I recently purchase a 1999 C230 Kompressor. The car only came with one of the smart keys and the flat key used for opening the doors. I would like to purchase a replacement smart key and then have it programmed to work in my car. does anyone know how to go about this? I see there are keys on E-bay, but I am worried about how to get it programmed. The dealer is looking for like $180 for a replacement smart key and I think that is outrageous. Thank you for your assistance.
