Lockwood 8654 Security Door Lock Overview & Applications

Swapping over worn residential or commercial door hardware is straightforward when your replacement part matches standard Australian hole centres and backsets. Our trade counter recommends the Lockwood 8654 Security Door Lock for hinged and sliding aluminium security screen doors, diamond grille barrier doors, and stainless mesh entry doors across Australian homes whenever a job calls for crisp latch action and long-term spare parts support. Direct replacement for Whitco Tasman MK1/MK2, Lockwood 8654, Austral Elegance, and Doric hinged/sliding security screen door locks.

Pair this item with matching hardware in our Screen & Security Door Locks range or check our Euro Lazy-Cam Screen Door Cylinders. On commercial, strata, or rental upgrades, always follow the Standards Australia AS 5039 Security Screen Door & Grille Hardware Standards.

Door Prep & Fitment: 8654 Security Screen Door Lock

Before ordering replacement hardware, run a tape measure over your existing cutout. When checking 8654 security screen door lock on site, the 8654 is built around standard Australian security door mortice cutout (19mm to 20mm x 135mm-195mm aluminium stile pocket) with standard fixing screw centres and auxiliary 3-point rod drive. Matching your existing hole centres and backset lets you swap worn parts cleanly without patching timber.

3-Step Fitting Guide: Reversible Latch Tongue Handing

Follow these three practical steps for reversible latch tongue handing so the mechanism lines up cleanly on the first pass:

1. Check whether your screen door is hinged (Lockwood 8654 / Whitco Tasman MK2) or sliding (Lenlok LSSDL) and reverse the latch tongue handing if required.
2. Slide the mortice chassis into the 19mm-20mm aluminium stile cutout and connect auxiliary top/bottom 3-point locking rods if fitted.
3. Insert your 62mm Euro lazy-cam cylinder with the M5 retaining screw, bolt on the inside and outside lever plates, and adjust the frame striker.

Build Quality & Standards: Euro Lazy Cam Cylinder Compatibility

Lightweight variety-store hardware quickly suffers from handle sag, surface pitting, or sticky latches under Australian sun and coastal air. The genuine 8654 features UV-stabilised powder-coated zinc alloy handles with a corrosion-resistant steel mortice body and internal privacy snib lever tested to AS 4145.2. Engineered around Euro lazy cam cylinder compatibility, every internal spring and load-bearing surface is built to handle heavy daily foot traffic.

For single-key convenience across your property, the 8654 includes a 5-pin C4 cylinder with DualSelect two-stage key locking and internal snib control.
