Understanding the Mechanics of a Door Lock Before Applying WD-40: Wd 40 In Door Lock

Before you even think about reaching for that can of WD-40, it’s crucial to understand the intricate dance of components that allow your door to open and close. Knowing how a door lock works is the first step toward effective maintenance and preventing future headaches. This knowledge will not only help you use WD-40 correctly but also give you a better grasp of when professional help might be necessary.

Fundamental Components of a Standard Door Lock

The seemingly simple act of unlocking a door relies on a fascinating interplay of mechanical elements. A standard pin tumbler lock, the most common type found in homes, is a marvel of engineering. Let’s break down its key components:The cylinder is the heart of the lock, the cylindrical housing that contains all the moving parts. It’s the part you insert the key into.The keyway is the opening in the cylinder designed to receive the key.

Its shape is unique to the lock, preventing the insertion of incorrect keys. Pins are the small, precisely sized components that are the lock’s security guardians. They are arranged in pairs: a top pin and a bottom pin for each “shear line” within the cylinder. Springs, typically small coil springs, are essential for pushing the pins down, maintaining their position within the cylinder and the lock body.When the correct key is inserted, it interacts with the pins, lifting them to the correct height.

This alignment allows the cylinder to rotate, which in turn moves the cam (a component that interacts with the latch mechanism), and finally, unlocks the door.Here’s a simplified breakdown:

1. Key Insertion

When you insert your key, its unique cuts push the bottom pins upwards.

2. Pin Alignment

The key’s cuts are designed to lift the bottom pins to a specific height. When all the bottom pins are raised to the correct height, the shear lines between the top and bottom pins align with the shear line of the cylinder.

3. Cylinder Rotation

Once the pins are correctly aligned, the cylinder is free to rotate. This rotation is what allows you to open the door.

4. Cam Movement

The cylinder’s rotation moves the cam, which then interacts with the latch mechanism, retracting the bolt and unlocking the door.Imagine a simple illustration: Picture the cylinder as a circle with several vertical channels. Within each channel are two pins, separated by a shear line. The key, with its unique cuts, acts like a set of levers, lifting the pins until the separation point between each pair aligns perfectly with the shear line of the cylinder.An example of a common malfunction is a sticky lock.

Over time, friction, dust, or even tiny bits of debris can accumulate inside the cylinder, preventing the pins from moving freely. This can make it difficult or impossible to insert the key, turn the key, or retract the bolt. In extreme cases, corrosion from environmental exposure can worsen the situation, creating more friction.

Identifying When WD-40 Might Be a Solution for a Sticky Door Lock

A sticky door lock can be a real nuisance, making it difficult to enter or exit your home or property. While WD-40 is often the go-to solution, it’s crucial to understand when its application is truly warranted and when other underlying issues might be at play. This guide will help you pinpoint the telltale signs that WD-40 might offer a temporary fix and differentiate them from problems requiring more comprehensive attention.

Symptoms Indicating WD-40 Application Might Be Beneficial

Several distinct symptoms can indicate that a door lock could benefit from a dose of WD-40. Recognizing these signs allows for a targeted approach to the problem, potentially saving you time and frustration.

• Difficulty Inserting the Key: If you’re struggling to insert your key into the lock cylinder, it’s a primary indicator of potential issues. This could be due to a buildup of debris, rust, or dried lubricant within the lock’s mechanism, obstructing the key’s path. Imagine trying to thread a needle through a haystack – the key’s path is blocked.
• Resistance When Turning the Key: A key that’s difficult to turn, requiring excessive force, signals a problem. This often points to friction between the lock’s internal components. This friction can be caused by various factors, including the presence of dirt, old grease, or even minor corrosion. The key may feel “stuck” or “gritty” as you attempt to rotate it.
• Key Sticking in the Lock: If the key gets lodged inside the lock and is difficult to remove, it’s a clear sign of internal binding. This could be due to a combination of factors, such as worn-out tumblers, accumulated debris, or a lack of proper lubrication. You might have to jiggle the key or apply considerable force to free it.
• Unusual Noises: Grinding, squeaking, or clicking sounds when operating the lock are telltale signs of friction and potential wear and tear. These noises often accompany the other symptoms, highlighting the need for attention. The sounds are the lock’s way of crying out for help.
• Lock Functionality Varies with Weather: If the lock functions poorly during certain weather conditions, such as cold or humid days, this suggests moisture or temperature-related issues. Cold weather can cause lubricants to thicken, while humidity can promote corrosion. This is like a chameleon adapting to its environment.

