Why Broken Key Extraction Requires a Specialist, Not a Guessing Game
When a key snaps inside a lock, the instinct is often to try fishing it out with whatever is nearby — a bobby pin, a thin knife blade, or a flathead screwdriver. In nearly every case, this pushes the broken fragment deeper into the cylinder, scores the internal pin stacks, or jams the plug so thoroughly that what started as a simple extraction turns into a full lock replacement. This is especially true with mortise lock cylinders, which are common in older Suffolk commercial buildings and historic properties near the downtown waterfront. Mortise lock internals are precision-machined; forcing any improvised tool into the keyway risks bending the driver pins or cracking the plug, adding significant cost to a repair that a trained technician could have resolved cleanly in minutes.
Our technicians arrive equipped with extraction hooks, broken key extractors of multiple profiles, and plug followers sized to match residential deadbolts, commercial mortise lock cylinders, door knob lock cores, and automotive ignition locks. The process involves identifying exactly how far the fragment has traveled, whether the plug is in the shear line or has rotated, and which extraction approach keeps the lock intact. In many cases — particularly with quality hardware like Schlage or Kwikset deadbolts — the cylinder is fully salvageable after a clean removal, meaning no new hardware is needed at all.
