Cannot be reprogrammed. Each key fob is set at factory for each vehicle. The is a key 1 or a and a key 2 or b. You must take car to dealer to have them tell you which key you have in order to order the matching fob. Otherwise if you order you could get the same as you have and then it is canceled and you are back to only one key. Also for the life of a Mercedes a total of apprx. 12 keys can be made before the computer system has to be replaced. So long story short you have to go to dealer to get new key fob.
