Most vehicles on the road pair a cut metal blade with an invisible electronic layer, a chip in the head that the immobilizer checks before the engine is allowed to start. Duplicating a spare means reproducing both halves, not just the shape of the blade, so the process depends on what year and system the car actually uses. An older mechanical key copies directly from the blade on a duplicating machine. Transponder and remote-head keys add a chip that is copied or freshly coded through the vehicle's diagnostic connection. Proximity fobs add pairing over radio, and every path ends with a second key that starts the car.
How the visit goesA lockout last month ended with a locksmith opening the door and going home, and the same single key has been carried ever since with nothing behind it. The relief of getting back in faded within a week into the same exposure.

How the visit goes

- 1
Checking how many keys already exist
A vehicle can be sitting on more than the one key its owner mentions, and an honest account of every key, valet key and remote in circulation shapes what happens next. If two or three already exist and work, a new spare simply joins that set. If a key was lost some time ago and never accounted for, that shifts the conversation toward reprogramming the whole system to drop the missing one, rather than quietly adding a fourth key to a set that already has an unknown copy loose somewhere. Either way, knowing the real count is worth establishing before cutting begins.

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
- 1
Copying versus diagnostic programming
Some vehicles allow the chip to be copied directly from the original in one step, while others need the locksmith to connect through the diagnostic port and have the vehicle's own module enrol a freshly coded chip, which takes longer at the car.
- 2
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.
- 3
Fob battery and physical condition
A fob that needs a fresh battery or shows cracking or water exposure adds a small amount of extra work beyond programming a key that is otherwise in good shape.

Spare Car Key Duplication: questions
Is there a reason to make a spare now rather than waiting until the original is lost?
The whole process depends on having a working key to read or trace from, so making the spare while that key still exists is simpler than the alternative of proving ownership without any key present and building access from scratch. A spare made now also means a future lost key is solved by reaching for the second one already tested and waiting, rather than starting the whole process from nothing.
What 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.
What if I have lost track of how many keys already exist for the car?
That is worth mentioning when you call, since it changes the plan. If the count is genuinely unknown, or a key was lost at some point and never accounted for, reprogramming the vehicle to accept only the keys currently in hand is often the sounder route, rather than adding a new spare on top of an uncertain set that might include a key nobody can locate anymore.

What the census means at the door
58%
Older homes. About 58% of homes in Toronto were built in 1980 or earlier, according to the 2021 Census.
Basement and side entries on older homes were often fitted long after the house was built, with whatever lock was on hand. Bringing those doors up to the standard of the front entry, and onto the same key, is a common and satisfying job.
23%
Single-detached houses make up about 23% of homes in Toronto (2021 Census).
Landlords and property managers dominate in attached housing, and they want keys organised. A locksmith sets up master systems so a manager carries one key while each tenant's key opens only their own door.
