If you have been looking at Borg mechanical digital locks, you may have noticed terms like MG Pro, MG Pro 2 and ECP in the product names.

These are not random model codes. They describe important features that can make a big 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.

The simple answer

What does MG Pro mean?

MG Pro means Marine Grade Pro.

This is Borg’s higher-spec external finish and construction for mechanical digital locks used in harsher environments. MG Pro models typically use marine-grade stainless internal components and a black external coating designed to better resist corrosion and environmental exposure.

Some listings also refer to MG Pro 2, which is an improved marine-grade coating formulation with increased protection against saltwater corrosion and UV degradation on selected models.

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.

Where is Marine Grade Pro useful?

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

• External pedestrian gates
• Pool gates
• Beachside homes
• Canal-front and waterfront properties
• Coastal environments
• Marine facilities
• External doors exposed to weather
• Locations where standard finishes corrode prematurely

A standard internal finish may look fine when first installed, but outdoor environments can be brutal on locks that were not designed for them.

This is also why professional-grade outdoor locks are usually a better choice than cheaper generic options for exposed gates. We explain this further in Why Our Range Is Better Than Hardware Store Imitations.

What does ECP mean?

ECP means Easicode Pro.

This is Borg’s on-door or on-gate code change system. Instead of removing the lock from the door and rearranging internal tumblers, ECP allows the PIN code to be changed while the lock remains installed.

On many ECP models, the code can be changed using the included code change key. This makes code changes much easier for homeowners, property managers, locksmiths and commercial sites.

Why does ECP matter?

Mechanical digital locks are often chosen because they are simple, battery-free and reliable. But on older-style mechanical locks, changing the code can be more involved.

Depending on the model, code changes may require the lock to be removed from the door so the internal tumblers can be rearranged. That is fine for some low-use private doors, but it can be frustrating for gates, managed properties, rentals and commercial sites.

• Rental properties changing codes between tenants
• Airbnb and short-stay properties
• Strata or body corporate gates
• Commercial staff changes
• Maintenance or contractor access
• Managed properties where codes are changed regularly

ECP is especially useful when the code may need to be changed without booking a full lock removal and reconfiguration.

For shared gates and common access areas, also consider whether free access functions such as passage mode or holdback mode are appropriate. We cover this here: Passage Mode vs Holdback Mode.

MG Pro vs ECP: they are different features

A common point of confusion is that MG Pro and ECP describe two different things.

What does MG Pro ECP mean together?

When you see a Borg lock described as MG Pro ECP, it usually means the lock combines both features:

• MG Pro for marine-grade external durability and corrosion resistance
• ECP for easier on-door or on-gate code changing

This combination is very useful for external gates and coastal properties where the lock needs to survive the environment and the code may need to be changed from time to time.

For example, many Borg gate lock models use the MG Pro ECP combination because gates often face both problems: weather exposure and the need for practical code management.

Do you always need MG Pro?

No. You do not always need MG Pro.

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.

However, if the lock is going outside or near a harsh environment, MG Pro can be a smart investment.

If the lock is for a gate, make sure you also consider gate design, post size and latch type. These guides may help: Gate Post Too Narrow for a 60mm Latch? and Why Magnetic Gate Latches Can Be Problematic.

Do you always need ECP?

No. You do not always need ECP either.

Some standard Borg mechanical digital locks use a tumbler-based code system where the lock needs to be removed to change the code. That can still be perfectly suitable if the code is rarely changed.

ECP becomes more valuable when code changes are likely to happen during the life of the lock.

Example: why MG Pro ECP is popular on gates

Gates are one of the best examples of why these features matter.

A gate may be exposed to rain, salt air, humidity, pool chemicals and UV. It may also be used by multiple people, including residents, cleaners, gardeners, trades or tenants. That means both environmental durability and easy code changes can be important.

A Borg MG Pro ECP gate lock gives you a mechanical, battery-free keypad lock with improved external protection and easier code management.

Gate security is not only about weather resistance. If the gate can be reached over or through, you may also need to consider a double-sided keypad lock. Read more here: Why Double-Sided Digital Mechanical Locks Are a Smart Choice for Gates.

Quick comparison

So which one 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 corrosion resistance and easy code changing.
• 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.
