Broken Key Extractor: Tools & Home Improvement

If you’ve encountered a broken key inside a lock, it can be a frustrating situation. Here are steps and considerations for safely Broken Key Extraction:

  1. Assess the Situation:

    • Examine the extent of the key breakage. If a portion of the key is still sticking out, there may be an opportunity to extract it easily. If the key is completely lodged inside, you may need additional tools.

  2. Lubricate the Lock:

    • Apply a lubricant, such as WD-40, to the lock. This can help in easing the extraction process by reducing friction between the broken key and the lock components.

  3. Use Tweezers or Needle-Nose Pliers:

  4. Key Extractor Tools:

    • Key extractor tools are specifically designed for removing broken keys from locks. These tools have a serrated edge or hooks that can grip the key fragment.

    • In cases where the key is completely lodged inside the lock, you can use a small jigsaw blade or coping saw. Insert the thin blade into the lock alongside the key and gently saw into the key until you create a groove. Once a groove is made, use pliers or the blade itself to pull the key out.

  6. Super Glue Method:

    • Apply a small amount of super glue to the end of a thin and rigid tool, such as a paperclip or bobby pin. Insert the glued tool into the lock alongside the broken key, and allow the glue to bond with the key. Once bonded, gently pull the key out.
