Car Key Replacement
The only key to the car went into the lake with the kayak. Now the car sits locked in the driveway with a full tank, and there is no spare in the house, in a coat pocket or anywhere else.
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 goesMinus twenty outside, the fob button does nothing, and the door keyhole has a crust of road salt over it because you have not used a metal key in that car since the day you bought it.

How the visit goes
Parts and data lined up before the tools come out
Some vehicles hand over their security data readily; others require a PIN pulled from the car, a code from the manufacturer, or a procedure only the dealer's tooling can run. The locksmith confirms which applies to your VIN before committing to a key, and confirms the part is available: fobs are specific to frequency, part number and sometimes trim level, and a wrong one programs and then refuses to work the doors. For the systems that use manufacturer secure data, access is arranged through the industry's Vehicle Security Professional registry, which is why the ownership record is completed properly first. Nothing is cut until this line-up is clear.
Testing every function before the handover
The visit ends with a checklist rather than a handshake. The blade is tried in the driver's door, the passenger door and the trunk lock, and in the ignition where one exists. The engine is started, allowed to run, shut off and started again. Each button is pressed and watched: lock, unlock, trunk, panic, remote start. On a proximity car, the handles are approached with the fob in a pocket and the start button is tried the same way. The spare goes through the identical routine. Anything that stays silent is sorted out on the spot, and the tally of keys the car recognizes is written down for you.
Fob batteries through the cold months
A replacement fob leaves with a fresh coin cell, and a small habit keeps it that way. Most vehicles show a low-battery message on the dash weeks before the fob goes quiet; treat it as a to-do rather than an alarm. Cold reduces what a coin cell can deliver, so a battery that is fine in autumn can fail on a January morning. The locksmith shows you how the car starts when a fob is flat, usually by holding it against the start button or in a marked pocket, and where the emergency blade is released, so a dead battery is an errand rather than a stranding.

What affects the quote
Same fees day, night or weekend
1How many keys you leave with
Each key is a blank, a cut and a programming slot, so the total follows the count. Making the spare during the same visit is usually the sensible time to do it.
2Extracting a broken key
Drawing a snapped blade out of a door or ignition cylinder without harm to the lock is a separate piece of work, done before the new key is cut, and it appears on the quote as its own line.
3Condition of the locks and ignition
A door cylinder seized with salt or an ignition with worn wafers may need freeing, servicing or rebuilding for the new key to feel right. That work is quoted as its own item alongside the key.
Car Key Replacement: questions
My copied key opens the doors but the engine cuts out. Why?
The blade was copied but the chip was not. A hardware-store duplicate cut onto a plain blank has the right teeth, so it turns the locks and the ignition, yet the immobilizer hears no answer and shuts the engine off after a moment. The remedy is a proper transponder key: a blank with the correct chip, cut to your blade and programmed to the car, or a chip cloned from a working original.
Do you use original manufacturer fobs or aftermarket ones?
Both exist, and the locksmith will say which is proposed for your car. Original parts match the vehicle exactly and are the safer choice for the newest systems and for features like remote start or phone pairing. Well-made aftermarket keys and fobs are widely used on common models and suit spares and older vehicles. What matters in every case is the correct frequency, part number and chip type, which the VIN confirms.
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.
