Borg BL3430 MG Pro ECP Mechanical Digital Gate Lock – Back-to-Back – Key Override & Code Lockout – Marine Grade Pro – Black
The Borg BL3430DKOMGPROECP is the flagship model in the BL3400 / BL3430 gate lock family – combining Marine Grade Pro construction, Easicode Pro on-gate code change, back-to-back keypads, and a euro cylinder key override with code lockout / deadbolt function. Using the key deadlocks the latch bolt and disables the keypad, preventing gate operation by code until the key releases it.
Finished in MG Pro black marine external grade coating and tested to 1,000 hours of continuous salt spray. Forend fixing system, suits gate profiles from 40mm to 60mm square. Fully mechanical, no batteries. Euro cylinder not supplied – must be ordered separately.
Usually same day if ordered before 11am AEST (excluding weekends and Qld public holidays)
These locks use a forend fixing system that clamps directly onto the gate post — no mortice cutting or door-edge drilling required. Designed for square aluminium or steel gate posts from 40–60mm. For profiles wider than 60mm, an optional XL latchbolt extension is available separately.
Finished in MG Pro black marine external grade coating with marine grade stainless steel internal components. Tested to 1,000 continuous hours of salt spray exposure.
Borg warrants corrosion resistance for 12 months from date of sale under specified conditions.
The PIN code can be changed while the lock is installed on the gate using the included code change key. No lock removal, no tools required.
Both sides of the gate have a full keypad. The same PIN code operates both keypads. Entering the code is required to enter and exit — there is no free egress from inside.
This model includes a euro cylinder key override (cylinder not supplied). Using the key: (1) provides emergency key access, and (2) activates a code lockout — the key deadlocks the latch bolt, preventing gate operation by keypad code until the key releases it.
The inside keypad requires the correct PIN before the lever operates. Confirm this suits your application and complies with any applicable fire egress or building regulations before purchasing.
Entirely mechanical. No power source, no wiring, and no battery maintenance at any point.
Accepts one active PIN code at a time.

Frequently Asked Questions
How does the forend fixing system work?
The lock body sits on the face of the gate frame and clamps onto the gate post using telescopic fixing screws supplied. No drilling through the gate edge or mortice pocket is required. The latchbolt projects from the lock body and engages a strike on the gate post or adjacent frame. The latch projection is adjustable from 65mm to 80mm to suit different gate frame widths. For gate posts wider than 60mm, an optional XL latchbolt extension is available separately.
How does the DKO key override and code lockout work?
DKO stands for "Double Key Override." The euro cylinder (not supplied) fits into the lock body. Turning the key in one direction unlocks the gate by key without entering the code. Turning it further activates the code lockout / deadbolt: the latchbolt is deadlocked and the keypad is disabled — code entry will not open the gate until the key is turned to release the deadlock. This allows an authorised keyholder to fully lock down gate access. Source a standard euro profile cylinder from your locksmith, confirming the correct length for your gate post.
How do I change the PIN code with ECP?
With the gate open, enter the current code. Insert the code change key over the Φ button, rotate 90° clockwise and hold. Press C to clear, enter new digits, confirm all digits, then release and remove the key. Press C or rotate the lever to finalise. Test at least 5 times before closing the gate. The code is non-sequential — buttons can be pressed in any order.
My gate post is wider than 60mm — what do I do?
An optional XL latchbolt extension is available separately, extending the maximum gate post width to 120mm. Contact us or search "Borg XL latchbolt" to find the correct accessory for your gate profile. Always confirm the correct gate post width before ordering.
Is this lock suitable for a pool gate?
The lock's spring-loaded latch is self-latching on gate close, which aligns with pool safety self-latching requirements. However, confirm all pool gate safety compliance requirements with a licensed pool safety inspector before installation, as compliance encompasses more than just the lock (gate height, clearances, overall system). For the Queensland Pool Safety Standard specifically, confirm with your local inspector.
Additional Information
The euro cylinder must be sourced separately. Contact a locksmith to supply and fit a standard euro profile cylinder in the correct length for your gate post.
Monthly: apply a light spray of silicon-based lubricant (GT85 or equivalent) to both keypad and lever surfaces; wipe off excess. Annually: remove and service internally. Refer to the Borg Servicing Guide PDF.
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.
