Spare Car Key Duplication

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.

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?

One key opens the car, starts the car, and rides in one pocket every day. Nothing backs it up. A dropped storm drain, a torn pocket or a moment of distraction would leave the household without a way to drive anywhere tonight.

How the visit goes

Spare Car Key Duplication · London

How the visit goes

Double glass doors in metal frames with a horizontal push bar, beside a brick wall, with a parking lot and trees outside.
  1. 1

    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.

  2. 2

    Giving the new key its electronic identity

    A cut blade alone will turn the lock but will not start a car with an immobilizer, so the new key also needs the chip data the vehicle expects. Where the transponder supports it, the original's data is read and cloned onto a fresh chip directly, sometimes with the help of vehicle-specific data pulled from the car itself. Where cloning is not supported for that application, the locksmith instead connects to the vehicle's diagnostic port and walks the car's own security module through enrolling the new chip as an additional valid key, a process that can take longer but produces a key the vehicle recognizes on its own rather than one imitating another.

  3. 3

    Passing a key to someone else

    When the new spare is meant for a specific person rather than a drawer, such as a family member at another address or a regular caretaker for the vehicle, it is worth agreeing at handover what that person's key is expected to do and what happens if their circumstances change, such as no longer needing access. On some vehicles, removing one person's key later means the immobilizer's whole key memory is cleared and every remaining key has to be brought back and registered again, so it is worth knowing at handover whether that particular vehicle works that way.

What affects the quote

  1. 1

    Timing around the day's other calls

    A visit that fits between other scheduled stops is generally simpler to arrange than one needing a dedicated block of time set aside on its own.

  2. 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. 3

    Aftermarket alarms or remote starters

    A factory system wired into a third-party alarm or remote starter can add extra steps to programming, since the added equipment sometimes changes how the vehicle's module responds during enrolment.

Same fees day, night or weekend.

Spare Car Key Duplication: questions

Advice · (226) 777-6122

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.

Is it possible to leave out certain functions on the spare, like remote start?

Yes. A spare can be built to do everything the first key does, or scaled back to just the blade and chip that unlock a door and start the engine, without a remote start button or a trunk release. This is agreed before programming begins and is a deliberate choice rather than a lesser copy, useful for a valet, a young driver, or anyone the household wants kept to essential access.

Does the new key need to be identical to the original?

Not necessarily. Most households want a spare that behaves exactly like the first key, and that is the default. Some prefer a simpler version for a particular driver, such as a mechanical key without remote buttons for a valet or a young driver. Either choice is a programming decision made at the start of the visit, and the resulting key is fully recognized by the vehicle either way.

What the census means at the door

52%

Older homes. About 52% of homes in London were built in 1980 or earlier, according to the 2021 Census.

Period hardware on older homes deserves matching parts, not a mismatched modern set. A locksmith who works among such houses keeps finishes and styles that suit them, so a repaired or replaced lock still looks like it belongs to the door.

49%

A mix of homes. Single-detached houses make up about 49% of homes in London (2021 Census).

Mixed housing means a locksmith sees a bungalow in the morning and a condo tower in the afternoon. The stocked van has house-door deadbolts, suite-door cylinders and the finishes for each, so neither kind of customer waits for a second visit.
