Does your Prius tech know more than you? Now that I have the car that's what I'm most interested in. I stopped in to my dealership today and the guys in the service dept. activated my alarm at no charge. It took thirty minutes but I really don't blame them, it's not like they had any official documentation. Just my half a$#ed recollection of what I'd read somewhere. After twenty minutes I felt bad about wasting their time. I thanked them for their effort and offered to leave but they assured me it was no bother. I finally went into the service mgr's office and found the thread on priuschat about how to do it. Five minutes later my alarm was active. In my experience a good service dept. is the most important thing about a dealership.
