I searched "Manufacturers, Suppliers, Exporters & Importers from the world's largest online B2B marketplace-Alibaba.com" and they have suppliers that will bulk sell blank Mercedes smartkeys for very little money (a few dollars) and they also have suppliers to sell the equipment to program them. Just search mercedes smartkey and then later add the word programmer .

This is not my area of expertise so I bow to those who fully understand it, but it would appear that somebody could make a pile of money selling programmed keys if they had the smarts to do it. I would be glad to buy a new smartkey from a reputable outfit such as Peach Parts.

Frankly, I wish my 350 was equipped with a simple steel key system where a new one could be cut at the local locksmith for a few dollars. Anyone have a retrofit?
