Spare Car Key Duplication

A car sits at the cottage all season, and the only key to it lives on a ring three hours away in the city. Every visit begins with the same small worry about whether that ring made it into the right bag.

In plain words

Spare car key duplication puts a second working key into your hand while the first is still around to copy from. The locksmith checks that you are entitled to the vehicle, reads the blade the existing key was cut to, and gives the new blank the same electronic identity the original carries, whether that means cloning a compatible transponder chip or enrolling a fresh chip through the car's diagnostic port. Before the visit ends, the new key is proven in every door, the trunk and the ignition or start button, so you leave with two keys known to work, not one tested key and one hopeful copy.

Sound familiar?

A 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. 1

    Looking at the working key itself

    The existing key is examined for exactly what it is: a plain blade, a blade carrying a transponder chip, a remote head with buttons built into the plastic, or a proximity fob meant to stay in a pocket. Wear matters too; a blade that has thinned unevenly or a button that sticks tells the locksmith what to expect when it is time to trace or copy from it, and whether the original itself might be due for retirement once the spare exists. A key that has already been altered, filed or repaired is noted before it becomes the reference for a new copy.

  2. 2

    Testing every key before the visit ends

    Once cutting and programming are finished, each key is tested independently: every door lock, the trunk or hatch, the ignition or the start button, and any remote functions, with the other key set aside so neither test is quietly helped along by a second signal nearby. The vehicle is started and shut off more than once to rule out an intermittent fault, and remote buttons are pressed from a normal distance rather than pressed against the car. Only once both keys pass on their own is the appointment considered complete, rather than treating a single successful start as proof enough.

  3. 3

    A record worth keeping

    A short note of how many keys exist for the vehicle, what each one can do, and who holds it is a small thing to write down and a genuinely useful one to have later, whether that later is a private sale, an insurance question, or simply working out which key someone borrowed and forgot to return. This record also makes any future visit faster to start, since a returning locksmith or a different one entirely can begin from a known baseline instead of counting keys from scratch.

What affects the quote

  1. 1

    Choosing a limited-function spare

    A simplified key built for a valet or a specific driver, without every remote feature the primary key carries, generally involves less programming than matching every function exactly.

  2. 2

    Sourcing the blank or shell

    Common platforms use blanks kept in regular stock, while a less common model or an unusual shell sometimes has to be sourced specifically for that vehicle before work can begin.

  3. 3

    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

Advice · (289) 804-7704

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 is a relay attack, and does it matter for my spare?

A relay attack is when nearby equipment picks up a proximity fob's signal from inside a house and relays it to a vehicle parked outside, tricking the car into thinking the key is close enough to unlock or start. It matters for every fob in the household, spare included, which is why storing any proximity key in a signal-blocking pouch when it is not being carried is worth doing for all of them.

Does cold weather affect a key fob?

Yes, in a couple of small ways. Battery performance drops in cold temperatures, so a fob that already had a fading battery is more likely to act up on a cold morning, and a proximity system's range can feel shorter in the cold as well. Testing a spare's battery before winter, and keeping a spare battery on hand, avoids being caught out by either.

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.

Layers of paint build up on older doors and frames, and a lock that seemed to fail is sometimes a latch glued shut by the last coat. Part of the visit in an older area is freeing hardware, cleaning the edges and checking the door swings true.

23%

Single-detached houses make up about 23% of homes in Toronto (2021 Census).

Townhouse rows often share a keyway chosen by the builder. A locksmith can move a household onto a keyway of its own so a neighbour's key, or a key from the construction phase, no longer has any chance of fitting.
