Key and fob listings are qualified by button count, frequency and whether the unit is new or needs pairing. A fob with the right blade and the wrong frequency will lock and unlock nothing, so check the part number on the back of the existing fob against the listing before ordering.
Cutting and programming are workshop operations performed on the vehicle with the manufacturer tooling, and are not included with the part. Where a key is supplied uncut, that is stated in the product name.