Scenarios Where WD-40 Provides a Temporary Fix

WD-40 can offer a quick, albeit temporary, solution in specific scenarios. It’s essential to understand these situations to avoid relying solely on WD-40 when a more permanent fix is required.

For instance, if a lock is only slightly sticky due to minor dust accumulation, WD-40 might temporarily lubricate the mechanism and improve functionality. However, this is akin to applying a bandage to a deep wound. The underlying cause isn’t addressed, and the problem will likely resurface. Consider the case of a lock that becomes stiff during a particularly dry summer.

A small amount of dust has accumulated, and WD-40 might help the key turn. However, the dust is still there, and the problem will return.

Another example involves a lock that has been exposed to light corrosion. WD-40 can help to displace moisture and provide temporary lubrication, but it won’t remove the rust completely or prevent its future formation. Think of WD-40 as a quick fix for a squeaky door hinge – it works for a short while, but eventually, you’ll need a more permanent solution like a proper lubricant.

Furthermore, WD-40 can be useful in dislodging minor debris that has become lodged within the lock’s mechanism. A small piece of dried dirt or a tiny piece of metal can sometimes prevent the key from turning smoothly. WD-40 can help to flush out these particles. However, this is only a temporary solution if the debris is a symptom of a larger problem, such as a worn-out lock or poor maintenance.

Other Potential Causes for a Sticky Door Lock, Wd 40 in door lock

Not all sticky door lock problems are due to a lack of lubrication. Several other factors can contribute to this issue, necessitating alternative solutions.

• Worn or Damaged Lock Components: Over time, the internal components of a lock, such as tumblers and springs, can wear down or become damaged. This can lead to increased friction and difficulty in operation. Replacing the lock cylinder or the entire lockset might be necessary. This is like a car engine with worn pistons – lubrication alone won’t fix the problem.
• Misaligned Door or Strike Plate: If the door or the strike plate (the metal plate on the door frame that the latch engages with) is misaligned, the latch might not engage smoothly. This can cause the door to stick and the key to be difficult to turn. Adjusting the door hinges or repositioning the strike plate can resolve this issue. This is like a door that rubs against the frame – it needs adjustment, not just lubrication.

• Rust or Corrosion: Exposure to moisture can cause rust and corrosion, especially in older locks. Rust can interfere with the lock’s internal mechanisms, leading to stiffness. Rust removal and the application of a rust inhibitor are often required. It’s like having a rusty chain that needs to be treated before it can be used again.
• Accumulation of Dirt and Debris: Dirt, dust, and other debris can accumulate inside the lock, causing friction and hindering the key’s movement. Cleaning the lock with a specialized cleaner or compressed air might be necessary. This is like a clogged vacuum cleaner – it needs to be cleaned to function correctly.
• Improper Key: Using a worn or damaged key, or even a key that is slightly different from the original, can also cause issues. The key might not fit the lock perfectly, leading to resistance. Making a new key or having the lock rekeyed might be necessary. It is like using the wrong key to open a door; it simply won’t work.

• Temperature Fluctuations: Extreme temperature changes can cause metal components to expand or contract, affecting the lock’s functionality. This is more common in older locks. There’s not much you can do about this, but it is important to be aware of the problem.

The Step-by-Step Procedure for Applying WD-40 to a Door Lock

So, your door lock is feeling a bit sluggish, huh? Don’t worry, it happens to the best of us. A little WD-40 can often work wonders, but it’s important to do it right to avoid making things worse. This procedure will guide you through the process, ensuring a smooth operation and protecting your door and surrounding areas. Let’s get started and give that lock some much-needed TLC.

Safety First: Gathering Your Supplies and Preparing the Area

Before you even think about reaching for that can of WD-40, let’s make sure we’re prepared and safe. This step is about protecting yourself and your surroundings.Here’s what you’ll need:

• WD-40 Multi-Use Product: Make sure you have the classic blue and yellow can. Other lubricants might not be as effective or could even damage the lock mechanism.
• Aerosol Straw (Attached to the WD-40 Can): This little red straw is your precision applicator. It allows you to direct the spray exactly where it’s needed.
• Protective Gloves (Optional): If you prefer to keep your hands clean, put on a pair of gloves.
• A Rag or Paper Towels: For wiping up any drips or spills.
• Protective Covering: Like newspaper, cardboard, or a drop cloth to protect the door and surrounding surfaces from overspray.
• Safety Glasses (Recommended): Protecting your eyes is always a good idea.

