You’ve probably noticed the small hole on locks , but do you know what it’s for  In reality, this hole serves a very specific purpose . If you didn’t know, here’s your chance to find out . The explanation is below .

The small hole on locks: an essential function

This discreet hole on locks isn’t there by accident. It serves a real purpose.

Let’s say your lock is exposed to rain or placed in a humid environment.

Without this small hole, water could accumulate inside the mechanism, leading to rust and potentially causing the lock to seize up.

Thanks to this hole, water can escape, preventing the internal mechanism from being damaged.

Sometimes, when we try to open a lock, we might be tempted to force it because it seems stuck.

In these situations, this small hole can also be useful for lubricating the mechanism.

Just pour a little oil into this hole, and your lock will work again.

Although this small hole provides an effective solution, weather-resistant locks have recently been created.

These newer models offer better peace of mind, even in the harshest weather conditions.
