Broken Key Extraction

You 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.

In plain words

If a key has just snapped in your lock, the most helpful thing you can do is nothing further to the lock. Keep the half in your hand, note whether the door is locked, and resist the tweezers and the glue, both of which push the piece deeper and add material the locksmith must clear first. On the phone, describe the lock, whether any of the blade shows, and whether the key turned when it broke. Have photo identification to hand, or the ownership papers if it is a vehicle. That short conversation means the locksmith arrives with the right extractors and a plan.

The call
A 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

Illustrative locksmith scene — Cobourg
  1. Scene 1

    The half in your hand

    The bow and stub you are holding are worth a look before anything else. The cuts on it identify the key blank and give most of the bitting, so a replacement can be read straight from it and the fragment once they are side by side. Its condition tells a story too: thinning at the cuts, a slight bend, a crack line or a shiny worn tip all say the key was near the end of its life. The locksmith also asks about spares. A crisp spare, or the key code tag that came with the lock, is a better pattern for the new key than any worn copy.

  2. Scene 2

    Cutting the key you leave with

    Once the lock is clear, a replacement key is made. The two halves of the broken key are laid together and the cuts are read with a key gauge, or the locksmith cuts from the key code if you have the tag or the lock's records, or from a crisp spare. What is avoided is copying a worn original, because a duplicate inherits every rounded cut and will stick and wear the same way. The new key is cut on a code machine, tried in the lock with the door open, then closed, and from both sides. Extra copies are cut from the new key while the machine is set.

  3. Scene 3

    A cylinder that has been looked after

    Extraction usually doubles as a service. The keyway has been blown clear of grit and salt, the pins and springs checked for wear, the cylinder cap snugged if it had loosened, and dressed with the lubricant its maker specifies rather than a one-size-fits-all product, since some cylinders take a dry graphite or PTFE spray and others forbid graphite outright. General household oils and sprays commonly collect dust and clog the pin chambers. A puff of the right lubricant twice a year, spring and fall, keeps the cylinder turning freely, and a key that starts to need force is an early message worth acting on before it breaks.

In the van

  • Tension tool for resetting the plug
  • Manufacturer-approved cylinder lubricant
  • Vehicle key blades and chip shells
  • Plug follower and cap tool
  • Key blanks and code cutter

What shapes the quoteCobourg Lock & Key Co.

Number 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.
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.
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.

Short answers to common questions

Is a broken key a sign the whole lock is worn out?

Sometimes, and the visit answers it. A key that failed from its own fatigue in a clean, smooth cylinder says nothing against the lock. A key that broke because the pins were worn flat, the cap had loosened or the keyway was full of grit says the cylinder needs a service or a rekey. One that broke in a corroded, pitted plug is telling you the lock is due for replacement.

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.

My car key snapped in the door. Is that a locksmith job?

Yes. Vehicle door locks and ignitions use wafer cylinders that respond to the same extractor tools. Once the blade is out, the plastic head you are holding, which carries the transponder chip and any remote buttons, can usually take a freshly cut blade so the car keeps recognizing it. The ignition is checked as well, since a broken key sometimes disturbs the wafers.
