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.
Spare Car Key Duplication
In plain words
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 car sits at the cottage all season, and the only key to it lives on a ring three hours away in the city. Every visit begins with the same small worry about whether that ring made it into the right bag.

How the visit goes
Looking at the working key itself
The existing key is examined for exactly what it is: a plain blade, a blade carrying a transponder chip, a remote head with buttons built into the plastic, or a proximity fob meant to stay in a pocket. Wear matters too; a blade that has thinned unevenly or a button that sticks tells the locksmith what to expect when it is time to trace or copy from it, and whether the original itself might be due for retirement once the spare exists. A key that has already been altered, filed or repaired is noted before it becomes the reference for a new copy.
Working from a used or single-key vehicle
When only one key exists for the vehicle, the whole process leans on that single copy: its blade is traced or measured, its chip is read where the system permits it, and every remote function it performs is noted before work starts, since there is nothing else to check against. The new key is built to match, then tested on its own, away from the original, to confirm it genuinely operates independently rather than only appearing to work while the first key happens to be nearby with its own signal still in range.
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
Same fees day, night or weekend
1Manufacturer-specific security systems
Certain manufacturers build key systems that call for specialized equipment or additional authorization steps, which can mean more time at the vehicle than a more widely supported system.
2Timing 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.
3Choosing 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.
Spare Car Key Duplication: questions
What identification do I need to bring for a vehicle that isn't mine, like a company car?
Bring whatever document shows your connection to the vehicle in that situation: a company letter or fleet record for a workplace vehicle, a lease agreement for a rented one, or a note from the registered owner for a family member's car. The locksmith is confirming that the person asking for a key is entitled to hold one, which protects the vehicle's owner as much as it protects you.
What happens if I only have one key and it is for a car I just bought?
This is a common and straightforward call. The locksmith works from the single existing key and the vehicle itself, identifying the blade profile and reading or matching the chip, then testing the result on its own before the visit ends. It is also a good moment to confirm how many keys the car's history suggests should exist, since a private sale sometimes changes hands with an unknown key already out of circulation.
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.
