Spare Car Key Duplication

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?

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.

How the visit goes

Singhampton

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.

  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. What a lost key means from here

    With a tested spare in hand, a lost original is worth acting on without delay rather than setting aside: the household still has a working key for the vehicle, and the locksmith can remove the lost key's access from the immobilizer so it can no longer start the car if someone else finds it. That step only addresses the electronics, though, so if the lost key's blade could still turn a matching door cylinder by hand, that cylinder is worth rekeying at the same visit rather than left as it was.

What affects the quote

Same fees day, night or weekend

  1. 1Condition 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.

  2. 2Fob battery and physical condition

    A fob that needs a fresh battery or shows cracking or water exposure adds a small amount of extra work beyond programming a key that is otherwise in good shape.

  3. 3Getting 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.

Spare Car Key Duplication: questions

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 if the fob's battery is already low?

A low battery in the original does not stop a spare from being made, since the chip and code stored inside still respond during programming even as the battery fades. It is worth mentioning the low battery when you call, though, since the new fob is a natural moment to have a fresh battery on hand for both keys and to note which type each one takes.

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.
