How to Remove a Broken Key from a Lock: Simple DIY Methods
Small mishaps can happen at any time—often caused by worn-out locks, rushed movements, or defects in the key itself. One of the most frustrating (and common) situations is a key snapping and getting stuck inside the lock.
When this happens with house keys, delaying the fix usually isn’t an option. Before you call a locksmith or start taking the lock apart, try the following practical techniques to extract a broken key from a lock safely.
If the Broken Key Is Visible from the Outside
1) Use a Strong Magnet
This method works best when the key fragment is positioned vertically and is accessible.
- Apply a small amount of lubricant around the key and into the lock.
- Hold a powerful magnet against the exposed piece of key.
- If the metal responds to the magnet, the fragment should attach and slide out with minimal effort.
2) Pull It Out with Needle-Nose Pliers (or Thin-Tip Scissors)
If part of the key is sticking out, this is often the quickest option.
- Spray or apply lubricant around the broken piece.
- Use needle-nose pliers or scissors with very slim tips to grip the visible end.
- Pull slowly and steadily—avoid jerking or tugging hard, as that can push the key deeper into the cylinder.
If the Key Broke but the Door Is Still Open
When the door is open, you may be able to push the fragment out from the other side instead of pulling it.
1) Push It Out with Scissors from the Inside
- From the inside side of the lock, insert a thin scissor tip (or another narrow tool) until it touches the broken key.
- Gently press forward to push the fragment outward.
- If it comes out partially, finish the job by gripping it with pliers and pulling it free.
2) Push the Fragment Out Using Another Key
This approach is similar to the previous one, but uses a key instead of scissors.
- Insert another key from the inside side of the lock.
- Carefully push forward so the stuck piece is forced outward.
- Once it protrudes enough, remove it using pliers.
3) The Melted Silicone Method (Popular and Effective)
This technique became widely shared online because it can work surprisingly well when the fragment is standing vertically.
- Heat a small piece of silicone with a lighter until it softens and melts.
- Quickly press the softened silicone onto the lock area where the key is stuck.
- Hold it firmly in place for about a minute, allowing the silicone to cool and grip the key.
- Pull the silicone back carefully to extract the key fragment—don’t yank too hard, or the silicone may tear.
