Typical Lock Issues and DIY Repair Solutions
Is your lock feeling stiff or difficult to operate? Or perhaps you’re dealing with broken or stuck keys? Let’s explore
some easy DIY solutions for common lock problems.
Stiff locks
Fixing stiff locks is something we often tackle together. A stiff lock usually means the mechanism inside isn’t moving as freely as it should. This can be due to a buildup of dirt, dust, or even rust.
Using a lubricant is our go-to solution for this common problem. We prefer silicone-based lubes as they don’t

attract more grime. A little lubrication goes a long way in fixing stiff door locks.
We apply just enough lube to make the parts move smoothly again but avoid using too much, which could lead to other issues down the line. Regular maintenance also prevents locks from becoming stiff in the first place.
A quick spray and wipe around the door hinge and strike plate can keep everything working well.
Broken keys
When a key breaks inside the lock, carefully remove any visible fragments using pliers. Utilise a lubricant to loosen the remaining broken piece and gently pull it out. Avoid excessive force to prevent further damage.
Then, carefully inspect the lock for any debris or obstruction and clean it thoroughly before testing with a spare key.
Loose locks
To fix loose locks, tighten the screws on the strike plate with a screwdriver. Ensure all screws are snug and not overly tight to prevent misalignment. If the lock continues to be loose, you may need to replace the strike plate altogether.
This is an important step in securing your home effectively.
Frozen locks
When dealing with frozen locks, using a commercial de-icer or a hairdryer can help melt the ice. Applying gentle heat helps to thaw the lock and prevent damage caused by forceful attempts to unlock it.
Afterward, lubricate the lock to prevent future freezing.
Misaligned door latch
If your door latch isn’t aligning properly, it can cause issues with locking and closing the door securely. To fix this, check the strike plate to see if it’s lining up with the latch when the door is closed.
You may need to adjust the position of the strike plate or make sure that it’s screwed in tightly to ensure proper alignment. This simple adjustment can help in resolving misaligned door latches and improve the overall security of your entryway without requiring professional intervention.
Remember that a misaligned door latch can compromise your home security, so addressing this issue promptly is crucial for maintaining a safe living space. Regularly checking and adjusting these components will also contribute to prolonging the life of your locks and doors while providing peace of mind for you and your family.

Apply lubricant
To fix stiff locks, use a lubricant like graphite or silicone. Apply it to the keyhole, latch, and hinges to ensure smooth operation.
Tighten door hinge screws
To keep your door secure, regularly check and tighten the screws on the hinges. This simple task prevents the door from sagging and ensures proper alignment, which can help prevent potential lock issues caused by misaligned doors.
Regular maintenance helps to enhance overall security in your home or office.
Adjust strike plate
To fix a misaligned door latch, you can adjust the strike plate. This involves loosening its screws and repositioning it slightly to ensure it aligns with the latch. Once aligned, tighten the screws back in place to secure the strike plate and improve the locking mechanism’s functionality.
Remove dirt and dust buildup
To keep locks working smoothly, clean away accumulated dirt and dust by using a soft brush or cloth. Remove the buildup from the keyholes and around the lock mechanism to prevent jams and ensure proper functioning of your locks over time.
Regularly cleaning will help keep your locks in top condition for longer periods.
Regular maintenance keeps our locks functioning efficiently, so we suggest keeping up with this routine cleaning to avoid any potential issues down the track.
Use graphite or silicone
To keep your locks working smoothly, we found that applying graphite or silicone can help prevent them from getting stiff and difficult to use. These lubricants reduce friction and allow the key to turn more easily in the lock, preventing it from jamming.
Regular application of graphite or silicone can extend the life of your locks and ensure they continue to operate without any issues.
When addressing stuck keyholes and resolving frozen locks, using a small amount of graphite powder or silicone spray will make sure your locks stay in top condition while also making it easier for you to unlock your doors when needed.
Address stuck keyholes
Moving on from using graphite or silicone, we can tackle stuck keyholes. This common issue can be frustrating, but there are simple ways to address it without calling a locksmith. First, try gently wiggling the key in the lock to dislodge any debris that might be causing the problem.
If this doesn’t work, you can use a small amount of lubricant such as WD-40 to help loosen the mechanism and get your key moving smoothly again.
Remember not to force the key too hard as this could cause further damage. Instead, apply gentle pressure and patience while trying these solutions for stuck keyholes.
Repair broken keys
Now, let’s focus on repairing broken keys. If you have a broken key, don’t panic. Use a small file to smooth the rough edges of the broken key. After that, you can use tweezers to carefully remove any remaining pieces from the lock.
Then, take a spare key and insert it into the lock. Gently twist and turn it to open the lock. If this doesn’t work, or if there are still pieces inside, it’s best to consult with a locksmith for further assistance in fixing the problem.
Fix loose locks
To start fixing loose locks, first remove the lock cover using a screwdriver. Then, look for any loose screws and tighten them with a screwdriver to stabilise the lock. Apply a small amount of thread-locking adhesive on the screws to prevent loosening in the future.
Finally, reattach the lock cover securely.
Resolve frozen locks
To fix frozen locks, use a hairdryer or warm water to thaw the ice. Avoid using hot water directly on the lock as it can cause damage. Once the ice is melted, apply graphite spray or silicone lubricant to prevent refreezing and ensure smooth operation in the future.
Remember, preventative measures such as regularly lubricating your locks during winter can help avoid this issue.
Troubleshoot worn-out locks
To troubleshoot worn-out locks, inspect the lock mechanism for signs of wear and tear such as rust or corrosion. Consider replacing the lock if it’s extensively worn out or damaged beyond repair.
Look for a new lock that meets your security needs and fits your door structure to ensure proper functioning.
Regularly maintaining and lubricating the lock can prevent it from wearing out prematurely. This includes cleaning, applying lubricant, and tightening any loose components to keep your lock functioning smoothly and extend its lifespan.
Maintain locks regularly
To keep your locks working smoothly, we recommend regular maintenance. This includes cleaning the lock and keyhole with a soft brush to remove dirt and debris. Additionally, applying a small amount of lubricant to the keyway can help prevent sticking and ensure smooth operation.
Regular maintenance will prolong the life of your locks and help you avoid common problems in the future.
Remember, maintaining your locks regularly is crucial for their longevity and efficient performance. By taking these simple steps, you can prevent potential issues that may arise from neglecting your locks.
