Broken Key Extraction
You were locking up on the way out when the key broke in the lock.
In plain words
The tools are simple and precise. A hook extractor is a thin strip of spring steel with a barb at the tip; it slides along the groove of the keyway above or below the fragment, snags one of the cuts, and walks it out. A spiral extractor works like a tiny screw, threading into the ridges of the cuts and gripping as it turns. Fine-tipped extractor pliers handle a piece that shows above the face. A tension tool brings a turned plug back to rest. None of these push inward, which is the whole point: the piece comes out the way it went in and the cylinder stays whole.
How the visit goesIn the parking lot your car key snapped in the driver's door. You are holding the plastic head with the buttons on it, the metal blade is inside the lock, and the spare is on a hook at home.
Broken Key Extraction
How the visit goes
The half in your hand
The bow and stub you are holding are worth a look before anything else. The cuts on it identify the key blank and give most of the bitting, so a replacement can be read straight from it and the fragment once they are side by side. Its condition tells a story too: thinning at the cuts, a slight bend, a crack line or a shiny worn tip all say the key was near the end of its life. The locksmith also asks about spares. A crisp spare, or the key code tag that came with the lock, is a better pattern for the new key than any worn copy.
Taking the cylinder apart to free it
Occasionally a piece is too deep, glued in, or wedged past the pins where no extractor can reach. On a serviceable, removable cylinder, the lock is serviced from behind: removed from the door or padlock (a rekeyable padlock is normally unlocked first), its cap or retaining clip taken off, and a plug follower used to push the plug out while the top pins and springs stay in place. With the plug in hand the fragment is tapped out from the rear, the pins inspected, and everything cleaned before reassembly. Where the cylinder is non-rekeyable, damaged or will not free this way, a replacement cylinder is the alternative, explained first.
Habits for the freezing months
A winter break leaves you with a dried, lubricated cylinder and one rule: when the key stops partway, you stop too. Carry a small lock de-icer in a coat pocket or the glovebox; a few seconds of it, or the warmth of a cupped hand on the cylinder, frees a frozen plug without asking anything of the blade. Shut the storm door before freezing rain, and fit a keyhole cover on a side door that catches meltwater during a thaw. Ice is one of the winter causes the locksmith sees often, alongside worn keys, misalignment and dirty or worn cylinders, and it is one of the easiest to prevent.

Broken Key Extraction
What affects the quote
Number of keys cut
Copies are counted individually. One replacement for a single occupant and four for a household are different lines, and you choose the number on the spot.
Door or strike adjustment
When the key broke because the bolt was binding in a swollen or sagging door, correcting hinges, strike or weatherstrip is offered and quoted as its own item.
Whether the plug turned before the break
A key that snapped mid-turn leaves the plug rotated and the pins holding the fragment. Easing the plug back to rest before extraction is an extra step in the work.
What to have ready
- Would you like extra keys cut while the locksmith is there?
- Is it a car key with a chip or remote buttons in the head?
- Do you own, rent or manage the property, and is identification with you?
Broken Key Extraction: questions
QuestionsDo you need my spare key?
It helps if there is one. A crisp spare is the ideal pattern for the replacement, better than the broken halves and far better than a worn copy. It also lets the locksmith test the cylinder the moment the fragment is out, which shows whether the pins and springs are sound. If the spare is itself bent or worn, mention that too; it is a candidate for retirement rather than a pattern.
Can a new key be made from the two broken halves?
Usually. Laid end to end, the halves show the full set of cuts and identify the blank, and a locksmith reads them with a gauge and cuts a fresh key to those depths on a code machine. That is better than tracing the broken blade on a duplicator, because a worn key copied is a worn key repeated. If a spare or the key code exists, that is used instead.
How long does the extraction usually take?
It depends on how the piece is sitting. A protruding fragment in a plug at rest can be out in moments. A deep piece behind lifted pins takes patient work with hooks and spirals. A glued or corroded fragment may mean removing the cylinder and freeing it from behind. Cutting and testing the new key, and any door adjustment, add their own time. The locksmith gives a sense of it after the first look.
