The Borg BL3400 MG Pro ECP is a fully mechanical digital gate lock built for external metal box-section gates - keypad and free-turning clutched lever on the outside, and a lever that is always free on the inside, so leaving never needs the code. It pairs Borg's two premium upgrades: the full Marine Grade Pro external coating, salt spray tested to 1,000 continuous hours, and Easicode Pro on-gate code change. Where mechanical digital locks dominate on gates - and why - is covered in Buyer's Guide Chapter 16 - Gates.
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 self-latches as the gate swings closed and adjusts from 65mm to 80mm projection, the housing carries an anti-climb design, and the 3400 series' full lever handle is made for pulling a heavy or outward-opening gate - easier than a knob for anyone with limited grip. There is no battery and no wiring, and codes change on the gate in minutes with the supplied Easicode Pro change key.
Where entry AND exit both need the code - plant yards, secure enclosures - step across to the back-to-back BL3430 MG Pro ECP; and where codes rarely change, the tumbler-chamber BL3400GATE does the same single-sided job for less. How Borg's suffixes decode is in MG Pro and ECP explained.

Purpose-Built for Metal Box-Section Gates - Not a Door Lock
The BL3400 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.

Inside Lever Always Free - No Code Required to Exit
The inside lever operates freely at all times, so anyone on the inside can leave immediately without entering a code - the configuration to choose wherever free exit matters. The honest caveat with any single-sided lock on an open-style gate is reach-through: if the inside handle can be reached over or through the gate, the keypad is bypassed. Solid infill or height fixes it, or step up to the code-both-sides BL3430 MG Pro ECP - the trade-off is laid out in the single-sided problem.

Marine Grade Pro - 1,000 Hour Salt Spray Tested
The whole lock carries Borg's black marine external grade coating (MG Pro), tested to 1,000 continuous hours of salt spray - the coating tier to specify for waterfront, beachfront and marina gates. What the MG Pro badge means, and how Borg's coating stacks up against the other brands, is covered in salt spray testing explained and Lockwood vs Borg vs Carbine.

Corrosion Resistance Warranted - 12 Months
Borg warrants the corrosion resistance of the MG Pro coating for 12 months from date of sale under specified conditions - the monthly lubrication and annual service routine in the maintenance notes keeps those conditions met.

Easicode Pro - Change the Code on the Gate, in Minutes
The PIN changes while the lock is on the gate, using the supplied Easicode Pro change key - no lock removal, no tweezers, no bench. An optional code change disabling plug can lock the change function against tampering on managed sites. See the Easicode Pro section below, and the method comparison in Borg code change methods.

Optional Holdback - Free Passage When You Want It
The holdback function holds the latch retracted so the gate swings freely both ways - handy for moving gear through, open days, or trade access. Two firm rules: never leave holdback engaged on a gate that is part of a pool safety barrier (it defeats the self-latching the barrier depends on), and never rely on it for a fire or egress door. The mode is explained in passage mode vs holdback mode.

One Active PIN Code
The keypad holds a single code at a time - everyone who uses the gate shares it, and there is no audit trail of who came and went. If individual codes or access logs matter, that is smart lock territory - see what mechanical digital locks will not do.

Fully Mechanical - No Batteries, No Wiring
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 how a mechanical digital lock works.

Best Suited to Light-Medium Traffic
The BL3400 is at its best on residential and light commercial gates - side gates, complex access gates, service yards - where the gate sees regular but not constant use.

