A door lock is not just about convenience – it is the main protection for your home. However, even the highest-quality mechanism can fail over time. To avoid unpleasant surprises, it’s important to understand the most common causes of lock failure and how to prevent them.
1. Natural wear and tear
Frequent use inevitably wears down the mechanism. Keys may start to stick, and the lock may jam. Regular servicing and lubrication will extend its lifespan.
2. Dirt and moisture
Dust, sand, and moisture inside the lock speed up deterioration, especially in outdoor doors. Protective covers and regular maintenance can help.
3. Incorrect use
Forcing the handle or trying to open the door with the wrong key often damages the cylinder and bolts.
4. Poor installation
Even an expensive lock won’t last if it’s installed incorrectly. Misalignment causes constant friction and jamming.
5. External factors
Vandalism, burglary attempts, and extreme temperature changes can all damage a lock.
If your lock is already sticking or has stopped working, don’t postpone the solution. The best option is to call a professional for door lock repair. An experienced locksmith will quickly restore the mechanism and your home’s security.
