MG Pro & ECP Explained: What Do They Mean on Borg Mechanical Digital Locks?

Two terms appear on Borg mechanical digital locks constantly — one is about surviving the weather, the other is about changing the code.

If you have been looking at Borg mechanical digital locks, you will have noticed terms like MG Pro, MG Pro 2 and ECP in the product names. These are not random model codes — they describe features that make a real difference to where the lock should be used and how easy it is to manage long term.

In simple terms, MG Pro relates to outdoor and corrosion resistance, while ECP relates to easier code changing.

This guide covers:

• What MG Pro, MG Pro 2 and ECP actually mean, in plain English
• Where marine grade protection genuinely earns its keep — and where it is unnecessary
• How salt spray hours work, and what 1,000+ hours actually buys you
• How Borg's on-door code changing compares with the other brands' methods
• How to read a full model name like MG Pro ECP and choose confidently

If you are new to this style of lock, start with the main guide on what a mechanical digital lock is and come back.

The Simple Answer

Quick takeaway: MG Pro helps the lock survive harsher environments. ECP makes the lock easier to manage when the code needs to be changed. They are separate features — a lock can have one, both, or neither.

What Does MG Pro Mean?

MG Pro means Marine Grade Pro.

This is one of the reasons Borg is often compared differently to other mechanical digital lock brands. For a broader comparison, see Lockwood vs Borg vs Carbine mechanical digital locks.

In plain English: MG Pro is the version you look at when the lock is going outside — near salt air, around pools, on gates, or into harsher weather.

What Does MG Pro 2 Mean?

Some listings also carry MG Pro 2 — an improved marine-grade coating formulation with increased protection against saltwater corrosion and UV degradation, used on selected models. It carries the same published 1,000+ hour salt spray rating as MG Pro, with 316-grade stainless internals, and sits at the top of Borg's environmental specification.

You do not need to agonise over MG Pro versus MG Pro 2 — the model you are looking at simply comes with whichever formulation Borg builds it with. The decision that matters is marine grade versus standard finish, which comes down to where the lock is going.

Where Is Marine Grade Pro Useful?

MG Pro is most useful where corrosion, moisture, UV exposure and harsh outdoor conditions are real concerns:

A standard internal finish may look fine when first installed, but outdoor environments are brutal on locks that were not designed for them. Coastal gates in particular need the right finish: on the coast the finish is not cosmetic, it is the difference between a lock that lasts and one that seizes. On the Gold Coast, salt air, humidity, pool chemicals and rain exposure all shorten the life of the wrong lock — the coastal factors are covered in depth in how coastal Queensland treats door locks.

This is also why professional-grade outdoor locks are usually a better choice than cheaper generic options for exposed gates — we explain the difference in why our range is better than hardware store imitations.

Pool safety barrier gates: a gate forming part of a pool barrier must self-close from any position and self-latch automatically. A mechanical digital lock can be part of a compliant setup — including with holdback engaged — so long as it is partnered with a compliant self-latching pool latch such as the D&D MagnaLatch, which provides the high-level latch release the barrier rules require. That combination is one we are comfortable fitting. Final approval always rests with a licensed pool safety inspector — have the gate certified before you rely on it.

Salt Spray Hours Compared: What 1,000+ Actually Means

Corrosion resistance on Australian lock hardware is measured by salt spray testing under AS 4145.2 — the lock sits in a chamber of continuous atomised salt fog, and the rating is how many hours it survives without significant corrosion. The standard groups the results into categories, and the two numbers worth knowing in this market:

• 240 hours rates as C7 “High” — the level Carbine publishes for its lockset testing
• 1,000 hours reaches C10 “Extreme”, the top of the scale — the level Borg publishes for the MG Pro range

An honest note on what these numbers do and do not promise: a salt spray chamber is a deliberately severe accelerated test, and hours in the chamber do not convert neatly into years on a gate. Real-world life depends on how exposed the installation is, how close to the surf, and whether the lock ever gets a rinse. What the rating does tell you is relative capability — a C10 Extreme lock has demonstrably more corrosion headroom than a standard finish, and on an exposed coastal gate that headroom is what you are paying for. Carbine's own published salt spray testing note explains the test-versus-installed-reality distinction well, and it applies to every brand's numbers equally.

The Buyer's Guide covers the full grading system — see the C corrosion grades explained and AS 4145.2 mechanical lock grading.

What Does ECP Mean?

ECP means Easicode Pro.

In plain English: ECP means you can change the code without taking the lock off the door or gate.

Why On-Door Code Change Matters

Mechanical digital locks are chosen because they are simple, battery-free and reliable. But on older-style mechanical locks, changing the code is more involved — depending on the model, the lock may need to come off the door so the internal tumblers can be rearranged. That is fine for a low-use private door; it is frustrating for gates, managed properties, rentals and commercial sites.

