Metal locks were commonly used before the advent of fingerprint and smart locks. Today, most households still rely on traditional locks to secure their doors and valuables. Locks are designed to safeguard our possessions, deterring unwanted attention and intrusion. Crafted from metal, locks are typically small yet heavy, ensuring the protection and security of our homes.

Locks are constantly exposed to the elements, be it rain, shine, or dust, as they are used indoors and outdoors. Over time, metal locks, even those made of copper, stainless steel, or inox, are prone to oxidation, resulting in sticking and rusting issues. Additionally, the lubricant within the lock mechanism can deplete, requiring periodic refilling. If left unattended, oxidation and lack of lubrication can lead to significant challenges in opening the lock, sometimes even requiring professional assistance.

The Significance of the Small Hole at the Bottom of a Lock

To address the issues of lubrication and moisture, lock manufacturers introduced a small hole at the bottom of the lock. This hole serves as a drainage outlet, allowing any water that enters the lock to escape, thus reducing the chances of rust and subsequent lock jamming.

While some users may overlook the importance of this small hole, it plays a crucial role in prolonging the life of the lock. For locks exposed to the elements, such as gate locks or those used outdoors, it is essential to opt for locks with this drainage hole, or even better, two holes, to ensure efficient water escape. Without this feature, rainwater can accumulate inside the lock, leading to rapid rusting and potential lock failure.

To expedite water drainage after rainfall, users can tilt the lock downward, allowing water to exit through the hole more rapidly.

Additionally, the small hole at the bottom of the lock serves a dual purpose—it provides an access point for lubricating the lock mechanism when it becomes dry. Instead of applying lubricant through the keyhole, which can be messy and inconvenient, users can directly lubricate the lock through this dedicated hole.

Frequently asked questions

The small hole in a keyhole is known as a ‘keyhole escutcheon’. Its primary purpose is to act as a protective cover, guiding the key into the lock while also preventing debris, dust, and moisture from entering and damaging the locking mechanism.

The escutcheon plays a critical role in maintaining the longevity and functionality of the lock. By keeping out contaminants, it ensures the internal components remain clean and rust-free, reducing friction and wear and tear over time.

In addition to its protective function, the escutcheon also enhances the aesthetic appeal of the keyhole, providing a neat and finished look. It can also be used to conceal any imperfections or gaps around the lock, improving the overall visual presentation.

Keyhole escutcheons can be made from a variety of materials, including metal, plastic, and even wood. Metal escutcheons, such as those made from brass or stainless steel, offer superior durability and corrosion resistance, making them ideal for outdoor applications or in areas with high humidity.

Absolutely! Replacing or upgrading your keyhole escutcheon is a simple and cost-effective way to enhance the appearance of your door hardware. It’s a straightforward DIY project that can instantly add a touch of style or elegance to your home or office.
