I've checked the archives and have pieced together a lot of information about the security technology of the SS/SE system and I have a question I could not find there. Does the SS/SE system in any way decrease the likelihood that a thief would be able to hot-wire my car? I have read that without the key fob, the Prius' ECU will act as an engine immobilizer. But even if I have the SS/SE system, can't I still open and start my car with a standard metal key? Does that mean that all Prius packages (with and without the SS/SE system ) are equally difficult (impossible) to hot-wire?
