Is there a case for fob?

As others have posted I too have not accidentally hit any buttons for the Prius while the FOB has been in my pocket. On my dodge truck I do it all the time. I'll be inside and the panic alarm will be going off. It's never happened with the Prius key though. I literally have my Prius FOB in my pocket 24 hours a day since there's no need to take it out of my pocket (to start the car). I'll get undressed for bed and toss my pants in the closet. The next morning I'll grab everything out of my previous days pants and toss it in the new pants. I have it in my pocket when I drive one of my other vehicles, at the Gym working out, while watching TV, doing yard work, even lying on my back under my Jeep welding on axle control arm brackets.... they're always in my pocket.
