Spare Car Key Duplication
One key opens the car, starts the car, and rides in one pocket every day.
In plain words
Driving on a single key means a lost pocket, a dropped bag or a worn blade can turn into a day without a car. A spare closes that gap while the original is still on hand to work from, which is the easiest moment to make one, since the vehicle, the lock system and a proven key are all present together. The locksmith matches the new blank to the blade profile, gives it the chip or code the immobilizer expects, and tests it apart from the original in every door and the ignition before calling the job finished.
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


Confirming what the spare needs to do
Not every household wants an identical twin of the original. Some ask for a plain mechanical spare with no remote buttons at all, useful for a valet or a young driver who does not need trunk release or remote start. Others want every function the first key has, cut and coded to behave exactly the same in anyone's hand. Settling this before work begins decides which shell is ordered and how much programming the visit involves, and it is worth revisiting if the household's answer turns out to differ from what the person calling first assumed on the phone.
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.
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
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.
Authorization documentation
A vehicle registered to a business, financed through a lender, or owned by a family member sometimes needs an extra document confirming who may hold a key, which is sorted out before work begins.
Scheduling more than one vehicle together
Two vehicles booked into the same visit, such as a household's pair of cars, are generally more efficient to handle together than arranging two separate appointments on different days.
What to have ready
- Where is the vehicle usually parked?
- Is the vehicle registered to you, or to someone else?
- Has a key ever gone missing that was never accounted for?
Spare Car Key Duplication: questions
QuestionsShould 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.
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.
How is the electronic chip handled during duplication?
Where the transponder supports it, the chip in the working key is read and its data cloned onto a fresh chip, sometimes with vehicle-specific data pulled from the car to help. Where cloning is not supported for that particular vehicle and chip, the locksmith instead connects through the diagnostic port and has the car's own security module enrol a freshly coded chip as a new, independently authorized key.
