Which Mercedes-Benz Key Fob Do You Have?

- Smart Key: Made for older Mercedes-Benz vehicles, this key fob is usually made of plastic. Both the new and old versions of this key need two batteries.
- Chrome Keys: If you have a newer Mercedes-Benz vehicle, you most likely have a Chrome Key. This key has a metal casing and can come in one of two versions: a new model and an old model. The new version of this key needs one battery, and the older version of this key needs two.
