Borg BL2621 MG Pro ECP Mechanical Digital Knob/Knob Lock - Back-to-Back Keypads - Marine Grade Pro - Easicode Pro - Black
The Borg BL2621 MG Pro ECP is a fully mechanical digital lock fitted with keypads on both sides of the door - the knob/knob back-to-back configuration. Entering the correct PIN code is required to open the door from either side, making it the right choice for areas requiring controlled access in both directions. Read what a double-sided digital mechanical lock actually is if you are weighing this up against a single-sided model. It is part of the Marine Grade Pro series, finished in MG Pro 2 black marine grade coating and tested to 1,000 hours of continuous salt spray - see what MG Pro and ECP mean together for the full decode.
The BL2621 MG Pro ECP uses the Easicode Pro (ECP) system for on-door code change without lock removal. An anti-thrust deadlatch pin ensures the door automatically secures when closed. The lock is fully mechanical, requires no batteries, and is cycle tested to 100,000+ operations - double the cycle rating of the single-sided BL2601 model.
For a single-sided version (keypad outside, free lever inside), see the BL2601 MG Pro ECP. For the same knob/knob back-to-back body without marine grade coating or Easicode Pro, see the model range comparison below.
Usually same day if ordered before 11am AEST (excluding weekends and Qld public holidays)
The BL2621 MG Pro ECP has a full keypad unit on both the outside and inside of the door. Both keypads share the same code. This configuration provides controlled access in both directions and is designed for applications where entry and exit must both be code-controlled. See why a single-sided lock is only half a lock on many gates, and the four main benefits of going double-sided.
Unlike single-sided models where the inside lever is always free to turn, the BL2621's inside keypad requires the correct PIN before the inside knob will operate. Occupants cannot exit without knowing the code. This is a deliberate trade-off - see why this design is never suitable for a required exit path - confirm this controlled-exit operation suits your application and complies with any applicable fire egress or building regulations before purchasing.
MG Pro 2 marine grade external coating provides increased protection against saltwater corrosion and UV degradation. Suitable for pool gates, waterfront properties, marina facilities, and coastal environments where standard finishes degrade prematurely. See where Marine Grade Pro is genuinely worth it.
Tested to 1,000 continuous hours of salt spray exposure. Borg warrants corrosion resistance for 12 months from date of sale under specified conditions. See how 1,000 hours compares on the AS 4145.2 corrosion scale, and why a published salt spray figure matters when comparing against unrated hardware-store locks.
The PIN code can be changed on the door using the included code change key - no lock removal required. A code change disabling plug is included to prevent unauthorised code changes once set. Full steps are in Changing The Code below, and in our Borg Easicode Pro walkthrough.
Entirely mechanical. No power source, no wiring, and no battery maintenance at any point in the product's lifetime.
The BL2621 MG Pro ECP accepts one active PIN code at a time. The same code operates both the outside and inside keypads simultaneously.
If you are planning to mount this lock on a gate with a 50mm x 50mm aluminium frame, the standard 60mm backset latch supplied in the box will not fit. You will need the shorter 28mm backset latch instead, sold separately and handed to match your gate: Add the correct gate latch to your cart before ordering to avoid delays at install. See our full gate post and stile sizing guide, including why 60mm is geometrically impossible on a 50mm section.

Model Range - Where This Lock Sits
All six share the same general BL2600 platform DNA (60mm backset, cast housing, stainless buttons) but differ in configuration, finish grade and code-change method. Choose BL2621 where controlled access from both sides is a deliberate requirement; choose BL2601 where free egress from inside is required; choose BL2620MGBC where marine-grade coating and Easicode Pro are not needed.

