5 Lock Maintenance Tips to Survive Melbourne's Climate Shifts

Melbourne's climate is notoriously unpredictable. The swift shift from dry 38°C summer heat to damp, freezing winter downpours places physical stress on your property's entry points.

Here are 5 simple maintenance tips to keep your locks operating smoothly:

1. Realign Striking Plates When timber door frames swell during winter rain, the deadbolt or latch may no longer line up with the hole in the strike plate. Do not force the key to turn, as it can bend or snap. Instead, adjust the position of the strike plate on the frame slightly.

2. Use Graphite or Dry Silicone Lubricants Never spray standard WD-40 or grease directly into key slots. While it provides short-term lubrication, grease is sticky and collects dust, grit, and metallic dust, forming a thick paste that eventually seizes the tumbler pins. Instead, use dry powdered graphite or dry silicone sprays.

3. Check and Tighten Hinges A heavy solid timber door can sag over time if the hinge screws loosen. Even a millimeter of sag will throw the deadlock alignment off, stressing the lock. Check and tighten hinge screws annually.

4. Wipe Down Coastal Bayside Locks If you live in St Kilda, Brighton, or Altona, salty coastal sea mist will cause outer finishes to tarnish and internally rust. Wipe down lock faces weekly with a clean microfiber cloth to prevent salt encrustation.

5. Replace Remote Batteries Annually For automotive fobs and digital door locks, replace batteries annually before they die. Cold winter mornings reduce battery voltage, which is when cheap cells often fail.
