Spare Car Key Duplication
A 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.
In plain words
Households with more than one driver and one car key end up trading it back and forth, which works until two people need the vehicle at once. Making a second key from the original lets each driver carry their own, cut from the same blade profile and carrying the same chip or code the immobilizer recognizes, so neither key behaves differently from the other. The locksmith tests both apart from each other in the doors and the ignition before handing them back, and a family running two vehicles on the same lock family can sometimes be brought onto one key altogether.
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
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.
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.
Fewer surprises through the seasons
A tested spare carries a household through the situations that tend to arrive without warning: a fob battery finally dying in the cold, a blade thinning out after years on the same ring, or a key simply not being where it was left that morning. None of those moments needs to become a locksmith call anymore, because the second key was already proven capable of everything the first one does, sitting wherever it was agreed to live, ready for the day it is actually needed.

What affects the quote
Matching two vehicles to one key
Bringing a second vehicle onto the same key, when the two lock systems are compatible, takes more identification and testing than producing a spare for a single car alone.
Condition 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.
Timing 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.
What to have ready
- What year, make and model is the vehicle?
- Where is the vehicle usually parked?
- How many spare keys would you like made?
Spare Car Key Duplication: questions
QuestionsWill the spare include the remote buttons?
If the original has remote buttons and you want the spare to match, yes: the new key or fob is programmed to the vehicle's receiver so locking, unlocking and any other remote function respond the same way from either key. If a simpler spare is preferred instead, the remote portion can be left out while the chip that starts the car is still fully recognized.
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.
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.