Now, let’s prepare the area. Spread out your protective covering beneath the door and around the lock. This will catch any overspray and prevent WD-40 from staining your door or the surrounding wall. It’s much easier to clean up a spill from a protective surface than directly from the door itself. Consider taping the protective covering to the doorframe for a more secure barrier.

The Application Process: Lubricating Your Door Lock

Now, for the main event! Here’s how to apply the WD-40 to your door lock, step-by-step.

1. Insert the Key: Insert your key into the lock. This is important because it helps the WD-40 penetrate the lock mechanism effectively.
2. Position the Straw: Attach the red straw to the nozzle of the WD-40 can. This gives you precise control over the spray.
3. Apply the WD-40: Carefully insert the straw into the keyhole. Give the lock a short burst of WD-40, about a one-second spray. Don’t overdo it; a little goes a long way.
4. Work the Key: Remove the key and wipe it clean. Reinsert the key and try to turn it. You might need to jiggle the key a bit or apply some gentle pressure. This helps distribute the WD-40 throughout the lock’s internal components. Repeat the spray and key insertion process several times.

5. Test the Lock: Once you can turn the key smoothly, test the lock a few times to ensure it’s functioning correctly. Check that the bolt extends and retracts easily.
6. Clean Up: Wipe away any excess WD-40 from the lock and the surrounding area. Dispose of the protective covering and any used rags responsibly.

If the key is still difficult to turn after applying WD-40, here are a few things you can try:

• More Application: Sometimes, the lock needs more lubrication. Repeat the WD-40 application process, giving it a few more bursts and working the key.
• Gentle Tapping: Try gently tapping the lock cylinder with the handle of a screwdriver while turning the key. This can help dislodge any debris.
• Consider a Graphite Lubricant: If WD-40 doesn’t work, the lock might need a dry lubricant like graphite. These are available in a spray form and can be found at most hardware stores.
• Seek Professional Help: If all else fails, it’s best to call a locksmith. They have specialized tools and expertise to diagnose and repair more complex lock problems.

Potential Benefits of Using WD-40 on a Door Lock

Applying WD-40 to a door lock can offer several advantages, primarily centered around improved functionality and ease of use. It’s a readily available solution that, when used correctly, can significantly enhance the performance of your locks. Let’s delve into the specific benefits you can expect.

Reducing Friction and Improving Key Operation

WD-40’s primary benefit lies in its ability to act as a lubricant, dramatically reducing friction within the lock mechanism. This is achieved through its formulation, which includes a low-viscosity oil that penetrates and coats the internal components of the lock. This coating creates a slick surface, allowing the tumblers, pins, and other moving parts to glide smoothly against each other.

The consequence of this lubrication is a significantly improved key operation.The key will turn more easily and smoothly. No more struggling or jiggling required. This is especially noticeable in older locks where wear and tear, along with the accumulation of dirt and grime, have increased friction over time. The key’s movement becomes effortless, and the lock operates with a renewed sense of precision.

You’ll likely observe that the key slides in and out of the keyway with greater ease, and the overall experience of locking and unlocking the door becomes far less frustrating.Consider a scenario: A homeowner in a humid coastal region noticed that their front door lock became increasingly difficult to operate, particularly during the rainy season. The key would stick, and considerable force was needed to turn it.

After applying WD-40, the key’s movement became effortless, and the lock operated with a renewed sense of precision. This improvement wasn’t just anecdotal; it was a tangible improvement in the daily experience of accessing their home. The homeowner reported a marked decrease in the time and effort required to unlock the door, and the lock’s performance remained consistently improved for several weeks.

This exemplifies the direct impact of reduced friction on key operation.

Dislodging Debris and Rust

Another significant advantage of WD-40 is its ability to help dislodge small debris and rust that may be hindering the lock’s mechanism. Over time, dust, dirt, and other particulate matter can accumulate inside the lock, interfering with the smooth movement of its internal components. Furthermore, exposure to moisture can lead to rust formation, which binds the parts together, making it hard to turn the key.WD-40 acts as a solvent, penetrating and dissolving these contaminants.

