Broken Key Extraction in Markham
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 goesYou were locking up on the way out when the key broke in the lock. Now the door is unlocked, a piece of key is jammed in the cylinder, and you were already running late for work.

How the visit goes
What happened in the second before it broke
Your account of the break is evidence. A key that snapped while you were turning against resistance points to ice, a binding bolt or a swollen door. One that broke as you pushed it in suggests grit or a damaged pin in the keyway. A key that had been sticking for weeks and finally gave up hints at worn pins or a loose cylinder cap. A key that simply cracked at a deep cut with no drama was probably fatigued metal. Each story leads to a different check after the piece is out, so a few honest sentences about the moment save guesswork later.
Bringing the plug back to rest
Nothing slides out of a rotated plug, because the pins that the key lifted are still sitting at the shear line and holding the blade. So when the key snapped mid-turn, the first job is to return the plug to its resting position. The locksmith applies gentle rotational pressure with a tension tool, feeling for the point where the pins drop back into the plug and the keyway lines up with the cylinder body. Sometimes a light tap on the face helps the pins settle. Only once the plug is at rest is the fragment free to move, and only then do the extractors go in.
A door that no longer fights the key
If the bolt had been dragging in its strike, that is corrected while the locksmith is there, because a bolt that binds turns every key into a lever. Dropped hinges get longer screws driven into the framing; a strike pocket that pinches the bolt is filed or shifted; a weatherstrip that was pushing the door off square is pared back. The test is simple: the thumb-turn should throw the bolt with one finger and no push on the door. Since wood swells in humid summers and shrinks in dry winter air, a seasonal glance at the screws keeps the key from taking the strain again.

What affects the quote
Same fees day, night or weekend
1Removing 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.
2Weather on the day
A cylinder that is frozen or iced has to be thawed and dried before extraction can begin, so a call during a deep freeze carries that patient extra time.
3Anything 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.
Broken Key Extraction: questions
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.
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.
My key is a restricted or high-security type. Can it still be extracted and replaced?
Extraction is the same careful process; the keyway is usually narrower and the cuts more complex, so it takes longer. The replacement key is different: restricted blanks are cut only from the system's records, so have the authorization card that was supplied with the system to hand, or the locksmith who installed it is contacted. Until then the spare, if you have one, keeps the door working.
