Car Key Replacement
The key snapped at the head while you were turning it in a stiff, frosty door lock. Half the blade is in your hand, the rest is inside the lock, and the plastic head still lights up when you press a button.
Car Key Replacement
In plain words
Losing a key is also a security event, and replacement is the moment to close it. The locksmith can erase the missing key from the immobilizer's memory during programming, so a stranger who finds it holds a blade that opens a door and a chip the car no longer answers to; the remote is unpaired the same way. If you would like to go further, every cylinder the old blade operated, doors, ignition and any trunk or fuel-door lock, can be changed so it fits nothing. You leave with new keys that work, old keys that are silent, and a note of how many keys the car now recognizes.
How the visit goesThe fob went through the washing machine in a jacket pocket. It came out clean and completely silent. Nothing unlocks, the push-button start ignores it, and the little metal blade hidden inside only opens the driver's door.

How the visit goes
The locks and ignition, not only the key
A new key is only as good as the cylinders it turns, so the check looks at the car too. A door lock that has gone unused for years on a keyless vehicle can be stiff with salt and grit; an ignition that needed a jiggle with the old key has worn wafers that will feel tight with a fresh blade; a previous replacement may have left the doors and ignition on different cuts. Aftermarket alarms and remote starters can also sit between the key and the immobilizer. Spotting these early lets the locksmith bring the right parts and explain what else the car may need so the new key feels right.
Decoding the door lock when there is no code
When the code is unavailable, the lock itself becomes the source. The locksmith works a decoding pick into the driver's door cylinder, feels each wafer to its set position and reads off the depth, producing a full cut sequence without removing the lock from the door. The blank is then cut to that reading and tried in the door and the ignition. On cars where the ignition carries an extra wafer the door lacks, the last position is found by trying the small number of possible depths. This is careful, patient work that leaves the door lock exactly as it was.
The missing key is now just metal
If a key was lost or stolen and you chose to have it erased, the car no longer answers to its chip. Whoever finds it holds a blade that may open a door and a fob that can no longer start the engine or, once unpaired, work the locks. The locksmith tells you how many keys the vehicle now recognizes, which should equal the number in your hand. If a stranger holding a working blade still bothers you, the door and ignition locks can be swapped to a new cut, and that is a separate decision you can take with a clear head rather than on the day.

What affects the quote
Same fees day, night or weekend
1Edge-cut or high-security blade
A plain edge-cut blade is cut on a code machine in moments. An internal high-security blade is milled to fine tolerances on a different machine, and the blanks themselves are dearer, so the blade type shows up in the quote.
2One working key or none
A spare added beside a working key is a shorter routine. Starting from nothing means working through whatever that vehicle's own all-keys-lost procedure calls for, commonly opening the car, decoding the lock and resetting the immobilizer, and the quote reflects those extra stages.
3Year, make and model
The vehicle decides the blank, the chip and the programming route. A twenty-year-old sedan with a plain transponder key and a recent proximity-start model are different jobs, and the quote follows the VIN rather than a flat figure.
Car Key Replacement: questions
What is a transponder key, and does my car have one?
A transponder is a small chip in the head of the key with no battery of its own. When the key is in the ignition, or the fob is inside the cabin, the immobilizer sends a signal and the chip answers with a code; if the code is unknown, the engine is prevented from running. Every new light vehicle sold in Canada since September 2007 has been required to have an immobilizer, so almost any car from that time on uses one.
Are there vehicles where the dealer has to be involved?
A few. Some manufacturers lock key programming behind data or tooling that only their dealer network can run, particularly on the newest models and on certain all-keys-lost situations. The locksmith checks your VIN against what the equipment supports before the visit and tells you plainly if the dealer route applies. Even then, the locksmith can often cut the emergency blade, open the car and handle the mechanical side so the dealer step is a small one.
Which documents count as proof of ownership?
Government photo identification plus the vehicle permit issued by ServiceOntario, the green ownership showing the VIN, is the usual pair. An insurance slip or a lease agreement in your name also works. For a company vehicle, a work order or letter from the fleet manager naming the VIN covers it. If you bought the car days ago, bring the bill of sale and the signed permit until the transfer is done.