When sprayed into the lock, it can help to flush out the debris, freeing up the moving parts. In cases of light rust, WD-40 can help to loosen the rust particles and prevent further corrosion. This cleaning action is crucial for maintaining the lock’s functionality and preventing more serious damage.Here’s an example: A locksmith was called to a commercial building where several exterior door locks had become completely frozen due to rust.

The locks had been exposed to the elements for years, and the internal mechanisms were severely corroded. While WD-40 alone wasn’t a complete fix in this extreme case, it was the first step in the remediation process. The locksmith applied WD-40 generously to each lock, allowing it to soak in for several minutes. This helped to loosen the rust, making it easier to disassemble the locks and clean the components.

The application of WD-40, combined with other cleaning and lubrication methods, restored functionality to the locks, saving the building owner the expense of complete lock replacements. This situation highlights WD-40’s role in addressing rust-related lock issues.

The Risks and Drawbacks Associated with WD-40 Application in Door Locks

Applying WD-40 to a door lock, while seemingly a quick fix for sticking or squeaky mechanisms, comes with a set of potential downsides that homeowners and users should be aware of. Understanding these risks is crucial for making informed decisions about lock maintenance and preventing future problems. While WD-40 might provide temporary relief, its long-term effects can sometimes be counterproductive.

The Attraction of Dust and Dirt

WD-40, despite its versatility, isn’t specifically designed for the delicate mechanics of a door lock. One of the primary drawbacks of using it is its tendency to attract dust, dirt, and debris. This can ultimately lead to more significant issues down the line.The oily residue left behind by WD-40 acts like a magnet for airborne particles. These particles, ranging from microscopic dust to larger grit, readily adhere to the lubricated surfaces within the lock cylinder and mechanism.

Over time, this accumulation creates a gritty paste that can severely impede the smooth operation of the lock. This buildup can make it harder to insert and turn the key, potentially leading to the key breaking inside the lock or the lock seizing altogether. In humid environments, this mixture can even promote corrosion, further damaging the internal components.Consider the experience of Mr.

Henderson, a homeowner in a coastal town. Initially, WD-40 seemed to solve his sticking front door lock. However, within a few months, the lock became increasingly difficult to use. Upon inspection, a locksmith discovered a thick layer of grime and debris had accumulated inside the lock, completely obstructing the tumblers. The solution involved a complete disassembly, cleaning, and re-lubrication with a specialized lock lubricant, costing Mr.

Henderson both time and money. This case highlights the importance of choosing the right lubricant for the job.Furthermore, the type of environment the lock is exposed to plays a significant role. Locks exposed to outdoor elements, such as rain, wind, and varying temperatures, are more susceptible to attracting dirt and debris. This is especially true in areas with high levels of pollution or dust.

Even indoor locks, particularly those in high-traffic areas or near windows, are not immune to this issue. Regular use, coupled with the buildup of dirt, can exacerbate the problem, making the lock more prone to failure.It’s also worth noting that the long-term impact of WD-40 on certain materials within the lock mechanism is not fully understood. While WD-40 is generally safe for most metals, its interaction with plastics or rubber components can be problematic.

Over time, it might degrade these materials, leading to premature wear and tear. This is another reason why using a lubricant specifically designed for door locks is a better approach, as these products are formulated to be compatible with all the materials typically found in a lock’s construction.
This highlights that WD-40 can lead to:

• Increased friction due to the accumulation of debris.
• Difficulty inserting and turning the key.
• Potential key breakage within the lock.
• Accelerated corrosion, especially in humid environments.
• Premature wear and tear on internal components.

Comparison of Lubricants

Choosing the right lubricant is key for maintaining the smooth operation of your door locks. Here’s a comparison of WD-40 and other specialized lubricants:

Lubricant	Primary Composition	Advantages	Disadvantages
WD-40	Petroleum-based solvents and oils	Readily available, provides short-term lubrication, can displace moisture.	Attracts dirt and dust, short-lasting effect, can damage some materials, not ideal for long-term lock maintenance.
Graphite Lubricant	Dry graphite powder	Does not attract dust, excellent for cold weather, provides long-lasting lubrication.	Can be messy to apply, not suitable for all lock types, may not penetrate deeply into the mechanism.
Silicone Lubricant	Silicone-based compounds	Resistant to water and temperature changes, provides good lubrication, does not attract dust as readily as WD-40.	May not be as effective in removing existing corrosion, can be more expensive than WD-40.
Lock Specific Lubricants (e.g., dry PTFE lubricants)	Formulated specifically for locks, often containing Teflon or similar components	Designed for door locks, excellent penetration, long-lasting lubrication, minimizes dust attraction, safe for various materials.	Often more expensive than WD-40, may require specific application instructions.

