The car came with a single key when the sale went through, and that key is the only thing standing between the household and being stranded. A second one has been on the list for weeks, quietly moved down every time something more urgent came up.
When every key for a vehicle is genuinely gone, there is nothing left to vouch for a new one, so the visit starts by re-establishing secure access to the immobilizer's own module, sometimes through the vehicle's manufacturer network. Only once that access is confirmed can a fresh key be cut and its chip written in. It takes longer than adding a spare with an existing key on hand, but it follows the same underlying logic and finishes with the same test: an engine that starts on the new key alone.

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
All-keys-lost work follows a different path, because there is no working key left to prove the vehicle's trust to a new one. The locksmith first re-establishes secure access to the immobilizer's own module, sometimes through the vehicle's manufacturer network, before a fresh key list can be written at all. Once that access is confirmed, the new key or keys are added the same way any other key would be, and the process finishes with the same start-up test as a routine replacement.
Scene 3
The visit ends with every key that should work actually tested in the driver's own hands: the new one, and any older ones that were meant to keep working. Remote functions, if the vehicle has them, are checked at a normal distance, and the emergency insert on a proximity fob is pointed out rather than left for the owner to discover later. Nothing is assumed finished on the strength of a screen reporting success; the engine and the fob both had to prove it directly.

The metal blade and the passive chip inside it are not affected by cold. The fob's battery is a different story: cold weather reduces a battery's effective output, which can turn a marginally weak battery into one that suddenly stops responding on a cold morning. Testing a fob's battery before winter sets in catches this early.
Nothing changes about it. A spare is added alongside the existing key without clearing or altering anything already stored in the vehicle's memory. The only keys that get cleared are the ones you specifically identify as lost, stolen, or no longer wanted, and that is confirmed with you before any clearing happens.
All-keys-lost work starts by re-establishing secure access to the vehicle's own immobilizer module, since there is no existing key left to vouch for a new one. Once that access is confirmed, a fresh key is cut and its chip is written into the vehicle the same way any key would be, and the visit finishes with the usual start-up test across a few ignition cycles.
