I paid a personal visit to the Mercedes Key Center here in the Fort Worth area recently. They absolutely guarantee you cannot program an SLK remote from one vehicle to the other. They explained fully the complex reason. I immediately forgot it though [
)] One reason to buy a remote on ebay is to have a spare in case your "case" cracks or breaks, you can always use the new case. The sellers on ebay will argue all day long that you can reprogram them, but you cannot.