Warning: Excessive WD-40 Application

Applying WD-40 excessively to a door lock can create several problems. While a small amount might provide temporary relief, over-application can lead to:

• Increased Dirt Accumulation: More lubricant means more surface area for dust and dirt to adhere to, accelerating the buildup of grime.
• Lock Seizure: The buildup of dirt and the drying of the WD-40 can cause the internal components to stick together, making the lock difficult or impossible to operate.
• Key Damage: Excessive force used to turn a sticky lock can damage the key, leading to breakage or deformation.
• Component Degradation: Over time, the solvents in WD-40 might degrade plastic or rubber components within the lock.

It is essential to use WD-40 sparingly and only as a temporary solution. For long-term lock maintenance, consider using a lubricant specifically designed for door locks.

Alternatives to WD-40 for Lubricating Door Locks and Their Advantages

While WD-40 can sometimes provide a temporary fix for a sticky door lock, it’s not always the best long-term solution. In fact, its properties can sometimes lead to more problems down the line. Fortunately, several excellent alternatives offer superior lubrication and avoid many of WD-40’s potential drawbacks. These alternative lubricants provide tailored solutions for various lock types and environmental conditions, ensuring smoother operation and extended lock lifespan.

Graphite Powder: A Dry Lubricant Solution

Graphite powder, a dry lubricant, is an excellent alternative to WD-40, especially for locks that are exposed to dust and dirt. Unlike liquid lubricants, graphite powder doesn’t attract debris, which can gum up the lock mechanism over time. It’s composed of microscopic flakes of graphite that reduce friction between moving parts.The primary advantage of graphite powder is its resistance to attracting dirt and grime.

This is crucial for outdoor locks or locks in dusty environments. Moreover, graphite powder is effective over a wide temperature range, making it suitable for both hot and cold climates. It’s applied by inserting the nozzle of a specialized container into the keyway and dispensing a small amount. The key is then inserted and removed several times to distribute the powder evenly.

A key benefit of graphite powder is its ability to withstand extreme temperatures, ensuring consistent performance.

Silicone Spray: Moisture Resistance and Versatility

Silicone spray offers a different approach to lubrication, providing excellent moisture resistance and versatility. It’s a synthetic lubricant that creates a thin, protective film on the lock’s internal components. This film reduces friction and repels water, preventing rust and corrosion.The main advantage of silicone spray lies in its water-repelling properties. This makes it ideal for locks exposed to rain, snow, or high humidity.

Silicone spray also has a relatively wide temperature range, similar to graphite powder, and is generally safe for use on various materials, including plastic and rubber components often found in modern lock mechanisms. The application process is similar to that of WD-40, where the spray is applied into the keyway, and the key is used to distribute the lubricant.

Silicone spray is a great choice for outdoor locks due to its excellent moisture resistance.

Teflon-Based Lubricants: Long-Lasting Performance and Low Friction

Teflon-based lubricants, also known as PTFE (polytetrafluoroethylene) lubricants, represent a high-performance option for door lock lubrication. Teflon, commonly known by the brand name Teflon, is a synthetic fluoropolymer with exceptional lubricating properties and extremely low friction. It forms a durable, long-lasting film that reduces wear and tear on the lock’s internal parts.The key advantage of Teflon-based lubricants is their longevity and superior lubricating ability.

They resist high temperatures and provide exceptional wear resistance, making them ideal for high-use locks. Teflon also doesn’t attract dust and dirt to the same extent as some other lubricants, contributing to the lock’s longevity. Application typically involves spraying a small amount into the keyway and working the key in and out.

Teflon-based lubricants offer superior wear resistance, making them suitable for high-use locks.

