I’ve never seen extra sets of physical keys given with the pair of fobs, but they are redundant to the internal fob key, and unnecessary. You can do whatever you choose to do with them. Cut them up, leave them at home, throw them in a river, store them in a bodily orifice for emergencies...whatever you can come up with that seems clever to you.
