Steps For Regular Maintenance Of Home Locks

Last updated: September 2, 2023


Ensuring the security of your home is paramount, and one of the primary ways to achieve this is through the proper maintenance of home locks. According to the Insurance Information Institute, homeowners who do not maintain their home security systems, including locks, may see their insurance premiums rise or their policy become void. Regular maintenance not only ensures that your locks function optimally but also extends their lifespan, saving you the cost and hassle of frequent replacements. 

In this comprehensive guide, we’ll delve into the essential steps for regular maintenance of home locks.

Understanding The Importance Of Lock Maintenance

Locks are the first line of defense against unauthorized access to your home. Over time, due to wear and tear, locks can become less effective. Regular maintenance ensures that they remain in top condition, offering you the peace of mind you deserve.

Important Steps For Regular Maintenance Of Home Locks

The American Association of Retired Persons (AARP) reports that 67% of burglaries could be prevented with proper home security, including well-maintained locks. This highlights the importance of regular lock maintenance in preventing break-ins. To ensure your home locks are in perfect working order, it is important to follow certain key steps:

Cleaning Your Locks

Dirt and grime can accumulate in your locks over time, affecting their functionality.

Materials Needed:

  • Soft cloth

  • Mild soap

  • Warm water

Basic Steps For Maintenance:

  • Dampen the cloth with a mixture of mild soap and warm water.

  • Wipe the exterior of the lock gently, ensuring you don’t force water into the keyhole.

  • Dry with a clean cloth.

Checking For Wear And Tear

Regularly inspect your locks for signs of wear and tear. If you notice any rust or if the lock becomes difficult to operate, it might be time for a replacement. 

Lubricating The Locks

Another crucial step in maintaining home locks is to lubricate them regularly. This can be done using a graphite-based lubricant, which can be sprayed directly into the keyhole. Lubricating the locks not only ensures their smooth operation but also helps to prevent the accumulation of dust and debris that could potentially jam the lock. Moreover, during cold weather, lubrication can help to prevent the lock from freezing. However, it’s essential to avoid using oil-based lubricants as they can attract dirt and eventually cause the lock to stick.

Cleaning The Locks

Periodically, you should clean your locks to get rid of dirt and grime that could affect their functionality. You can use a mild detergent and a soft cloth to clean the exterior part of the lock. For the interior, use a can of compressed air to blow out any dust or debris. If your lock is particularly dirty, you might want to consider disassembling it for a thorough cleaning. However, you should only do this if you are confident in your ability to reassemble it correctly. 

Rekeying Or Changing Locks

If your keys have been lost or stolen, or you’ve moved into a new home, it’s a good idea to rekey or change your locks. This will ensure that only you and those you trust have access to your home. A professional locksmith can easily rekey your locks, changing the internal workings so that they respond to a new key.

Regular Testing

Just like any other security measure, locks should be tested on a regular basis to ensure they are working correctly. Try locking and unlocking each door in your house to check if there are any issues. If a lock isn’t functioning as it should, it’s best to get it fixed or replaced as soon as possible.

Updating Old Lock Systems

While maintenance is essential, it’s equally crucial to recognize when it’s time to upgrade. Modern lock systems offer enhanced security features that older models might lack. Updating old lock systems not only improves the level of security but also adds convenience. Modern locks often incorporate technology, allowing for keyless entry, remote access, and even integration with home security systems. 

Professional Inspection

At least once a year, have a professional locksmith inspect your locks. They can identify potential issues and offer solutions before they escalate.

Key Maintenance

Your lock is only as good as the key you use. Ensure your keys are free from rust and damage. If they’re worn out, get them replaced. Also, it is advisable to regularly lubricate your keys to prevent them from getting stuck or jammed in the lock. This can be done by applying a small amount of graphite powder or a specially designed lock lubricant to your key and then inserting it in and out of the lock several times. Avoid using oil or grease, as they can clog the lock mechanism over time. Additionally, never force your key to turn in the lock, as it may cause it to break. If your key is not turning smoothly, it could be a sign that your lock needs servicing or replacing. Always have a spare key in case of emergencies, but ensure it’s kept in a secure and accessible place.

Avoid Using Excessive Force

When unlocking your door, use gentle, consistent pressure. Using excessive force can damage both the key and the lock.

Checking For Strike Plates Misalignment 

The strike plate serves as the unsung hero of your door lock system. It’s the metal plate affixed to the door frame, designed to receive and hold the bolt or latch in place. Its robustness and alignment are critical for the smooth operation of the lock and the security of the door. Misalignment can occur due to various reasons, including house settling, frequent use, or even temperature changes. Symptoms of a misaligned strike plate include:

  • Difficulty turning the key when locking or unlocking.

  • The door not sitting flush when closed.

  • Visible gaps between the strike plate and the latch.

Regularly inspect the alignment by slowly closing the door and observing how the latch meets the strike plate.

Adjustment/Replacement Of Strike Plates

If misalignment is detected:

  • Loosen the screws slightly and adjust the plate’s position.

  • Tighten the screws once the optimal position is found.

  • If the misalignment persists or if the strike plate shows signs of wear and tear, consider replacing it with a high-security strike plate, which offers enhanced protection.

Cleaning The Locking Mechanism

The locking mechanism is the core of your security system. Ensuring its optimal functionality is vital for your home’s safety.

Lubricating The Lock Mechanism

Lubrication is crucial for the smooth operation of your locks.

Materials Needed:

Graphite powder or silicone-based lubricant

Steps For Cleaning The Lock With A Soft Cloth

Over time, external elements can tarnish the lock’s appearance.

  • Dampen a soft cloth with a mixture of mild soap and water.

  • Gently wipe the lock’s exterior, ensuring no water enters the keyhole.

  • Dry thoroughly with a clean cloth.

Applying Dry Lubricants Or Graphite Powder

Dry lubricants are preferred for locks as they don’t attract dirt:

  • Insert the lubricant or graphite powder into the keyhole.

  • Turn the key several times to distribute it evenly inside the mechanism.

Applying Oil-Based Lubricants With Care

While effective, oil-based lubricants can attract grime:

  • Apply sparingly to avoid buildup.

  • Wipe away excess lubricant from the lock’s exterior.

Applying Protective Coatings To The Lock Mechanism

To prevent corrosion and extend the lock’s lifespan:

  • Choose a suitable anti-rust spray or protective coating.

  • Apply as directed, ensuring even coverage.

Frequently Asked Questions

For optimal performance, it’s recommended to lubricate your lock mechanism at least once a year. However, if you notice any grinding or resistance when turning the key, it might be time for immediate lubrication.

Can I use any oil-based lubricant on my locks?

While many oil-based lubricants can work, it’s best to use those specifically designed for locks. These lubricants are formulated to provide smooth operation without attracting excessive dirt or grime.

What are the signs that my locking mechanism needs maintenance?

Difficulty in turning the key, a squeaky sound during operation, or visible rust are clear indicators that your locking mechanism requires maintenance.

How do protective coatings help in lock maintenance?
