If you are a visual learner, check out our YouTube video: How to Remove a Broken Key from a File Cabinet Lock or Desk Lock.
And remember to order a replacement for the broken key!
The solution is the broken key extractor tool. A broken key extractor fits into the lock core and essentially grabs the broken piece of the key. When the broken key extractor is pulled from the lock core, it also removes the piece of the key, leaving the lock usable. There are multiple types of broken key extractors available. To find the correct option for you, see below.
If there is space around the cut side of the broken key:
Pick the Saw Blade Style
The saw blade works by gripping the cuts of the key. Insert the extractor with the saw blade facing the side of the cut key. Apply a little pressure onto the cut side of the key while pulling the extractor out of the core.
If there is no space around the cut side of the broken key:
Pick the Spiral Style
While inserting the extractor on either side of the key, twist or spin the extractor to the right. Continue twisting while pulling the extractor out of the core.
Another available option is the hook style. This extractor has a small hook on the end and is made of steel.
EasyKeys.com also offers an interchangeable extractor set which covers it all! The HPC Interchangeable Extractor Set is the most popular on the market. It is compact, which allows you to carry a variety of extractors inside one tiny set.