Access Methods
Key Features
- Single-sided: 14-button keypad and clutched lever outside, free lever inside - no code needed to exit.
- Full lever handle - designed for pulling a heavy or outward-opening gate, and easier than a knob for frail hands or anyone with limited grip.
- Free-turning clutched outside lever - the handle spins without engaging until the correct code is entered, so force on the lever cannot open the gate.
- Easicode Pro (ECP) on-gate code change with the supplied change key - no lock removal, no tools, done in minutes.
- Optional code change disabling plug - locks the change function against unauthorised recoding.
- Over 4,000 code combinations; digits can be entered in any order.
- Marine Grade Pro: black marine external grade coating across the whole lock, 1,000 hour continuous salt spray tested.
- Cast housing and handle with stainless steel buttons; anti-climb design with no external foothold.
- Optional holdback function on the inside lever - latch held retracted for free passage; removable if not required.
- 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.
- 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 BL3400 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.
The Easicode Pro change key inserts at the code change button on the keypad - the code is changed with the lock in place on the gate. A spare change key is available separately: Borg Easicode change key (BL2000ECPCK).
Forend Fixing System - How the Lock Mounts
Unlike a door lock, the BL3400 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 - a front collar and sleeve assembly on the keypad side, with 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.

Suitable Uses
- Coastal, beachside and marina pedestrian gates where keyless code-in / free-out access and maximum corrosion protection are both wanted. Browse all digital mechanical locks.
- Residential, duplex and strata side and access gates where the code turns over regularly - the on-gate ECP change is the whole point.
- Holiday rentals and managed properties: recode between guests in minutes, and fit the disabling plug so occupants cannot change the code.
- Heavy or outward-opening gates where the full lever handle makes pulling the gate easy - including for users who find a knob difficult to turn.
- Service yards and equipment enclosures on square metal box-section frames from 30mm to 60mm.
Not a fire-rated door lock, and not for high-traffic commercial entries - see the notes above. On pool barrier gates, whole-of-barrier compliance and inspector sign-off apply, and the holdback function must never be engaged - see the FAQ.
Available Finish Options
Black (Marine Grade Pro)
(This Product)
STK BL3400MGPROECP
Finish selection does not affect functionality, compliance, or performance. Black MG Pro marine external grade coating is the only finish for this model - the standard marine grade version wears Black Powder Coat instead.
Borg BL3100-BL3400 Metal Gate Lock Family
All ten models are purpose-built forend-fixed gate locks for square metal box-section gate frames, fully mechanical with no batteries, finished in black. MG = standard marine grade (marine grade keypads, Black Powder Coat housing, bench tumbler code change). MG Pro = full Marine Grade Pro external coating with Easicode Pro (ECP) on-gate code change. DKO = double key override with code lockout (euro cylinder not supplied).
Locking a metal gate but working with a timber gate elsewhere on site? The Borg BL4441 MG Pro ECP is the back-to-back MG Pro ECP lock for wooden and timber gates, and the BL4401 MG Pro its single-sided sibling. Decoding Borg's model suffixes is covered in Chapter 16 - decoding Borg names.

Frequently Asked Questions
How does the forend fixing system attach the lock to my gate?
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 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.

How do I change the PIN code?
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.

Can I use this on my pool gate?
Its behaviour aligns better than most keypad locks: the latch is self-latching on gate close and the inside lever is always free, so exiting the pool area is never impeded. But pool barrier compliance is a whole-of-system question - gate height, hinges, clearances, non-climbable zones - not just the lock, and the holdback function must NEVER be engaged on a barrier gate because it defeats the self-latching the barrier depends on. Have the complete barrier confirmed by a licensed pool safety inspector before and after installation. Background reading: latch vs bolt on pool gates.

What is the difference between this and the BL3400GATE?
Same single-sided gate lock format, two upgrades: the BL3400 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 BL3400GATE 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.

My gate post is wider than 60mm, or round - what do I do?
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 keypad and lever surfaces and wipe off the excess - never oil-based products; 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.
- Reach-through check before you buy: on an open-style gate, confirm the inside lever cannot be reached over or through the infill - if it can, solid infill, added height, or the back-to-back BL3430 MG Pro ECP closes the gap.
- 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 from outside (the inside lever still exits freely). Where a keyed fallback matters, choose the BL3400DKO 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.

Codes and Easicode Pro
What exactly is Easicode Pro, and why does it matter on a gate?
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.

What does "non-sequential, any order" mean for the code?
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.

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.
What is the code change disabling plug for?
The optional disabling plug blocks the code change function at the keypad, so occupants or on-site staff cannot alter the code even with access to a change key. Managed sites and holiday rentals fit it after commissioning; leave it out if you want the code freely changeable.

