Spare Car Key Duplication
The blade on the everyday key has gone shiny and thin along one edge, and lately it needs a wiggle before the ignition catches. Nobody wants to be holding a failing original with nothing waiting in reserve if it finally gives out.

A vehicle that arrives with only one working key is a common situation after a private sale or an estate transfer, and it is one of the more straightforward calls a locksmith takes. Working from the single key and the vehicle itself, the blade is duplicated or cut to code, and the immobilizer chip is matched or freshly programmed so the new key is recognized on its own. Both keys are tested in the doors and the ignition before the appointment ends, which also gives the vehicle a documented second key from that point forward instead of an unknown history.
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

- 1
Deciding between copying and programming the chip
Some immobilizer systems allow a new chip to be cloned directly from the working key's own data, which lets a matching second key be produced from the original. Other systems, including some that use rolling codes or added cryptography, call instead for connecting to the vehicle through its diagnostic port and enrolling a freshly coded chip as an additional authorized key rather than a copy of the first. The locksmith identifies which method the specific vehicle and transponder support before starting the work, since the two routes use different tools and take different amounts of time at the vehicle.

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.

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.

What affects the quote
- 1
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.
- 2
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.
- 3
Reprogramming to drop a missing key
When a key is genuinely unaccounted for, having the vehicle's system stop recognizing it is separate work from cutting a new spare, and is scoped as its own step when it is needed.

Spare Car Key Duplication: questions
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.
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.
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.
49%
A mix of homes. Single-detached houses make up about 49% of homes in London (2021 Census).
In mixed neighbourhoods, a family may move from an apartment to a house or the other way around. A locksmith who knows both kinds of door can rekey the old place for the next occupant and set up the new one on the same visit.
