Broken Key Extraction in Cambridge
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
A car key that breaks in the door or the ignition is handled with the same extraction tools, with one difference. On most vehicles the plastic head of the key carries the transponder chip and the remote buttons, and that half is usually intact in your hand. Once the blade is drawn out of the lock, a new blade can often be cut and fitted to the existing head, so the chip keeps talking to the car without reprogramming. The ignition wafers are checked for disturbance and the steering lock is confirmed free. Proof of ownership is asked for before work begins.
How the visit goesThe padlock on the shed has been stiff all summer. Today the key twisted, cracked at the tip, and left the end buried deep in the keyway. The rest came out in your hand, and the padlock is still closed.

How the visit goes
What has already been tried
Before choosing a tool the locksmith asks what has gone into the keyway since the break. Tweezers often push a fragment deeper; a screwdriver tip can bend pins; a drop of glue on the other half bonds to nothing useful and leaves a film that has to be dissolved before extractors will slide. A second key jammed on top of the first is a common find. None of this is anything to be embarrassed about; it just changes the plan, and knowing about it in advance means the right solvent, a plug follower or a spare cylinder is in the van before work starts.
The spiral extractor for a stubborn piece
When a fragment sits flat in the keyway with its cuts facing the pins and nothing for a hook to catch, a spiral extractor is the tool. It looks like a very fine screw on a handle. Slid alongside the blade and turned gently, its threads bite into the ridges of the key cuts and grip them. The locksmith then pulls straight back, and the fragment comes with it. A second spiral from the other side of the blade is sometimes used to steady the piece. It is slow and careful work, and it leaves the pins and springs exactly where they were.
A lock that turns like it should
The visit closes with the lock proving itself. The new key goes in fully, turns through its full travel and comes out without a catch, from both sides, first with the door swung open, then with it shut against the strike. The bolt is watched seating fully in its pocket. You are shown the fragment that came out and told what condition the cylinder was in. Anything the locksmith noticed, a strike screw backing out or a hinge that has dropped, is pointed out so it is not a surprise later. The door is locked with your own new key as the last act of the visit.

What affects the quote
Same fees day, night or weekend
1How the new key is made
Cutting from a key code or a crisp spare, decoding the two halves with a gauge, or cutting a restricted blank from system records each take different time and stock.
2Vehicle 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.
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
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.
Does the glue trick work?
It is a well-known idea and a poor one. A drop of adhesive on the other half rarely bonds to a piece of brass sitting in a tight keyway, and what it does bond to is the cylinder, the pins and the face of the lock. That film then has to be dissolved before proper extractors can slide in. Keep the halves apart and dry.
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.
