A fob went missing weeks ago somewhere between a coat pocket and a parking lot, and a spare has covered the gap since. Everything still opens and starts without trouble, which is exactly the concern: wherever that missing fob ended up, it may still work too.
Losing a fob raises a question a spare doesn't answer on its own: whoever has the missing one can, in principle, still use it. Programming a new fob is only half the service in that situation, because the other half is removing the lost fob's electronic authorization from the vehicle's memory following that model's procedure, which stops its remote and starting functions; a mechanical blade inside it can still open an unchanged door lock, so that lock is rekeyed too where the risk warrants it. The visit closes both problems at once, leaving the household with working fobs and one less fob unaccounted for out in the world.

Scene 1
A fob that has already been pried open, a battery that was already swapped, or a previous attempt at programming with a borrowed tool all change what the visit finds once it starts. Any marks on the case, any settings that already look altered, and any account of what was tried before are worth mentioning up front. None of it rules out getting the fob working, but knowing the history means the check starts from an accurate picture instead of assuming the fob is exactly as the factory left it.
Scene 2
Most proximity fobs carry a small mechanical blade tucked inside the case for the day the battery goes flat or the electronics fail entirely, and that blade is not something the programming procedure creates on its own. Where a replacement fob arrives without a cut blade, or the household wants a spare cut for the glovebox, the key is cut to the vehicle's original code or matched to an existing working key, then tested in the door's mechanical lock the same way any metal key is tested.
Scene 3
A single lost fob is a manageable problem: the vehicle's memory can be told to stop recognizing its electronic authorization, following that model's own procedure. A mechanical blade built into the fob is a separate question, addressed by rekeying the matching lock where that risk needs ruling out too. Reporting a loss promptly, rather than hoping the fob turns up, is the habit worth keeping, since a fob nobody has removed from the system keeps working for as long as it sits in a stranger's drawer or a lost bag somewhere.

A basic remote only operates the locks and alarm from a distance while a separate metal key still starts the engine. A transponder key combines a cut blade with a chip the immobilizer reads before allowing a start. A proximity fob goes further: it authorizes entry while it is nearby, though most vehicles still need the handle touched, gripped or pressed to actually unlock, and it starts the engine with a push button, with no key insertion needed day to day. Each type is programmed differently.
On many vehicles the key memory has to be reset before any new fob can be added, since nothing already accepted remains to authorize one; some vehicles instead accept an authenticated app or manufacturer service credential without a full reset. Where a reset is needed, it may take a security code specific to your vehicle or an approved access pathway built for exactly this situation. Once the reset completes, a full new set of fobs is registered and tested before the visit ends.
Yes. Adding a spare while every existing fob still works only involves registering the new one. A lost key involves that same registration plus removing the missing fob's authorization following that vehicle's own procedure, since leaving it active means whoever has it can still use it; some vehicles also relearn the fobs you keep, and a mechanical blade in the lost fob is ruled out by rekeying the matching lock. The two situations share a first step but not a last one.
