I just learned in PriusChat.com from "galaxee" that the NHW20 Prius has a procedure, TSB SS003-02, that does not require ECU replacement if the keys or fobs are lost. There will be a labor and key/fob replacement cost but not the expensive ECU. The NHW11, an earlier generation, still requires ECU replacement.
