Spare Car Key Duplication in Toronto
A car sits at the cottage all season, and the only key to it lives on a ring three hours away in the city.
In plain words
A vehicle that arrives with only one working key is a common situation after a private sale or an estate transfer, and it is one of the more straightforward calls a locksmith takes. Working from the single key and the vehicle itself, the blade is duplicated or cut to code, and the immobilizer chip is matched or freshly programmed so the new key is recognized on its own. Both keys are tested in the doors and the ignition before the appointment ends, which also gives the vehicle a documented second key from that point forward instead of an unknown history.
How the visit goesA teenager just passed a driving test and reasonably wants a key of their own rather than negotiating over the family's single copy every time the car is needed. Two drivers and one key keep colliding on the same schedule.

How the visit goes
Assessing the fob's electronics
Where the key includes a remote or a proximity fob, the locksmith checks the battery, tests every button against the vehicle, and confirms whether functions like remote start, a panic alarm or a power hatch release are part of what the spare needs to reproduce. A fob that has been dropped or exposed to water sometimes still passes buttons but fails intermittently, which is worth knowing before it becomes the pattern a new key is measured against. Confirming the battery type while the shell is open also saves a second trip later when it eventually runs down on its own.
Setting up a limited valet or family spare
A spare intended for a valet, a young driver or occasional use is sometimes built without the remote functions the primary key carries, using a plain blade-and-chip key that starts the car and opens the driver's door without the trunk release, remote start or other features the household prefers to keep on one key. This is a programming choice made deliberately rather than a lesser copy: the chip is still fully recognized by the immobilizer, and the key performs exactly the functions agreed on at the start of the visit, no more and no less.
Two keys, both proven
The visit ends with two keys that have each been tested on their own: every door, the trunk or hatch, the ignition or start button, and any remote functions. Neither key is a backup that has only been assumed to work, and neither is treated as the senior copy. It is worth deciding on the spot which key rides on the daily ring and which goes into storage, and writing that decision down somewhere the household will actually check later, such as a shared note or a label on the ring itself, rather than trusting memory a year from now.

What affects the quote
Whether remote functions are included
A spare limited to the blade and chip that unlock and start the vehicle involves less programming than a full match of every remote button the original carries, and the quote follows whichever is chosen.
Getting to the vehicle
Straightforward access, such as a driveway or an open lot, is simpler than a locked underground garage, a gated lot or a vehicle parked somewhere with restricted entry, which the quote accounts for.
Condition of the working key
A clean, unworn original traces onto a blank without much fuss, while a thinned or damaged blade may need cutting to a factory code instead, which is a different process with its own materials.

Spare Car Key Duplication: questions
QuestionsWhat if the fob's battery is already low?
A low battery in the original does not stop a spare from being made, since the chip and code stored inside still respond during programming even as the battery fades. It is worth mentioning the low battery when you call, though, since the new fob is a natural moment to have a fresh battery on hand for both keys and to note which type each one takes.
Should I get the locks rekeyed when I get a spare, or is that a different service?
They are related but not identical, since a car's door and ignition locks are a separate mechanical layer from the immobilizer even though both systems usually get touched in the same visit. Making a spare and removing a genuinely unaccounted-for key's electronic access are handled together, and if that lost key's blade could still turn a matching door cylinder by hand, the locksmith rekeys that cylinder as part of the same appointment.
Can a spare be made from a key that is already worn?
Yes, and it is often a good reason to make one. Rather than tracing every rounded edge of a worn blade onto the new copy, the locksmith can decode the lock or cut to a valid factory code for the blade, then read or clone the chip data separately for the electronics, producing a spare that is cleaner than the original rather than a copy of its wear. The worn key can then be compared against the fresh one and retired if it is due for that.
