the code is changed at a bench with tweezers; on the BL3430 MG Pro ECP the whole job happens on the gate in a few minutes with the supplied change key. With the gate open, enter the current code, insert the change key at the code change button and rotate, clear the old code, enter the new digits, then remove the key and test the new code several times before closing the gate. The code is non-sequential - the digits can be pressed in any order.
Forend Fixing System - How the Lock Mounts
Unlike a door lock, the BL3430 never needs a mortice pocket. The lock body sits on the face of the gate post and two telescopic through-bolt fixings pass right through the post, clamping the unit firmly from both sides - a front collar and sleeve assembly on the keypad side, and a rear collar fitted from the post's rear side. Standard fixings suit square posts from 30mm to 60mm. If your post sits outside that range, measure before ordering - our guide to measuring the gate stile and the forend fixing option walk through it, and the accessories table below lists the latch extensions and round post kit.

Frequently Asked Questions
The lock body sits on the face of the gate post and two telescopic through-bolt fixings pass right through the post, clamping the unit from both sides with a rear collar fitted from the post's rear side - no mortice pocket and no door-edge drilling. The spring-loaded latch projects from the lock body into a strike on the closing post, and its projection adjusts from 65mm to 80mm with the supplied hex key. See the exploded diagram in the Forend Fixing System section.
On the gate, in minutes: with the gate open, enter the current code, insert the Easicode Pro change key at the code change button and rotate, clear the old code, press in the new digits, then remove the key and test the new code at least five times before closing the gate. The code is non-sequential, so the digits can be pressed in any order. A spare change key is available, and an optional disabling plug can block the change function entirely.
No. A pool safety barrier gate must allow unimpeded exit from the pool area, and this lock requires the correct code to exit - the two requirements conflict, so the BL3430 is not suitable for a pool barrier. If a keypad lock is wanted near a pool area, it belongs on a gate that is not part of the safety barrier, or consider a single-sided model with a free inside handle and confirm the whole barrier system with a licensed pool safety inspector first. The latch-versus-barrier question is unpacked in latch vs bolt on pool gates.
Same back-to-back gate lock format, two upgrades: the BL3430 MG Pro ECP carries the full Marine Grade Pro external coating (1,000 hour salt spray tested) and Easicode Pro on-gate code change with over 4,000 combinations. The BL3430GATE is the standard marine grade version - the code is changed at a bench with the tumbler system (over 1,000 combinations). Choose the MG Pro ECP for coastal exposure or wherever codes are changed regularly on site.
Measure the post before ordering. For wider square posts a 50mm latch extension is available - the Easicode-lock extension suits this model - and round posts take the round post kit. Our guide to gate frame size options walks through the measuring.
Additional Information
- Marine grade maintenance: monthly, apply a light spray of silicone-based lubricant (GT85 or equivalent) to the keypads and lever surfaces and wipe off the excess; annually, have the lock serviced internally. The Borg Lock Servicing Guide (PDF) covers the schedule, and coastal lifespan factors are discussed in how long digital locks last on the coast.
- Egress compliance is your responsibility: confirm the gate is not a required exit path or part of a pool safety barrier before fitting a code-both-sides lock. The free-egress alternatives are the single-sided BL3400 MG Pro ECP and BL3400GATE.
- Gate stops and magnetic latches: a moving, slamming gate is the main cause of latch misalignment call-backs. If your gate currently uses a magnetic latch, read why magnetic gate latches can be problematic before the changeover.
- No key override on this model: if the code is lost, the lock cannot be bypassed with a key. Where a keyed fallback matters, choose the BL3430DKO MG Pro ECP - its DKO function takes a euro cylinder (not supplied).
- Handing: the lock reverses on site to suit either hand of gate. Australian handing conventions are explained in understanding door handing.
Warranty
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, including the corrosion resistance of the MG Pro coating under specified conditions. The warranty does not cover damage arising from misuse, vandalism, or improper installation, and the lock must not be dismantled beyond the documented code change procedure.

Borg BL3430 MG Pro ECP - FAQ, Setup and Owner's Guide
Everything below is here to help you buy, install, set up and live with your Borg BL3430 MG Pro ECP gate lock. For the full mechanical digital picture, see Buyer's Guide Chapter 16.
Codes and Easicode Pro
Easicode Pro (ECP) is Borg's on-door code change system. On the standard-chamber gate locks, changing the code means unbolting the lock from the gate and repositioning tumblers at a bench with tweezers; with ECP, the supplied change key does the whole job on the gate in minutes. On strata gates, holiday rentals and managed sites where codes turn over regularly, that difference is the entire buying decision. The full comparison of Borg's code change methods is in MG Pro and ECP explained.
Both keypads operate on the same single PIN - one active code at a time, shared by everyone who uses the gate. There is no per-side or per-user coding, and no record of who entered. If individual codes and audit trails matter, that is smart lock territory - the honest trade-offs are laid out in mechanical digital vs smart lock.
The lock reads which buttons are pressed, not the order they are pressed in - a code of 2-4-6 opens with 6-2-4. That is how the mechanical coding chamber works, and it is why the combination count is quoted as combinations rather than permutations. The mechanics are unpacked in any-order codes explained.
