The new key slides into the ignition and turns exactly the way the old one did, but the engine only cranks. A dashboard light blinks near the fuel gauge, and no amount of turning the key gets the car past that cranking sound.
A modern car key is often two systems living in one housing: the transponder, a chip with no battery of its own that only the immobilizer needs to see, and the fob, a battery-powered remote that handles locking, unlocking and alarm functions from a distance. Programming a transponder key addresses the first system, letting the engine start, while pairing the fob addresses the second, restoring the buttons. A key can pass one test and fail the other, so both get checked before the visit is finished.

Scene 1
The physical key gets its own inspection. A blade is checked against the lock for wear, a remote-head or proximity fob is opened to check its battery and contacts, and any chip visible in the key head is checked for cracks or separation from the blade. A key that was cut at a counter kiosk but never programmed is common enough to check for specifically: the metal fits the lock perfectly, and the confusion is understandable when the same piece of plastic looks complete either way.
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
A fob that survived one winter will not necessarily survive the next one on the same battery, since cold weather is genuinely harder on a battery that was already getting weak. Testing it before the temperature drops, rather than after it has already failed on a frozen morning, catches a fading battery while replacing it is still a small errand rather than an unplanned one. The metal blade inside a proximity fob does not mind the cold at all, which is exactly why it is worth knowing where it is.

It can, mainly because a remote starter is often wired into the same ignition and immobilizer circuits a new key needs to talk to. The locksmith asks about any aftermarket installation before starting, and if it is involved, checks how it was wired in rather than assuming the factory system is untouched underneath it.
It depends on the vehicle and what its factory ignition system supports; some older models can accept an aftermarket immobilizer and matching transponder key, while others were never built with a compatible module at all. This is worth discussing model by model rather than assuming either answer, since the mechanical side of an older ignition is often the easier half of that conversation.
Its identity is deleted from the immobilizer's memory during the same visit that adds the replacement, using the same connection to the vehicle's module. Once cleared, that key still opens a mechanical lock it happens to fit, but it no longer authorizes the engine, which removes the part of the vehicle that actually matters to whoever might be holding it.
