I was looking into getting this done and I checked with a local (non-benz) install shop. The guy told me they would be able to do it and what they would have to do is get a key fob that had not been programmed yet, take it a part and do "some things" with it and then they would be able to do it. They were the first place that had told me they knew how to do it... but wouldn't elaborate... so I don't know if i want to spend all that money on a key fob if they don't know what they are talking about. Everyone else told me it wasn't possible bc of the security built into the computer and the key fob. And of course if you ask a Benz dealership, they will deny everything you ask them about something that is non-standard, lol. If anyone finds out for definite that this can be done, please update!
