Key Fob Programming: what shapes the quote

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.

How the fob was obtained

A fob purchased new for this specific vehicle, one bought secondhand, or one inherited from a used-vehicle purchase each carry a different starting point, and that history is part of what the quote considers.

Remote start and other added features

A fob supporting remote start, a separate trunk release or additional convenience buttons involves more to register and test than a fob limited to locking and unlocking, and the quote reflects that scope.

Aftermarket parts versus original manufacturer fobs

An aftermarket fob can cost less than an original manufacturer part where one is compatible, and availability varies by vehicle age and make, which the quote takes into account once compatibility is confirmed.
