Broken Key Extraction Overview
A key can break inside a lock for several reasons — a worn key that has thinned over time, a stiff or damaged lock cylinder, cold weather making metal more brittle, or simply applying sideways force while turning. Once a fragment is lodged in the ignition or door lock, attempting to remove it with improvised tools such as tweezers or glue often pushes it deeper. A professional extraction uses hooked picks and extractor tools sized for automotive lock cylinders to retrieve the fragment cleanly.
Before the locksmith arrives, do not attempt to start the vehicle or turn the lock cylinder if part of the key is still inside — this can drive the fragment further in or damage the cylinder wafers. If possible, note roughly how deep the fragment appears to be and whether any portion is still visible. Have your vehicle's year, make, and model ready, and let the pro know whether you also need a replacement key cut after extraction.
- Works on ignition cylinders, door lock cylinders, and trunk locks
- Professional extraction tools avoid damaging lock cylinder pins and wafers
- Do not attempt to run the ignition if a fragment is lodged inside
- A new key can typically be cut and programmed in the same visit after extraction
- Mention whether any part of the broken key is still visible to help the pro prepare