The optional disabling plug blocks the code change function at the keypad, so on-site staff or residents cannot alter the code even with access to a change key. Managed sites fit it after commissioning; leave it out if you want the code freely changeable.
Yes - the spare Borg Easicode change key (BL2000ECPCK) is a stocked accessory and suits the Easicode Pro system on this lock.
Gate Fit and Installation
Standard fixings suit square metal box-section posts from 30mm to 60mm. Measure the post width (the face the lock mounts to) and the post depth (the direction the through bolts pass), and check nothing obstructs the bolt path. Wider posts take a 50mm latch extension and round posts take the round post kit - both in the accessories table on the Description tab. The measuring routine is in measure the stile first.
The spring-loaded latch adjusts between 65mm and 80mm using the supplied hex key - anti-clockwise to increase the projection, clockwise to reduce it. The latch position itself can also be adjusted by removing the two side screws. Both procedures are illustrated in the series instructions (PDF).
Yes, the lock is easily reversed on site to suit either hand of gate; units are factory-set for a right-hand hung gate, and handing is always taken from the outside. The handing chart is in the series instructions PDF, and the Australian conventions are explained in how to determine handing.
Yes. Gates move, sag and slam in wind, and a gate that has been living on a forgiving magnetic latch often needs a gate stop and alignment attention before a mechanical latch and strike will engage sweetly every time. Read the two kinds of magnetic latch before the changeover.
Yes - the spring-loaded latch bolt is bevelled and self-latches as the gate swings closed against the strike, so the gate secures without a deliberate action. Note that self-latching alone does not make a gate pool-barrier compliant on this model, because the code-to-exit keypads conflict with barrier egress requirements - see the Egress and Compliance questions below. The self-latching mechanics are covered in latch vs bolt - self-latching.
Egress, Safety and Compliance
Because a person on the inside cannot leave without the PIN. That is exactly what back-to-back buyers want on a plant yard or waterfront gate - climbing over is defeated by the anti-climb housing and reaching over to a free handle is defeated by the inside keypad - but it also means the gate can never be part of a required exit path. The full picture is in why double-sided gate locks exist and exit paths explained.
Never. A lock that requires a code to exit must not be fitted to any fire door, emergency exit, or required path of travel - no exceptions. See why keypad locks and fire doors do not mix.
Not on the safety barrier. A pool barrier gate must allow unimpeded exit from the pool area, and a code-to-exit lock conflicts with that requirement, so the BL3430 is not suitable for pool safety barrier gates. Keypad control near a pool belongs on gates outside the barrier - and any barrier work should be confirmed with a licensed pool safety inspector. Background: pool gates and latching locks.
The single-sided members of this family: the BL3400 MG Pro ECP (same coating and code system as this lock, keypad outside, free lever inside) or the standard marine grade BL3400GATE. The one caveat with single-sided locks on open-style gates is reach-through bypass - covered honestly in the single-sided problem.
Environment and Durability
The standard models in this family pair 1,000-hour salt water tested marine grade keypads with a Black Powder Coat housing; the MG Pro models carry Borg's full marine external grade coating across the whole lock, tested to 1,000 continuous hours of salt spray. On a coastal gate the coating is what decides whether the lock still looks and works right in year three - see what MG Pro means and how Borg's coating stacks up in Lockwood vs Borg vs Carbine.
Monthly: a light spray of silicone-based lubricant (GT85 or equivalent) over the keypads and lever, excess wiped off. Annually: an internal service. That routine keeps the corrosion warranty conditions met and is set out in the Borg Lock Servicing Guide (PDF). Why maintained mechanical locks outlast neglected electronics on the coast: coastal lifespan guide.
The housing is shaped so the lock body itself offers no foothold for scaling the gate - on a back-to-back installation the units sit flush to the post on both faces with nothing to stand on. Paired with the inside keypad, it closes both of the usual gate bypasses: climbing over the lock and reaching over to a free handle.
Choosing and Comparisons
Choose the BL3430DKO MG Pro ECP if a keyed management override matters - its DKO function adds a euro cylinder key override (cylinder not supplied) with a code lockout function on top of everything this lock does. Stay with the BL3430 MG Pro ECP if you specifically do not want a keyway on the gate - no cylinder to pick, snap, or corrode.
No - this is the metal box-section gate specialist. For wooden and timber gates the back-to-back MG Pro ECP pick is the Borg BL4441 MG Pro ECP (single-sided: BL4401 MG Pro). For sliding doors and gates the hook-bolt Borg BL2606 MG Pro ECP is the marine grade answer (satin chrome, non-marine sibling: BL2506 ECP), and where a horizontal rim deadbolt suits the gate better than a spring latch, see the Borg BL2615 MG Pro ECP.
Probably not. For all-day, every-day cycling, specify heavy duty hardware: the Borg BL7701 heavy duty (single keypad, free egress, SFIC key override) or the code-both-sides Carbine CDL7200 dual keypad heavy duty (100k cycle tested, gate suitable). What "heavy duty" really buys is in high-traffic hardware explained.
An exposed external gate is the one place a mechanical digital lock beats a smart lock almost every time: no battery to die in the weather, no electronics to corrode, no app dependency - just a coated metal mechanism that keeps working. The honest trade is one shared code and no audit trail. Both sides of the argument: why mech-digi dominates on gates and Chapter 16 - mechanical vs smart.
