Broken Key Extraction in Douro-Dummer
In 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
In plain words
Broken key extraction is the removal of a snapped key piece from a lock so it can go back to work. It is done with slim hooks and spiral extractors that slide into the keyway beside the fragment, catch the cuts in the blade and draw it out the way it went in. First, the locksmith confirms you are entitled to the door or vehicle. Once the piece is out, the cylinder is inspected and cleaned, since a healthy lock does not rule out a key that was already worn, bent or fatigued, and a fresh key is cut so you are not relying on the copy that failed.
How the visit goesThat key had been bending a little for years, and you kept straightening it. Today it finally cracked at the deepest cut. The stub is in the lock, and the spare you found goes in a few millimetres and stops against it.

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.
Thawing first on a frozen lock
A cylinder that broke a key because it was frozen needs the ice dealt with before the fragment will move. The locksmith works lock de-icer into the keyway, or holds gentle heat near the cylinder, until the ice inside liquefies and the plug loosens. Boiling water from the kettle stays indoors: it refreezes inside the keyway and can split a cold cylinder. With the plug free and at rest, the extraction proceeds as normal. Afterwards the cylinder is dried thoroughly and given a water-repelling dry lubricant rather than one that traps moisture, so the same morning is far less likely to repeat.
Habits that keep keys in one piece
A few small changes stop most repeat breaks. Push the key fully home before turning, and turn from the bow with a level hand, never with pliers or from the tip. Keep the house key off box-cutting and ice-scraping duty; every bend fatigues the blade at its narrowest cut. Replace a key the moment it shows a kink, a crack line or rounded cuts, and cut the replacement from code or a crisp original. Keep the ring light. If the lock itself starts to stiffen, that is the cue to lubricate or call, because a stiff lock is the one that breaks keys.

What affects the quote
Same fees day, night or weekend
1Door 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.
2Number 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.
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
Do 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.
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.
The key broke while the door was locked. Can you still get me in?
Yes. The fragment comes out first, because nothing else can happen while it blocks the keyway. With the cylinder clear and the plug at rest, the door is opened by the same non-destructive methods used for any lockout, then a working key is cut and tested. If the door is a rental, the visit is noted for the building manager on request.
