Mercedez Benze 3 Buttons Car Key Shell

Replace your Mercedez Benze car key shell with three buttons. Note: There is no transponder chip included. You can simply replace your old key shell upon breakage or assuming the surface has worn-out. Just take the insides out (battery and transponder chip) and put them in this shell. You then take it to an automotive locksmith for programming, so you can use it to start your car too.
