Broken Key Extraction
Overnight the deadbolt froze, and this morning the key would only turn partway. One more push and it sheared off flush with the face of the cylinder.
Broken Key Extraction
In plain words
Keys break for a reason, and finding that reason is half the visit. A brass key wears thinnest at its deepest cut, and after years of turning it fatigues there until a cold morning or a stiff bolt finishes it. Sometimes the lock is the culprit: grit in the keyway, a loose cap, worn pins, or a door that has dropped so the bolt binds and the key takes the strain. The extraction removes the piece; the inspection that follows tells you whether the lock needs a clean and lubricant, an adjustment, or a new cylinder, so it does not happen again next month.
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
Checks particular to a vehicle
A car adds a few questions. Did the key break in the door, the trunk or the ignition? Does the head in your hand hold a transponder chip or remote, and does the car start with the spare if there is one? Is the steering wheel locked, which can hold an ignition cylinder under tension and pin the fragment in place? Do the other doors open with the same key, or is the vehicle on a different key for the ignition and doors? These answers decide whether the job is a door extraction and a new blade, or an ignition extraction that needs the wheel freed and the wafers checked first.
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.
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.

What affects the quote
Same fees day, night or weekend
1Where the key broke
A house deadbolt, a knob, an older mortise case, a padlock, a car door and a vehicle ignition each call for different access and different care, and the quote follows the hardware.
2Anything added since the break
Glue, a second key or marks from a screwdriver mean clearing and sometimes repair before extraction can start, and that added time is named in the quote.
3Removing 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.
Broken Key Extraction: questions
My 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.
How do I stop keys breaking in future?
Look after the lock and the key ages slowly. Keep the cylinder lubricated with the product its maker specifies and free of grit, and have a binding door adjusted, since resistance raises the risk, though a worn, bent or fatigued key can still fail under normal use. Retire copies that have gone thin or kinked instead of straightening them. Cut spares from code, and rotate them so one key is not doing all the work. Take the ring weight off a car key. Small habits, but they add years.
What lubricant should I use on the lock afterwards?
Whatever the lock's own maker specifies, since cylinders differ: many call for a dry graphite or PTFE spray blown into the keyway and worked in with the key, once or twice a year, while others prohibit graphite and specify their own product instead. General-purpose oils, grease and sprays feel smooth at first but on most cylinders collect dust and clog the pins, which leads back to the sticking that breaks keys. A little goes a long way; too much of any lubricant can also hold moisture.