Changing The Code
This is Borg's Easicode Pro system - the code changes on the door itself, in about 30 seconds, with no tools and no removing the lock. Compare that to a standard bench-change Borg lock, where changing the code means taking the whole lock off the door - see the on-the-bench method for what that involves, and why On-Door code change is worth paying for if you expect to reset the code more than once in a while.
- With the door in the open position, enter the current code on either keypad.
- Insert the code change key into the hole in the * button and hold it down.
- Press C to clear the existing code.
- Enter your new code.
- Release the code change key.
- Press C to confirm.
- Test the new code at least five times from both sides before closing the door - see why testing before the door closes matters. Both keypads will operate on the new code simultaneously.
Never force the code change key if it feels stiff - that means the wrong current code was entered, not a fault with the key. Forcing it against a wrong code twists the sacrificial code change spindle. See what to do if the change key won't turn, or see the official Easicode Pro instructions (PDF).
Marine Grade Maintenance
Clean both keypad surfaces with a light spray of silicon-based lubricant (such as GT85); wipe off excess with a soft cloth. Do not use WD-40 or oil-based lubricants on this model - the general Borg servicing guide specifies silicon-based products only.
Remove the lock, spray internally through the button holes on both units, and test all buttons and both knobs. Refer to the Borg Servicing Guide (PDF) for full instructions.
Frequently Asked Questions
No. The BL2621's back-to-back configuration means the inside knob only operates when the correct PIN code is entered on the inside keypad. There is no free egress from inside. Anyone inside the secured area must know the PIN to exit. This is by design for applications requiring controlled access in both directions, but it must be confirmed as compliant with any applicable fire egress or building occupancy requirements before installation - see why this design is never suitable for a required exit path.
Yes. Both the outside and inside keypads use the same PIN code. Both keypads also have the same code change capability via Easicode Pro, so the code can be changed from either side using the included code change key.
The BL2601 MG Pro ECP has a keypad on the outside and a free-turning lever on the inside - no code is needed to exit. The BL2621 has keypads on both sides, requiring the code to both enter and exit. The BL2621 is also cycle tested to 100,000+ operations, double the BL2601's 50,000+ rating. Choose BL2621 only if controlled exit is a deliberate design requirement for your application - see when a double-sided lock is worth it.
With the door in the open position, enter the current code on either keypad, insert the code change key into the hole in the * button and hold it down, press C to clear the existing code, enter your new code, release the code change key, then press C to confirm. Test the new code at least five times from both sides before closing the door. Both keypads will operate on the new code simultaneously. Full steps are in Changing The Code above.
Not with the latch it ships with. The standard 60mm backset latch is too long for a 50mm x 50mm aluminium stile - you will need the handed 28mm backset left or right hand latch instead. See Narrow Aluminium Gate Frames above, or our full gate post and stile sizing guide.
Additional Information
The BL2621's back-to-back configuration means occupants must enter the PIN to exit. In most Australian buildings, doors on exit paths are required to be operable without a key or code in an emergency under the National Construction Code (NCC). Confirm with your building certifier or fire safety consultant that this lock's operation is compliant for your specific application and occupancy classification before specifying it on any door that may be part of an exit path. Read the NCC D3D26 rule in plain terms and our Buyer's Guide commercial chapter before specifying.
The BL2621 is cycle tested to 100,000+ operations, compared to 50,000+ for the single-sided BL2601. This higher rating reflects the additional mechanical demand of operating both keypads and makes the BL2621 appropriate for medium-duty doors that see more frequent use. For very high traffic applications, still consider a purpose-rated heavy duty product - see the Suitable Uses section above.
Monthly: clean both keypad surfaces with a light spray of silicon-based lubricant (such as GT85); remove excess with a soft cloth. Do not use WD-40 or oil-based lubricants on this model. Annually: remove the lock, spray internally through the button holes on both units, and test all buttons and both knobs. Refer to the Borg Servicing Guide (PDF) for full instructions.
If fitting to a narrow aluminium gate frame (50mm x 50mm or similar), the 60mm backset tubular latch included in the box will not align correctly with the gate frame. An extended gate latch (BLS272000 - left and right hand options) is required. Add the correct gate latch to your cart before ordering to avoid delays at install.
If your gate is sheltered from salt air and you are happy to change the code on the bench occasionally, BL2620MGBC gives you the identical knob/knob back-to-back body at a lower price point, in external grade rather than marine grade, with on-the-bench code change instead of Easicode Pro. See which finish and code-change tier is right for your application before deciding.
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 arising from misuse, vandalism, or improper installation. The lock must not be dismantled - doing so will invalidate the warranty.

The short version is above.

For the wider picture on mechanical digital locks generally, see Buyer's Guide Chapter 16 - Mechanical Digital Locks.
Back-to-Back Access and Security
A keypad outside with a free handle inside is only half a lock on many gates - anyone can reach over, reach through the bars, or climb over and simply turn the inside handle to get in, no code needed. Back-to-back closes that gap by requiring the code on both sides. See the full reach-over, reach-through and jump-over problem explained with photos.
Beyond closing the reach-over gap, back-to-back locks give you consistent control over both directions of travel, a genuine deterrent against casual bypass, and one credential to manage instead of two different mechanisms. See the four main benefits in full.
Changing The Code
About 30 seconds once you have the change key in hand - no tools, no removing the lock from the door. Compare that to a standard bench-change Borg lock, which typically takes 5-10 minutes once you are practised, up to 30 minutes the first time. See the full honest-times comparison.
Contact Terry's for a replacement - never force a substitute tool into the * button hole, as this can damage the sacrificial code change spindle. See lost the Easicode Pro change key? for what to do next.
Fit, Handing and Installation
It suits doors up to 85mm thick - the 120mm flat bladed sprung spindle and M4 fixings included cover the great majority of gates and external doors without buying anything extra.
No problem - the lock is reversible on site to suit either a left- or right-hand door or gate, no extra parts needed.
Suitability - Gates, Exit Paths and Alternatives
No - never. Doors on required exit paths must be operable without a key or code in an emergency under the National Construction Code. The BL2621's whole design point is controlled access on both sides, which is the opposite of what an exit path needs. See the plain-terms exit-path rule before specifying this lock on any commercial project.
Not with the latch it ships with - the standard 60mm backset latch is too long for a 50mm x 50mm aluminium stile. You will need the handed 28mm backset left or right hand latch instead. Our gate post and stile sizing guide covers every width you are likely to run into.
If your gate is sheltered from salt air and an occasional bench code change is not a hassle, BL2620MGBC is the identical knob/knob back-to-back body in external grade with on-the-bench code change, at a lower price. If your gate genuinely sees salt air or you will be resetting the code more than rarely, the BL2621 earns its price. See which finish and code-change tier is right for you.
