Broken Key Extraction
You were locking up on the way out when the key broke in the lock.
In plain words
Freezing is one of the bigger seasonal causes of broken keys here. Meltwater runs into the keyway during a thaw and freezes overnight, so the plug is locked in ice, and most people respond by turning harder. The blade gives before the ice does. A winter extraction visit therefore begins with thawing: lock de-icer or gentle warmth frees the plug, then the fragment is drawn out and the cylinder is dried and given the lubricant its maker specifies. You leave with the piece out, a new key cut, and a small tube of de-icer so the next frozen morning is a pause rather than a snap.
How the visit goesA roommate tried to help with tweezers, then by gluing the other half to it. The fragment is now further in than it started, there is dried glue around the keyway, and the front door still does not open.

How the visit goes
How the piece is sitting
The first look is at the fragment itself, without touching it. Does any of the blade show above the cylinder face, or is it flush or deeper still? Is the plug sitting at its normal rest position, or did it stop partway round when the key gave way? A protruding piece in a resting plug is the simplest case. A fragment past the shear line in a rotated plug means the pins are holding it, and the plug has to be brought back before anything will slide. Reading this correctly decides which extractor comes out of the case and spares the keyway from needless probing.
When the piece is standing proud
A fragment that shows above the cylinder face looks like the easy case, and it is, provided nobody pushes on it. The locksmith grips it with fine-jawed extractor pliers or needle-point tweezers made for the purpose, steadies the cylinder with the other hand, and pulls straight out along the line of the keyway. If it resists, the plug is checked for rest position rather than the pull being increased, because a piece forced against lifted pins can bend them. A trace of dry lubricant at the keyway entrance eases a tight fit. The piece comes out whole, and the lock is ready to test.
A clear record for the landlord or manager
If the lock belongs to a rental unit, a condo or a workplace, you get a plain account of what was done: the fragment removed, the cylinder inspected and serviced, any key cut, and whether a rekey or replacement was recommended. Tenants and landlords in this province each carry obligations when locks are changed and keys are shared, so if the cylinder was replaced or rekeyed, the note records who now holds which key. For a property manager it closes the ticket cleanly; for you it means the next conversation about that door starts from facts rather than memory.

What affects the quote
Vehicle key electronics
Fitting a new blade to a chip head, or moving the chip and remote into a new shell, is separate from the extraction and quoted as such, as is any ignition check.
Removing the cylinder to free it
A deep or bound fragment may need the cylinder taken off the door and the plug pushed out from behind on the bench. That disassembly and reassembly is quoted on its own.
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
- Had the key been needing extra force or a wiggle lately?
- Do you own, rent or manage the property, and is identification with you?
- Do you have a spare key that works, or the key code tag from the lock?
Broken Key Extraction: questions
QuestionsMy key has a chip in it. Does that survive the break?
Usually yes. The transponder chip and the remote electronics live in the plastic head, and the head is the part that stays in your hand when the blade snaps. Once the blade is extracted, a new blade of the right profile is cut and fitted to the old head, so the vehicle continues to recognize the chip without reprogramming. Only a cracked or soaked head needs the electronics moved to a new shell.
What should I do while I wait for the locksmith?
Put both halves of the key somewhere safe, note whether the door or vehicle is locked, and leave the keyway alone. If it is bitter cold, keep the storm door closed so the lock is not taking freezing rain. Have identification ready, or vehicle papers for a car. If the door is open, stay near it. That is all; the extraction goes smoother for a lock nobody has poked at.
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.
