However, the local dealer says that for a few hundred bucks, they can program the code into the remote (or maybe they meant program both with a new matching code). They seemed quite sure about this and even quoted me a not particularly exorbitant price to do this if I can get the basic fob.

Seems the common scheme is to make each remote with unique code built in - then have the vehicle's engine computer adopt that code when set to "learn" mode. This may involve turning on the ignition and pressing a few buttons inside the car.

However, one must first obtain a remote fob that is compatible with the car model in terms of radio frequency and code format.

I have come across both 24 and 40 bit rolling codes which allow billions of possible codes to be generated.
