- Pay attention - If you notice it starts working differently, or starts making more noise than usual it may be a sign its in need of a service.
What can you do to keep your locks working optimally?
Luckily, keeping your locks in top-notch condition isn't rocket science—it involves a series of simple yet effective steps. Here's what you can do:
- Cleaning is key: Regularly wipe down lock mechanisms with a mild soap solution, making sure to dry them thoroughly to prevent moisture damage. Use an air spray can with a straw to spray into the lock which should remove any loose debris without causing any damage to the lock
- Lubrication is paramount: A squirt of graphite powder or silicone-based lubricant will ensure smooth function; steer clear of oil-based alternatives that can attract grime. Tightening also does wonders: Address any loose screws or hardware to keep the lock aligned and operational.
- Duplication demands precision: When making duplicate keys, choose a reputable locksmith to maintain the integrity of the lock.
- Professional servicing is prudent: Annual check-ups by an expert are invaluable for complex systems or frequently used doors. Call a local locksmith who will be able to assist in lock repairs and servicing.
1 - Regularly clean the locks
The process of cleaning your locks should be systematic and mindful of the lock's materials:
- Gentle cleaning is crucial: Use a soft cloth and avoid harsh chemicals to prevent damage.
- Detailed dusting: Employ a toothbrush or similar tool to nudge debris out of nooks and crannies.
- Thorough drying: Ensure that no moisture is left behind as it can lead to rust or damage internal components.
- Don’t Overclean Locks
- When it comes to locks, more cleaning isn't always better:
- Limit liquid cleaners: These can seep into the internals, promoting rust.
- Opt for dusting: A soft, dry cloth is generally sufficient for routine maintenance.
- Sparingly lubricate: Choose suitable products to keep the lock functioning with ease, without inducing a buildup.
- Be gentle with the locks
- Your approach to maintaining your locks should combine firm action with a gentle hand.
- Use appropriate cleaners and lubricants: Avoid harsh agents and heavy oils that can harm more than help.
- Screw-tightening: This helps to secure lock plates and handle fixtures.
- Precision-made duplicates: Only perfect copies will suffice to prevent unnecessary wear.
2 - How often should I lubricate my locks?
- Lock lubrication should become a part of your regular household maintenance routine:
- Follow a schedule: Every half a year to annually, depending on frequency of use.
- Adjust for environment: If your home faces harsh conditions, lubricate accordingly.
