Broken Key Extraction in Hamilton
You were locking up on the way out when the key broke in the lock.
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 key went in like any other morning, you turned it, and something gave with a small metallic click. The bow is still between your fingers. The rest of the blade is sitting inside the deadbolt, and the door is locked.

How the visit goes
Confirming the lock is yours to open
Extraction is an entry service in everything but name, so it starts the way a lockout does: the locksmith establishes that whoever is asking is entitled to the door, padlock or vehicle. For a home that means photo identification plus a document linking you to the address: a lease, a utility statement, or the property manager vouching for you. For a car it is the registration or ownership papers and matching identification. If your wallet is behind the door, say so, and the check is finished once you are inside. It takes a minute, protects every neighbour on the street, and is a sign you have called the right kind of tradesperson.
Drawing it out with a hook extractor
Every keyway has grooves, called wards, that run along its length above and below the blade. A hook extractor is a slim strip of spring steel thin enough to ride in one of those grooves beside the fragment. The locksmith slides it in past the broken piece, rotates it slightly so the barbed tip catches a cut in the blade, and draws it back out in a straight line. The pins are lifted clear as the piece passes them, exactly as they are when a key is withdrawn. It is a patient, felt process, and the cylinder is untouched by it.
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
Condition of the cylinder
Worn pins, a loose cap, grit or corrosion found after the piece is out may call for a service, a rekey or a new cylinder, each explained and quoted separately.
Door 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.
How 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.
What to have ready
- Where did the key break: a house door, a padlock, a car door or an ignition?
- Do you have a spare key that works, or the key code tag from the lock?
- Was the lock frozen or the door swollen when it happened?
Broken Key Extraction: questions
QuestionsMy 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.
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.
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.
