Spare Car Key Duplication
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.
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.

How the visit goes
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.
Matching a remote head or fob
When the original carries buttons for locking, unlocking or remote start, the new key or fob is programmed to the vehicle's receiver so those same functions respond from the spare. This usually means putting the vehicle into a programming sequence from inside the cabin, then pressing the new remote's buttons in the order the manufacturer specifies. Some platforms allow this through the doors and ignition alone; others need the diagnostic port involved as well, particularly when the remote functions are tied into the same module that manages the immobilizer, so the two steps happen together rather than separately.
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
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.
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.
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.
What to have ready
- Does the key have buttons, a chip, or neither?
- Has a key ever gone missing that was never accounted for?
- Do you currently have one working key, or more than one?
Spare Car Key Duplication: questions
QuestionsCan spare keys be made for older vehicles without a chip?
Yes, and it is usually the most straightforward version of this service. A vehicle old enough to use a plain mechanical key has no chip to read or program, so the whole job is cutting a matching blade, either traced from the original or cut to code, and testing it in every lock the first key opens.
What if I have lost track of how many keys already exist for the car?
That is worth mentioning when you call, since it changes the plan. If the count is genuinely unknown, or a key was lost at some point and never accounted for, reprogramming the vehicle to accept only the keys currently in hand is often the sounder route, rather than adding a new spare on top of an uncertain set that might include a key nobody can locate anymore.
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.
