Since the remote starter was installed last month, the original key has started acting strangely, the car catches on the first turn some mornings and refuses outright on others. Nothing about the key itself changed, but whatever the installer touched under…
Some vehicles let a locksmith reach the key list directly through the onboard diagnostic port with the right equipment, which keeps a spare or replacement fairly direct. Others, especially newer models, gate that list behind a security session tied to the manufacturer's own network, adding a step before any new key can be written. Knowing in advance which category a vehicle falls into sets realistic expectations for how the visit will unfold, rather than assuming every car behaves the same way under the dash.

Scene 1
The next question is not about the lock but about the keys: how many currently work, whether one was lost or stolen, and whether every key for the vehicle is genuinely gone. A single missing key changes little beyond adding a spare and clearing its old identity. All keys lost changes the whole visit, since there is nothing left to prove the system already trusts, and the work has to start by re-establishing that trust before a single new key can be written.
Scene 2
The mechanical side of the job comes first and is the more familiar half of it: the blade is cut to the lock's own pattern, either from a code on file or by duplicating a working key, and fitted into a blank carrying the correct chip. A perfectly cut blade still will not start a vehicle with an immobilizer on its own, which is the detail that catches out a counter kiosk. The two halves of the key are treated as separate tasks throughout, cut first, chip second.
Scene 3
The chip inside a key head has no moving parts and asks for very little, but it does not tolerate being separated from the blade by force. A key that gets bent, snapped, or pried at with tools meant for a different job can lose its chip along with its shape, and a chip cut in half no longer answers anything. Carrying the key on a ring rather than loose in a pocket, and keeping it away from repeated hard impacts, is most of what looking after it involves.

Most commonly it means the immobilizer does not recognize the key currently in the ignition, whether because the chip has failed, the key was never programmed, or the vehicle's module is looking for a different identity than the one it is being shown. It is a useful, specific signal rather than a general warning, and it points fairly directly at a transponder issue.
Programming is done at the vehicle itself, since the equipment connects directly to it. Whether that is a driveway, a parking lot, or wherever the car happens to be, the visit travels to the vehicle rather than the other way around. The one requirement is that the vehicle is present and accessible for the whole visit, since the process reads and writes to its own onboard systems.
Many recent models, particularly ones with additional security layers, require a manufacturer-level session that only certain equipment can reach. Older and simpler systems more often allow direct programming without that extra step. The locksmith can usually confirm which situation applies to a specific vehicle from its year, make and model before the visit.
