- The call
- A 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.

One key opens the car, starts the car, and rides in one pocket every day. Nothing backs it up.
Most vehicles on the road pair a cut metal blade with an invisible electronic layer, a chip in the head that the immobilizer checks before the engine is allowed to start. Duplicating a spare means reproducing both halves, not just the shape of the blade, so the process depends on what year and system the car actually uses. An older mechanical key copies directly from the blade on a duplicating machine. Transponder and remote-head keys add a chip that is copied or freshly coded through the vehicle's diagnostic connection. Proximity fobs add pairing over radio, and every path ends with a second key that starts the car.

Spare Car Key Duplication · Sandy Cove

Scene 1
Not every household wants an identical twin of the original. Some ask for a plain mechanical spare with no remote buttons at all, useful for a valet or a young driver who does not need trunk release or remote start. Others want every function the first key has, cut and coded to behave exactly the same in anyone's hand. Settling this before work begins decides which shell is ordered and how much programming the visit involves, and it is worth revisiting if the household's answer turns out to differ from what the person calling first assumed on the phone.
Scene 2
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.
Scene 3
When the new spare is meant for a specific person rather than a drawer, such as a family member at another address or a regular caretaker for the vehicle, it is worth agreeing at handover what that person's key is expected to do and what happens if their circumstances change, such as no longer needing access. On some vehicles, removing one person's key later means the immobilizer's whole key memory is cleared and every remaining key has to be brought back and registered again, so it is worth knowing at handover whether that particular vehicle works that way.

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.
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.
The VIN identifies the exact immobilizer generation and lock system your particular vehicle left the factory with, which decides whether the chip can be copied directly or needs to be freshly coded through the diagnostic port, and which blank and blade profile are correct. Two cars that look identical from the outside can use different systems a model year apart, so the VIN removes the guesswork.
