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 new, unregistered replacement fob is, electronically, a blank slate until it has been matched to one specific vehicle; a used fob is checked rather than assumed the same, since some OEM smart keys become permanently unusable once reset or removed from a vehicle. Programming reads the vehicle's identifying information, confirms the new fob is a compatible part, and writes it into the vehicle's accepted list. From that point the new fob behaves the same as a factory original, answering the same buttons and, where equipped, letting the engine start without the fob leaving a pocket.

Scene 1
A vehicle with at least one working fob usually calls for adding to what already exists, though some procedures need every retained fob present and re-registered rather than leaving them untouched. A vehicle with no working fob at all follows its own route: many need the key memory reset before anything is added back, while some instead accept an authenticated app or manufacturer service credential without a full reset. Sorting out which situation applies before ordering parts saves a wasted trip and sets the right expectation for how the visit will unfold.
Scene 2
Some visits are as much about the fob's hardware as its programming. A battery that has faded is swapped for a fresh one sized to what that fob calls for. A cracked case or worn buttons are replaced with a new shell built for the same electronics, so the working internals move into housing that closes properly again. None of this touches the vehicle's own settings, and a fob that only needed a battery or a shell is often back in service without any registration procedure at all.
Scene 3
With a fob programmed for each person who drives the vehicle, nobody in the household is sharing a single key or waiting for someone else to come home before leaving. Each fob remains distinct in the vehicle's memory, so a future change, such as one more driver joining or one fob eventually needing replacement, follows that vehicle's own programming mode, which on many systems touches only the one fob and on others needs every retained fob present and relearned together. The vehicle simply recognizes one more signal than it did before.

FeesSame any hour
Some manufacturers restrict fob programming to a security-gated procedure that only a dealer system or an approved access pathway can complete. When a vehicle falls into that category, the visit identifies it early, explains what the vehicle specifically requires, and documents anything already confirmed, such as a compatible fob, so the eventual dealer visit is not starting the diagnosis over from nothing.
No. Passive entry depends on the vehicle being built with the receivers and hardware for it in the first place, not just on the fob being programmed correctly. A vehicle with a basic remote-and-blade key system has no passive entry to program, no matter which fob is registered to it, so the vehicle's own equipment sets the ceiling on what programming can offer.
On many vehicles, no, not for the fobs already working: adding a fob to the accepted list does not change how they behave. Some procedures instead need every retained fob present and re-registered, so check the vehicle's own routine first. Either way, the new fob is tested for every function the vehicle offers, including remote start and passive entry where fitted.