Choosing the Right Lubricant: A Practical Guide

Choosing the correct lubricant depends on the specific lock type and environmental conditions. Consider the following factors:

• Lock Type: Pin tumbler locks, wafer locks, and disc detainer locks may respond differently to various lubricants. Some lubricants may be more effective or compatible with certain lock designs.
• Environmental Conditions: Locks exposed to moisture require a lubricant with water-repelling properties, such as silicone spray. Locks in dusty environments benefit from dry lubricants like graphite powder.
• Frequency of Use: High-use locks benefit from long-lasting lubricants like Teflon-based products. Less frequently used locks may be adequately lubricated with other options.
• Material Compatibility: Ensure the lubricant is compatible with the lock’s materials, particularly plastic and rubber components. Silicone spray is generally safe for most materials.
• Temperature Range: Consider the temperature extremes the lock will experience. Graphite powder, silicone spray, and Teflon-based lubricants generally perform well across a wide range of temperatures.

Maintaining Door Locks for Optimal Performance and Longevity

Keeping your door locks in tip-top shape isn’t just about preventing sticky situations; it’s about safeguarding your security and extending the lifespan of your locks. Think of it as preventative medicine for your home’s defenses. Regular maintenance can save you the headache (and expense) of lock replacements and potential security breaches. A well-maintained lock operates smoothly, resists wear and tear, and provides reliable protection, ensuring peace of mind for years to come.

Preventative Maintenance Strategies

Proactive care is key to keeping your door locks humming along. Implementing a few simple strategies can significantly reduce the need for frequent lubrication and keep your locks functioning flawlessly. These strategies focus on cleanliness, proper usage, and timely intervention.Regularly cleaning your door locks is a cornerstone of preventative maintenance. Dust, dirt, and debris can accumulate within the lock mechanism, hindering its smooth operation and potentially causing premature wear.

• Protecting from the Elements: If your locks are exposed to the elements, consider installing a door awning or a small cover. This simple addition can shield your locks from rain, snow, and direct sunlight, all of which can accelerate corrosion and damage.
• Proper Key Usage: Avoid forcing keys into the lock. If a key doesn’t turn smoothly, don’t force it. This can damage the internal components of the lock. Instead, try gently wiggling the key or lightly lubricating the key itself with a graphite lubricant.
• Regular Inspection Schedule: Establish a routine inspection schedule. Inspect your locks at least twice a year, or more frequently if you live in a harsh environment. This allows you to identify potential problems early, before they escalate into larger issues.
• Avoid Over-Lubrication: While lubrication is sometimes necessary, avoid overdoing it. Excessive lubricant can attract dirt and grime, leading to a buildup that can clog the lock mechanism. Use lubricants sparingly and follow the manufacturer’s recommendations.
• Addressing Issues Promptly: Don’t ignore any signs of trouble. If you notice a lock sticking, feeling stiff, or making unusual noises, address the issue immediately. Delaying repairs can lead to more significant and costly problems down the road.

Cleaning and Inspecting Door Locks Regularly

Regular cleaning and inspection are essential practices for identifying and addressing potential issues early on. This involves a systematic approach to ensure that your locks are functioning correctly and that any problems are detected before they worsen.Start by gathering the necessary tools: a can of compressed air, a soft-bristled brush (like an old toothbrush), a dry cloth, and a suitable lubricant (such as a graphite lubricant or a dedicated lock lubricant).

1. Exterior Inspection: Begin by visually inspecting the exterior of the lock. Look for any signs of damage, such as rust, corrosion, or physical damage to the lock cylinder or surrounding hardware.
2. Cleaning the Lock Cylinder: Use the compressed air to blow out any loose debris from the keyway and the surrounding areas. Follow this with a soft-bristled brush to remove any remaining dirt or grime.
3. Key Inspection: Examine your keys for any signs of wear or damage. A worn or bent key can make it difficult to operate the lock and can potentially damage the lock mechanism.
4. Operational Check: Insert the key into the lock and turn it several times to ensure smooth operation. Note any sticking, stiffness, or unusual noises.
5. Lubrication (If Necessary): If the lock feels stiff or difficult to turn, apply a small amount of lubricant. Avoid over-lubricating, as this can attract dirt and grime.
6. Interior Inspection (Optional): If you have access to the interior of the lock, you can inspect the internal components for any signs of wear or damage. This might involve removing the lock cylinder (if you’re comfortable doing so) or simply visually inspecting the internal parts.

Early detection is key. A slightly sticky lock that is addressed promptly with a touch of graphite lubricant is far less problematic than a completely seized lock that requires professional intervention. The more regularly you perform this process, the better you will understand how your locks are performing and the sooner you will recognize any changes.
