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. One worn blade on a single ring is now the entire access system for the vehicle.
Spare Car Key Duplication
In plain words
Driving on a single key means a lost pocket, a dropped bag or a worn blade can turn into a day without a car. A spare closes that gap while the original is still on hand to work from, which is the easiest moment to make one, since the vehicle, the lock system and a proven key are all present together. The locksmith matches the new blank to the blade profile, gives it the chip or code the immobilizer expects, and tests it apart from the original in every door and the ignition before calling the job finished.
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
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.
Setting up a limited valet or family spare
A spare intended for a valet, a young driver or occasional use is sometimes built without the remote functions the primary key carries, using a plain blade-and-chip key that starts the car and opens the driver's door without the trunk release, remote start or other features the household prefers to keep on one key. This is a programming choice made deliberately rather than a lesser copy: the chip is still fully recognized by the immobilizer, and the key performs exactly the functions agreed on at the start of the visit, no more and no less.
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
1Which key system the vehicle uses
A plain mechanical blade, a transponder key, a remote-head key and a proximity fob each call for different tools and different amounts of time, so identifying the system early shapes the whole quote before any cutting or programming starts.
2Reprogramming 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.
3Copying versus diagnostic programming
Some vehicles allow the chip to be copied directly from the original in one step, while others need the locksmith to connect through the diagnostic port and have the vehicle's own module enrol a freshly coded chip, which takes longer at the car.
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 should I bring to the appointment?
Bring the vehicle, its existing key, photo identification, and something that ties you to the vehicle: registration, or a document showing you are authorized to hold a key if the car belongs to someone else, such as an employer or a family member. Knowing the VIN in advance, printed or photographed from the door jamb, also helps the locksmith confirm the exact key system before arriving.
How long does making a spare car key usually take?
The time depends mainly on the key system rather than the blade. A plain mechanical key can often be duplicated within one visit, without extra electronic work. A transponder or remote-head key adds a cloning or programming step, done off the vehicle when the chip supports it and through the vehicle's own diagnostic port when it does not, with the diagnostic route usually taking longer. The locksmith can usually say which category your vehicle falls into once the make, model and year are known, before the appointment starts.
