Fob not fab. Can be done in 30 seconds if can find location of mechanical key insertion hole on/under dashboard. Anyone know where that super-secret-dealer-eyes-only location is on 2015 prius? Can't find it in handbook.
There is no secret location on a 2015, you just need a new keyfob and the correct software to program it. Techstream or similar will have those options. $200 sounds reasonable to me, if you don't have the software
