The remote clicks the way it always has, but the vehicle no longer locks, unlocks or answers with its usual chirp. Nothing on the dash reacts either.
A used vehicle bought with one fob, or none, leaves a household relying on a single point of failure or locked out entirely. Programming for a used purchase starts by confirming the buyer's ownership of the vehicle, since a fob for someone else's car is not something added casually, and continues by registering the fobs the new owner actually holds to the vehicle they now own, on record from that point forward.

Key Fob Programming · Hamilton
Scene 1
Before any fob is touched, the person requesting the work is asked to show a claim on the vehicle: registration, a bill of sale, an insurance document, or simply being present with the vehicle and its existing key. This matters for a car in the same way it matters for a house, since a fob is a way into someone's property and, on many vehicles, a way to drive off in it. Confirming ownership takes a minute at the start of the visit and settles a question that would otherwise hang over the rest of the work.
Scene 2
With the vehicle and the fob identified, the registration procedure runs through a diagnostic connection built for that specific system, most often the same port used for other vehicle diagnostics. The exact sequence that model calls for is followed step by step, since the order and the timing between steps varies from one manufacturer to the next. When the procedure completes, the fob is now part of the vehicle's accepted list rather than an unrecognized piece of plastic with buttons on it, and it is treated as a working key from that point forward.
Scene 3
For a vehicle that turned out to need manufacturer-level access, the household leaves the visit with a clear picture rather than an unresolved gap: what was tried, what the vehicle actually requires, and which fobs are ready to go the moment that next step happens. Nothing sourced during the visit needs to be redone, and the eventual appointment, wherever it happens, starts from a documented position instead of repeating the same identification work from scratch.

This depends on the manufacturer, since each vehicle's memory has a set limit built in, commonly enough for several drivers plus a spare. The visit checks how many the specific vehicle allows and how many are already registered, so a household adding another driver knows whether there is room before a new fob is ordered.
Each function the vehicle offers is tried in person once the fob is registered: trying whatever passive-entry action that vehicle actually needs, approach alone, or a handle touch, grip or button press, pressing the remote start button and confirming the engine turns over, and checking that the vehicle re-locks or shuts down the way it is meant to. Nothing is assumed to work simply because the fob was accepted by the vehicle's memory.
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.
