Spare Car Key Duplication
Two coworkers share one delivery van and one key between them, trading it at the start and end of every shift in a parking lot. A missed handoff leaves someone standing beside a locked van with nowhere else to be.

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.
How the visit goesA 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.

How the visit goes

- 1
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.

Building a spare for a worn original
A key that turns with a wiggle or a fob with a soft button is not traced fault and all; instead the locksmith decodes the lock or cuts to a valid factory code for a clean blade, and separately reads or clones the chip data for the electronics, so the new key is built clean rather than inheriting the original's wear. Once the fresh key operates correctly, the worn original can be compared against it side by side, which often shows the household how much the daily key has degraded and helps decide whether it is time to retire it in favour of the newly made pair.

Where the spare should live
A spare that stays inside the vehicle solves little if the vehicle itself is what gets locked or lost, so the sensible places are a bag that travels separately, a drawer at home, or with a family member who is easy to reach. A passive proximity spare benefits from a signal-blocking pouch when it is stored, since that kind of fob keeps broadcasting even while it sits untouched in a drawer; a standard button-operated remote works differently and does not need the same pouch. Wherever it ends up, the location is worth sharing with at least one other person in the household so the spare is findable by someone other than the person who put it away.

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
How many keys are needed
Making one spare is a smaller job than producing several matching keys for a whole household or a small fleet in the same appointment, and the quote reflects how many are wanted.
- 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
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.
What testing happens before I leave with the new key?
Every door lock, the trunk or hatch, the ignition or start button, and any remote functions are checked with the new key on its own, apart from the original, so neither key is quietly helped along by the other's signal. The vehicle is started more than once to rule out an intermittent issue, and only once both keys pass independently is the visit considered finished.
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
22%
Newer homes. About 22% of homes in Whitchurch-Stouffville were built in 1980 or earlier, according to the 2021 Census.
Builders often key an entire street to a small number of keyways, which is convenient for them and less so for owners afterwards. In newer areas a locksmith can move a household onto a keyway that is genuinely its own.
74%
Mostly houses. Single-detached houses make up about 74% of homes in Whitchurch-Stouffville (2021 Census).
In areas of single houses, the door nobody watches is the side or back entry. It often has the weakest lock on the property. Fitting a proper deadbolt and a reinforced strike there is a modest job that closes the obvious gap.
