To this day, there are still people who do not know the use of this small hole

The current market presents a variety of locks featuring diverse designs, intended for securing gates, doors, cabinets, and other property. Upon closer inspection, one may observe that many locks are equipped with one or two small holes adjacent to the keyhole.
This design consideration arises from the fact that locks are frequently installed in outdoor settings, such as yards or gates, where they are subjected to elements like rain, sunlight, wind, and moisture. Although these locks are typically constructed from materials resistant to rust, such as brass or stainless steel, extended exposure to environmental factors can still lead to oxidation and rust formation. Additionally, rainwater and moisture from dew or humidity can contribute to rust, resulting in locks becoming stiff and challenging to operate.
Without an effective drainage mechanism, locks may become jammed, complicating their use and, in some instances, necessitating lock-breaking methods. To address this concern, manufacturers have incorporated small holes next to the keyhole to facilitate the drainage of water and mitigate rusting. While many users may overlook the purpose of these holes, they play a crucial role in allowing water to escape from the lock.
Consequently, when selecting locks, particularly for areas susceptible to water exposure, such as gate locks or outdoor locks, it is essential to opt for models that include these drainage holes. The absence of such features may result in rainwater accumulating within the lock, leading to rapid rusting. Furthermore, it is advisable to install the lock in a downward position to promote water drainage after rainfall. To avoid the potential of damaging your lock over time, it is important to recognize the significance of these small round holes. Some locks are designed with not just one, but two drainage holes to enhance their functionality.
Each lock is equipped with a small hole that serves as a drainage point. If rainwater collects inside, the lock is likely to rust at an accelerated rate.