ECP earns its keep wherever codes actually change:

• Rental properties changing codes between tenants
• Airbnb and short-stay properties
• Strata and body corporate gates
• Commercial staff changes, and contractor or maintenance access
• Any managed property where codes are changed regularly

For shared gates and common access areas, also consider whether free access functions such as passage mode or holdback mode are appropriate — covered in passage mode vs holdback mode.

Practical takeaway: if you expect to change the code more than once or twice over the life of the lock, ECP is worth serious consideration. There is a security angle too — because worn keypad buttons gradually reveal which digits are in a code, periodic code changes are good practice on any mechanical digital lock, and ECP removes the main excuse for not doing them.

Three Code Change Methods Compared

Easicode Pro makes most sense when you see what it replaces. The three main brands each change codes differently:

None of these is a flaw — they are different trade-offs. But if code changes are a regular event, the on-door method wins on effort every time. The full step-by-step procedures for all three — with realistic times — are in changing codes on mechanical digital locks. The brand-by-brand picture, including handing, corrosion and best use per model, is in Lockwood vs Borg vs Carbine.

MG Pro and ECP Are Different Things

A common point of confusion: MG Pro and ECP describe two different features.

Important: MG Pro does not automatically mean ECP, and ECP does not automatically mean MG Pro. Some models have one, both, or neither — always check the exact model name.

What Does MG Pro ECP Mean Together?

When a Borg lock is described as MG Pro ECP, it combines both features: MG Pro for marine-grade external durability, and ECP for on-door code changing. This is the super spec — the top of the Borg line — and on the Gold Coast, with salt air on one side of the gate and a steady stream of code changes on the other, it is the one you want.

That combination dominates the gate lock range for a reason — gates face both problems at once. A gate cops rain, salt air, humidity, pool chemicals and UV, and it is often used by multiple people: residents, cleaners, gardeners, trades, tenants. Environmental durability and practical code management both matter, so most of the Borg gate locks we fit are MG Pro ECP models like the BL4401 MG Pro ECP gate lock, the BL3430 back-to-back gate lock, and on standard doors the BL2601 MG Pro ECP knob lock.

Gate security is not only about weather resistance. If the gate can be reached over or through, a keypad on both sides is the smarter setup — see why double-sided locks are a smart choice for gates.

Best of both worlds: MG Pro ECP means the lock is built for tougher external environments and for easy code changes — which is exactly what most exposed gates need.

Do You Always Need MG Pro?

Not always — but on the Gold Coast, you need to seriously consider it. If the lock is going on an internal office door, internal storeroom, cupboard or a dry sheltered area, a marine-grade finish may not be necessary. Anywhere else in this postcode, the salt air gets a vote: if the lock is going outside or anywhere near exposure, MG Pro is the smart investment.

If the lock is for a gate, the frame itself decides a lot — check the stile size and latch type before ordering. Start with what fits a narrow gate stile and why magnetic gate latches can be problematic.

Do You Always Need ECP?

No — but it only costs a few dollars more, and it is worth it. Some standard Borg mechanical digital locks use a tumbler-based code system where the lock comes off the door to change the code — perfectly suitable if the code rarely changes. ECP becomes valuable when code changes are likely during the life of the lock, and given how small the difference in cost is, the first code change usually pays for it.

What These Locks Will Not Do

Mechanical digital locks are reliable, battery-free and honest about what they are. They are not smart locks, and it is worth being clear about the trade before you buy.

Not suitable if you need: individual codes for each person, a record of who came through and when, codes that expire on a schedule, or access you can grant and revoke from your phone. Every mechanical digital lock uses one shared code, and changing it means walking to the door.

One more honest point: over years of use the buttons in the code wear and discolour, which narrows the guesswork for anyone paying attention. Changing the code periodically is worth doing for this reason alone — and it is exactly the habit ECP makes painless.

None of these are faults. They are the trade you accept for a lock that never needs a battery, never loses connection and keeps working through a power outage. If you need per-person access or an audit trail, an electronic lock is the better tool — the full honest comparison is in what mechanical digital locks will not do.

Which Should You Choose?

• Choose MG Pro if the lock is going outside, near the coast, near a pool, or into a harsh environment.
• Choose ECP if you want the code to be easy to change without removing the lock.
• Choose MG Pro ECP if you want both — which is most exposed gates.
• Choose a standard model if the lock is internal, sheltered, low-use and the code is unlikely to change.

The right choice depends on the door or gate, the environment, and how the lock will be managed over time — the same fit-for-purpose thinking behind how our range is curated. Quick decision table:
