A door lock experiences daily stress, as it is responsible for ensuring the safety and comfort of your home. Over time, even a reliable mechanism can start to malfunction if it’s not properly maintained. A few simple habits can significantly extend the life of your lock and help you avoid costly repairs.
Regularly check the condition of the lock and the keys. If you notice stiffness, squeaking, or jamming when turning the key, it’s a clear sign that dust or worn parts have accumulated inside the mechanism. In such cases, it’s best to clean it or call a specialist for preventive maintenance.
Avoid using universal lubricants like WD-40. They may temporarily improve performance but quickly attract dust and dirt. Instead, use silicone-based or graphite lubricants designed specifically for locks.
Make sure your door is properly aligned. Even a slight misalignment can cause the lock to operate under pressure and eventually jam. Check the hinges regularly and adjust the door’s position if needed.
During winter, protect the lock from moisture and freezing. Water entering the keyhole and freezing can deform internal components. Use protective covers and avoid inserting wet keys into the cylinder.
If your lock has started to work tightly or the key has become deformed, don’t postpone calling professionals for door lock repair. Professional maintenance and timely service will help you avoid expensive replacements and keep your door secure for years to come.
