If I were to purchase a smart key for my C Class off of Ebay, how would I program it?

You can't and neither can the dealer. The keys are matched to a particular car.

I called a MB dealer and they told me that if the blank smart key you got from ebay hasn't been programed, it CAN be program at the dealer, but they cannot be RE-programed. is this correct?
thanks

I do not believe that is correct. The keys come pre-programmed from MBZ. The only thing the dealer can do is re-sync the RCL (Remote Control Locking) function. If the key doesn't work in the ignition, then it's toast.

And exactly how much is a key at the dealer?

It depends. I think the going rate is around $250. A coworker told me she got one for her CLK for $98 last month, but that was after spending over $3K in other services. There is no dealer programming necessary; they key comes ready to go from the factory, so you might have better luck "negotiating" with the guy at the parts counter - he's not on commission like the service advisors.
