Hi, did you buy the key from the Mercedes dealer or did you buy it off the internet? If you didn't buy a key from the dealer matching it to your vin number the key will not work. There is a chip in the key that must be programmed to the vin number of the car. The only keys that will work are keys purchased from a dealer or from a Mercedes locksmith.
