Therefore, when purchasing locks, especially for places prone to water exposure such as gate locks or outdoor locks, it’s important to choose ones with these drainage holes. Without them, rainwater may accumulate inside the lock, causing it to rust quickly. Moreover, when using the lock, it’s a good idea to position it downward to allow water to drain out after each rain.

If you don’t want to end up breaking your lock after some time, remember the function of these small round holes. Some locks come with not just one but two holes for draining water.

Each lock has a small hole next to it. Their function is to act as a drainage area. If rainwater stagnates inside, the lock will rust quickly.
