As a supplier of Split Handle Locks, I often receive inquiries from customers about the best lubricants to use for these locks. Proper lubrication is crucial for the smooth operation and longevity of split handle locks. In this blog, I will discuss the different types of lubricants suitable for split handle locks, their benefits, and how to apply them correctly.
Why Lubricate Split Handle Locks?
Split handle locks are commonly used on exterior doors, and they are exposed to various environmental factors such as moisture, dust, and dirt. Over time, these elements can cause the lock components to wear out, leading to stiffness, difficulty in turning the key, and even lock failure. Lubrication helps to reduce friction between the moving parts of the lock, preventing wear and tear and ensuring smooth operation. It also protects the lock from corrosion and rust, extending its lifespan.
Types of Lubricants for Split Handle Locks
There are several types of lubricants available on the market, each with its own advantages and disadvantages. Here are some of the most common types of lubricants suitable for split handle locks:
Graphite Lubricant
Graphite lubricant is a dry lubricant that is ideal for use in locks. It is made from fine graphite powder, which provides excellent lubrication without attracting dust and dirt. Graphite lubricant is also resistant to moisture, making it suitable for use in outdoor locks. It is easy to apply and can be used on both the keyway and the lock mechanism.
Silicone Lubricant
Silicone lubricant is a popular choice for lubricating split handle locks. It is a clear, odorless, and non-toxic lubricant that provides long-lasting lubrication. Silicone lubricant is also resistant to water, heat, and cold, making it suitable for use in a variety of environments. It can be used on both the keyway and the lock mechanism, and it helps to prevent corrosion and rust.
WD-40
WD-40 is a multi-purpose lubricant that is commonly used for a variety of applications, including lubricating locks. It is a petroleum-based lubricant that provides excellent lubrication and corrosion protection. However, WD-40 is not recommended for use in locks on a regular basis, as it can attract dust and dirt, which can cause the lock to become clogged. It is best used as a temporary solution to free up a stuck lock.
Teflon Lubricant
Teflon lubricant is a high-performance lubricant that is made from polytetrafluoroethylene (PTFE). It provides excellent lubrication and is resistant to heat, cold, and chemicals. Teflon lubricant is also non-stick, which helps to prevent dirt and debris from sticking to the lock components. It can be used on both the keyway and the lock mechanism, and it helps to extend the lifespan of the lock.
How to Apply Lubricant to a Split Handle Lock
Applying lubricant to a split handle lock is a simple process that can be done in a few easy steps. Here's how:
Step 1: Clean the Lock
Before applying lubricant to the lock, it is important to clean it thoroughly to remove any dirt, dust, or debris. You can use a clean cloth or a small brush to clean the keyway and the lock mechanism. Make sure to remove any visible dirt or debris before proceeding.
Step 2: Choose the Right Lubricant
As discussed earlier, there are several types of lubricants available for split handle locks. Choose the lubricant that is best suited for your lock and the environment in which it is used.
Step 3: Apply the Lubricant
Once you have chosen the lubricant, apply it to the keyway and the lock mechanism. You can use a small applicator or a spray can to apply the lubricant. Make sure to apply the lubricant evenly and avoid over-applying it.
Step 4: Work the Lock
After applying the lubricant, insert the key into the lock and turn it several times to work the lubricant into the lock mechanism. This will help to distribute the lubricant evenly and ensure smooth operation.
Step 5: Wipe off Excess Lubricant
Once you have worked the lock, use a clean cloth to wipe off any excess lubricant from the keyway and the lock mechanism. This will help to prevent dirt and debris from sticking to the lock components.

Proper lubrication is essential for the smooth operation and longevity of split handle locks. By choosing the right lubricant and applying it correctly, you can ensure that your locks operate smoothly and efficiently for years to come.
