Borg Mechanical-Digital 3430 Marine Back-to-Back EasiCode - Key Override - Code Lockout

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.

The lock is finished in MG Pro black marine external grade coating and tested to 1,000 hours of continuous salt spray. It uses the forend fixing system, suits gate profiles from 40mm to 60mm square on standard fixings, and is fully mechanical with no batteries or wiring. The euro cylinder is not supplied and must be ordered separately.

Estimated Warehouse Dispatch
Usually same day if ordered before 11am AEST (excluding weekends and Qld public holidays)

Designed for Metal Box-Section Gate Frames – Not a Door Lock
The BL3430DKOMGPROECP is a purpose-built gate lock. It uses 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.

Marine Grade Pro – 1,000 Hour Salt Spray Tested
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. Suitable for coastal, beachside, canal-front, and pool gate applications.

1 Year Guarantee Against Faulty Materials and Workmanship

Easicode Pro – On-Gate Code Change
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.

Back-to-Back Keypads – Code Required Both Sides
This model has a full keypad unit on both the outside and inside of the gate. The same PIN code operates both keypads. Entering the code is required to enter and exit — there is no free egress from inside.

Key Override & Code Lockout / Deadbolt Function
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 the gate from being opened via keypad code until the key releases it.

Fully Mechanical – No Batteries Required
Entirely mechanical. No power source, no wiring, and no battery maintenance at any point.

Single PIN Code Only
Accepts one active PIN code at a time.

Code Required to Exit – No Free Egress from Inside
Unlike single-sided models, 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.
