How to Remove a Broken Key from a Lock: Easy DIY Hacks Using Household Items

There’s nothing more frustrating than trying to unlock a door only to discover that the key has snapped off inside the lock. Whether you’re dealing with a broken car key or a home door key, removing a broken key from a lock can feel like an impossible task. But don’t worry! You don’t need to hire a locksmith right away. With a few simple household items, you can successfully extract that broken key and get back to your day.
In this guide, we’ll show you how to remove a broken key using everyday household items like super glue, hot glue, and other tools you likely already have in your home. Read on for practical, budget-friendly solutions!

What You’ll Need: 

1. Super glue or hot glue
2. Needle-nose pliers or tweezers
3. Paperclip or bobby pin
4. Penetrating oil (WD-40, optional but helpful)
5. Duct tape (optional, for better grip)
6. Rubber gloves (optional, for extra grip)

Step 1: Lubricate the Lock for Easier Removal (Optional)

Before diving into the removal process, consider using some penetrating oil like WD-40 to lubricate the lock mechanism. This step helps loosen any debris, rust, or grime inside the lock, making the broken key easier to remove.

How to do it:

1. Spray a small amount of penetrating oil into the keyhole.
2. Let the oil sit for about 1-2 minutes to loosen up any buildup and help ease the key out.
3. Make sure you wipe away any excess oil to avoid dripping into unwanted areas.

Step 2: Try Using Super Glue to Extract the Broken Key

One of the most effective methods for removing a broken key is to use super glue. This hack involves bonding a small object (such as a toothpick or matchstick) to the broken part of the key and gently pulling it out. It may sound simple, but this technique can work wonders when done carefully.

How to do it:

1. Apply Super Glue: Dab a small amount of super glue onto the tip of a toothpick, matchstick, or even a small piece of plastic. The goal is to attach this object to the protruding part of the key (if any is sticking out).
2. Press Against the Broken Key: Gently press the glued object against the broken key piece. Be sure not to apply glue directly to the lock mechanism, just the key.
3. Wait for the Glue to Dry: Allow the glue to set for about 1-2 minutes. Don’t rush; ensure the bond is solid before pulling.
4. Pull the Key: Carefully and gently pull the object attached to the key once the glue has dried. Wiggle it slightly as you pull to free the key from the lock.

Tip: If you accidentally get glue in the lock, wipe it off immediately before it dries to prevent damage.

Step 3: Use Hot Glue for Stubborn Pieces

If the super glue method doesn’t work or the key is deeply stuck, you can try using hot glue. Hot glue is thicker and creates a stronger bond, which is helpful if you have little to no key sticking out.

How to do it:

1. Heat up a hot glue gun and squeeze out a small amount of glue onto a toothpick or skewer.
2. Quickly press the glued object against the broken key piece inside the lock.
3. Allow the hot glue to cool and harden for about 1-2 minutes.
4. Gently pull the toothpick or skewer while wiggling it back and forth. The hot glue should have bonded well enough to pull the key out.

Step 4: Use Pliers or Tweezers to Grip and Pull

If there is any part of the key sticking out, needle-nose pliers or tweezers can be your best friend in this process. These tools allow you to get a firm grip on the broken key, so you can pull it out with precision.

How to do it:

1. Grab your pliers or tweezers and gently grasp the protruding part of the broken key.
2. Slowly and carefully pull the key out, wiggling it side to side as needed to free it from the lock.
3. If the key won’t budge, don’t force it! You can try other methods or lubricate it again with penetrating oil.

Step 5: Use a Paperclip or Bobby Pin (DIY Key Extractor)

If the broken key is deeply lodged inside the lock and there’s no part sticking out to grab, you can make your own DIY key extractor using a paperclip or bobby pin.

How to do it: 

Unwind a paperclip or straighten a bobby pin to form a small hook.

Carefully insert the hooked end into the keyhole and try to catch the edge of the broken key.
Once you hook the key, slowly pull it out. It may take a few tries, so be patient!

Step 6: Use Duct Tape for a Better Grip

If you’re having trouble gripping the broken key, duct tape can provide extra traction. This simple trick can give you the added grip needed to pull out the key.

How to do it:

Cut a small piece of duct tape (sticky side up).

Press the tape onto the end of the broken key that is protruding.
Gently pull on the tape while wiggling it back and forth to remove the key.

Step 7: If All Else Fails, Call a Locksmith

1. If you’ve tried all these household hacks and the key is still stuck, it’s time to call in the experts. A professional locksmith will have specialized tools and experience to remove the key without causing damage to the lock.

Tips for Preventing Broken Keys in the Future:

•  Regularly Maintain Your Keys: Ensure your keys are in good condition and don’t show signs of wear. If they start looking bent or damaged, replace them before they break.
• Lubricate the Lock: Apply lock lubricant regularly to prevent rust buildup that could contribute to key breakage.
• Be Gentle: Don’t force your key into the lock. If it’s difficult to turn, consider lubricating the lock or repairing it.

Conclusion

Removing a broken key from a lock doesn’t need to be stressful or costly. With these simple household items, you can successfully remove a broken key and get your door or lock working again. From using super glue to DIY key extractors like paper clips, these methods are budget-friendly and easy to execute.

If these hacks don’t work, calling a locksmith is always a reliable option. But with a little patience and the right tools, you can often solve the problem yourself!
