How to Remove a Broken Key from a Lock: A Complete Step-by-Step Guide
Broken keys inside locks are a problem that, while not very common, can be extremely frustrating when it happens. This issue not only puts access to your home or workplace at risk, but can also lead to additional costs if it is not handled properly. Fortunately, removing a broken key is not an impossible task, and there are several methods—both DIY and professional—that can help resolve the problem. In this article, we explain how to do it effectively and safely.
Common Causes of Broken Keys
Before going into the solutions, it is important to understand the possible reasons why a key may break inside a lock. This will help you be better prepared and may even prevent it from happening again in the future.
Worn key:
Over time, keys wear down due to repeated use. This wear can make the key more fragile, increasing the risk of it breaking when opening or closing a door.
Forcing the lock:
If a lock is jammed or not working properly, many people try to force the key, which can cause it to snap inside the lock.
Problems with the lock:
Sometimes the issue is not the key, but the lock itself. A damaged lock can cause the key to get stuck or break when you try to turn it.
Use of low-quality keys:
Poor-quality or improperly cut keys are more likely to break, especially when excessive force is applied.
Step 1: Assess the Situation of the Broken Key
Before attempting any technique to remove the broken key, you should evaluate the situation. Is the key completely inside the lock, or is part of it sticking out? This will determine which methods you can use.
If the key is sticking out:
If a small part of the key is protruding from the lock, it will be easier to remove. You can try using pliers or a specific extraction tool.
If the key is completely inside:
If the key is fully inside the lock and not visible, you will need specialised tools or more advanced methods.
Step 2: Lubricate the Lock
A key step before trying to extract the broken key is to apply lubricant to the lock. This helps the key slide out more easily and reduces friction, making extraction more efficient.
You can use products such as WD-40 or sprays specifically designed for locks. Simply spray a small amount directly into the lock and let it sit for a few minutes. This step is essential to avoid damaging the lock or making the key jam even further.
Step 3: DIY Methods to Remove the Key
A. Using Precision Pliers
If part of the broken key is sticking out of the lock, you can try using precision pliers to grip the broken piece and gently pull it out. Fine-tip pliers are ideal for this task, as they provide a more secure grip.
How to do it:
- Insert the pliers around the visible part of the broken key.
- Pull gently and steadily outward, avoiding sudden movements that could further damage the lock.
B. The Wire Technique
If you do not have precision pliers, you can try using a thin piece of wire. This method is especially useful if the broken key is fairly deep inside the lock but can still be hooked.
How to do it:
- Cut a piece of wire and bend it into a hook shape.
- Insert the hook into the lock and try to catch the broken part of the key.
- Once hooked, gently pull it out.
C. Using a Needle or Small Screwdriver
If the wire method does not work, you can try using a needle or a small screwdriver. Carefully insert it into the keyway and try to push the broken piece outward, or move it until you can hook it.
Step 4: Specialised Tools for Key Extraction
If DIY methods do not work, broken key extractors are available. These tools are specifically designed for this situation and are highly effective.
Key extractor:
A key extractor is a thin, flexible tool that can be inserted into the lock. Its design allows it to hook onto the broken piece of the key and remove it easily.
How to use it:
- Insert the key extractor into the lock, aligning it with the broken key.
- Turn the extractor slightly to the left to hook onto the broken key.
- Once the extractor has a grip on the key, gently pull it out.
If you do not have a key extractor, many hardware stores or specialised tool shops sell them at a reasonable price.
Step 5: What to Do If You Cannot Remove the Key
If none of the above methods work and the key remains stuck in the lock, the best option is to call a professional locksmith. Locksmiths have specialised tools and techniques to extract broken keys without damaging the lock.
Why call a locksmith:
- They have the experience and tools needed to handle difficult locks without causing damage.
- They can determine whether the lock itself is damaged and offer options for repair or replacement.
- If the broken key is too deep or cannot be easily extracted, a locksmith can remove it quickly and safely.
Step 6: Preventing the Key from Breaking Again
Once the broken key issue has been resolved, it is important to take steps to prevent it from happening again in the future.
Check your keys regularly:
Inspect your keys to make sure they are not worn or damaged. If you notice cracks or signs of wear, replace the key before it breaks.
Lubricate the lock:
Regular lock maintenance helps the key turn more smoothly. Lubricate locks every six months or whenever you notice the key starting to stick.
Avoid forcing locks:
If a lock does not turn easily, do not force it. Instead, apply lubricant and check for any obstruction. If the problem persists, call a locksmith to repair the lock.
Conclusion
Removing a broken key from a lock can be challenging, but with the right tools and techniques, it can be done effectively and safely. Always remember to assess the situation carefully before taking drastic measures. If you do not feel comfortable performing the procedure yourself, do not hesitate to contact a professional locksmith who can help resolve the issue without causing further damage. With a bit of preventive maintenance, you can also reduce the likelihood of this problem occurring again in the future.
