Simple Lock Maintenance Habits to Avoid Costly Breakdowns

A faulty lock is often a result of simple wear and tear that could have been prevented with basic, proactive maintenance. By dedicating a few minutes a year to your locks, you can drastically increase their lifespan, save money on emergency call-outs, and ensure your home remains secure. Here are the three simple habits every Dorset homeowner should adopt.

Habit 1: Routine Lubrication (The Right Way) The most common cause of lock failure is friction and corrosion.

• What to Use: A silicone-based spray or graphite powder is recommended for all types of locks (uPVC, timber, metal).

• What to Avoid: Never use oil-based products that attract dust and dirt, as this will lead to a sticky, seized lock mechanism.

• Frequency: Lubricate external locks and uPVC mechanisms at least once per year, or every 3–6 months if you live near the coast to combat salt air corrosion.

  
  

Habit 2: Don't Force a Sticking Key

If your key is stiff or sticking, stop immediately. Forcing the key is the number one cause of snapped keys and broken uPVC gearboxes. The key is sticking because the pins are misaligned (needs lubrication) or the door is dropped (needs alignment). If it's stiff, gently wiggle, lubricate, or call a professional.

Safety Tip: Always ensure your uPVC door is locked with the key, not just lifted on the handle, when you leave the house.

Habit 3: Check and Tighten Door Furniture

Worn-out door furniture (handles, hinges, escutcheons) can put damaging stress on the internal lock components.

• Handles: If the handle is loose, the spindle may be applying inconsistent force to the lock. Tighten the visible screws, but do not overtighten, which can compress the lock mechanism.

• Check the Frame: Look for paint damage or excessive wear around the strike plate on the door frame. This indicates the door is rubbing or misaligned and needs adjustment before it stresses the lock.
