Every key that ever opened the car is gone at once, one taken with a stolen bag, the spare misplaced months ago and never replaced. There is no working key left anywhere in the house, the garage, or a coat pocket, and the car sits exactly where it was parked.
Transponder-based immobilizers became mandatory equipment on new vehicles sold across the country from September 2007 onward, though many manufacturers had already been fitting them for years before that date. Practically, this means most vehicles on the road today, whatever their age, already expect a key that carries a chip rather than a plain metal blade. A locksmith working on an older, pre-transponder vehicle follows a noticeably different process than one working on a car built after that standard became routine.

Scene 1
Some vehicles let a locksmith see and edit the key list directly once a diagnostic tool is connected to the onboard port. Others hide that list behind a manufacturer security session that has to be established first, particularly on newer models with more layers between the port and the immobilizer itself. Knowing which situation applies before starting sets the right expectation for how the visit will unfold, and for all-keys-lost work it decides whether the first step is reached directly or has to be built from nothing.
Scene 2
A diagnostic tool connects to the vehicle before any new information goes into it, and the current key list is read first so nothing already stored is disturbed by accident. This step also confirms the exact immobilizer and chip generation in front of the locksmith, since guessing wrong at this stage wastes an attempt on a system that will simply reject it. Only once the vehicle's own data is understood does the visit move toward adding, clearing, or replacing an entry in that list.
Scene 3
A spare key made before it is needed sits in a drawer doing nothing until the day the only other key is lost, and on that day it is worth more than any amount of good intention would have been. Households that arrange this while it is convenient rarely regret it, and the visit that adds a driver's key or a genuine spare is no more involved than the one that replaces something already missing. The difference is only in when it happens.

The transponder is the passive chip that talks to the immobilizer and lets the engine start; it needs no battery of its own. The fob is the separate, battery-powered piece that handles remote locking, unlocking and alarm functions. Many modern keys combine both in one housing, but they answer two different systems, which is why a fob with a dead battery can still start the car with its mechanical blade.
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.
Adding a key is meant to leave every existing key exactly as it was; the new identity is written alongside the others rather than replacing anything. The locksmith checks that the older keys still work as part of the same visit, precisely so an oversight does not go unnoticed. Only a key you specifically ask to have cleared, such as one that was lost, stops working.