I have lost the change key - can I get another?
Yes - the spare Borg Easicode change key (BL2000ECPCK) is a stocked accessory and suits the Easicode Pro system on this lock.

How secure is a shared-code keypad, honestly?
The practical security of a mechanical keypad is less about raw combination count and more about code discipline: change the factory code at installation, avoid obvious patterns, and refresh the code whenever it has been shared widely - which ECP makes a two-minute job. The clutched lever means force on the handle achieves nothing. What these locks will and will not do is covered in the limitations.

Egress, Holdback and Compliance
Is free egress guaranteed - can anyone always get out?
Yes - the inside lever is mechanically free at all times and retracts the latch regardless of the keypad state. That makes this configuration the right pick wherever exit must never depend on knowing a code. The flip side is reach-through on open-style gates, covered honestly in the single-sided problem; where that risk is real, the back-to-back BL3430 MG Pro ECP closes it.

How does the holdback function work, and when should I not use it?
Engaging holdback holds the latch retracted so the gate swings freely both ways - useful for trade access, moving gear, or an open day - and the function is removable if you never want it available. Two hard rules: never leave holdback engaged on a pool safety barrier gate (it defeats the self-latching the barrier depends on), and never rely on a gate lock in any mode on a fire or required egress door. The mode logic is explained in passage vs holdback - pool gates and fire doors.

Where does this lock stand on pool barrier gates?
Better placed than most: self-latching latch, free inside egress, marine coating. But a compliant barrier is a system - gate height, hinge springing, clearances, non-climbable zones - and the lock is only one part, so no lock purchase makes a barrier compliant by itself. Never engage the holdback on a barrier gate, and have a licensed pool safety inspector confirm the complete barrier. The latch mechanics are in latch vs bolt - self-latching.

Gate Fit and Installation
What gate posts does the BL3400 suit, and what should I measure first?
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.

How do I adjust the latch projection?
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).

My gate is hung the other way - can the lock be reversed?
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.

My gate currently closes on a magnetic latch - anything to watch?
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.

Environment and Durability
What does Marine Grade Pro actually add over the standard marine grade models?
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.

What maintenance does a coastal installation need?
Monthly: a light spray of silicone-based lubricant (GT85 or equivalent) over the keypad and lever, excess wiped off - never oil-based products. Annually: an internal service. That routine keeps the corrosion warranty conditions met and is set out in the Borg Lock Servicing Guide (PDF).

What does the anti-climb design do?
The housing is shaped so the lock body itself offers no foothold for scaling the gate - it sits flush to the post with nothing to stand on. On a single-sided installation, pair it with the reach-through check in the notes above so the free inside lever cannot be reached from outside.

Single-sided (this lock) whenever free exit matters or the code only needs to guard entry. Back-to-back - the BL3430 MG Pro ECP - when the gate must be code-controlled in both directions and reach-through bypass has to be closed. The decision logic is in why double-sided gate locks exist.

Should I choose this or the DKO version?
Choose the BL3400DKO 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 BL3400 MG Pro ECP if you specifically do not want a keyway on the gate - no cylinder to pick, snap, or corrode.

My gate is timber, or it is a sliding gate - is this still the right lock?
No - this is the metal box-section gate specialist. For wooden and timber gates the single-sided MG Pro pick is the Borg BL4401 MG Pro (back-to-back: BL4441 MG Pro ECP) - the 4400 series shares this lock's free-turning lever keypad but fixes to timber. For sliding doors and gates the hook-bolt Borg BL2606 MG Pro ECP is the marine grade answer.

The gate is a busy commercial entry - is the BL3400 enough lock?
Probably not. For all-day, every-day cycling, specify heavy duty hardware: the Borg BL7701 heavy duty (single keypad, free egress, SFIC key override - the natural heavy duty step-up from this lock) or the code-both-sides Carbine CDL7200 dual keypad heavy duty. What "heavy duty" really buys is in high-traffic hardware explained.

Why choose a mechanical digital lock over a smart lock for this gate?
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.
