To summarize for you:

• An ebay fob will never start your car.
• An ebay fob may not be able to be programmed to open your cars locks remotely

I don't know about getting the physical key cut.

The thread Shawnkey wrote, is for programming keys that you bought from the dealer. Some dealers charged unsuspecting owners to program the key. Shawnkey's thread shows how to avoid that charge by doing it yourself.
