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.

In plain words

Making a spare before the original goes missing is simpler than making one after, because the whole process is built from a working key to read or trace from. With the vehicle and its existing key both present, the locksmith identifies the blade profile and the chip or coding the immobilizer expects, produces a matching blank, and gives it the same electronic identity as the first key. Testing both keys side by side in every door and the ignition confirms the spare performs the same way, so a future lost key becomes an errand rather than a call for entry.

The call
The paperwork for the used car changed hands last week, and the previous owner mentioned, almost as an afterthought, that a second key never turned up. One worn blade on a single ring is now the entire access system for the vehicle.

How the visit goes

  1. Scene 1

    Locating the right blank

    A correct spare starts with the correct blank: the same blade profile as the original, and where relevant the same shell shape for a remote head or proximity fob so the buttons and battery compartment line up. Aftermarket blanks exist for most common platforms, while a less common or very recent model sometimes calls for a shell sourced specifically for that vehicle. Getting this step right avoids a mismatch discovered only after cutting has begun, and it is one of the reasons the vehicle's year, make and model are confirmed early rather than assumed from the look of the current key.

  2. Scene 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. Scene 3

    Keeping the household on one system

    If the household runs more than one vehicle or more than one driver, this is a natural point to confirm every key still works the way it should: the original, the new spare, and any older keys already sitting in a drawer. A round of testing the whole set against the vehicle, rather than assuming a key still works because it once did, catches a fob with a fading battery or a blade that has quietly started to wear before it turns into a problem on a morning when someone is already running behind schedule.

  • VIN and key-system reference

What shapes the quotePreston Locksmith Co.

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.
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.
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.

Good questions about locks

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.

How should I store the spare once I have it?

Somewhere other than inside the vehicle, since a spare kept in the glovebox solves little if it is the vehicle itself that becomes inaccessible. A bag that travels separately, a drawer at home, or a trusted family member all work. A passive proximity spare also benefits from a signal-blocking pouch during storage, since that kind of fob keeps broadcasting even sitting untouched in a drawer; a standard button-operated remote does not need the same pouch.

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.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 48 in 100 homes · mixed ages
  • About 48% of homes in Cambridge were built in 1980 or earlier, according to the 2021 Census.Mixed housing stock keeps a locksmith versatile. A morning might be a heritage mortise lock rebuilt and an afternoon a smart lock paired to a phone on a steel door. The same care goes into both, with tools and parts for each.
  • Single-detached houses make up about 57% of homes in Cambridge (2021 Census).Mixed housing brings mixed hardware ages as well as types. A locksmith may rebuild a mortise lock on a semi-detached house and then set up a keypad on a townhouse door across the road, and treats each with the care its owner expects.
