After I park the Prius in a locked garage, I often go into the house with the fob in my pocket. Then I forget about it until it's time to drive the Prius again (sometimes several days later). I often have to search through my pockets to find the fob. I prefer to leave the fob in the Prius so it is ready when it's time to leave. So I made an RF safe container and leave the container in the driver's side door pocket. However, I often forget to put the fob in the container, so it stays in my pocket. This fob doesn't have a key so there is no easy way to attach anything to it, and there is no way hang it. I can't believe that I am the only Prius owner with this dilemma. Any suggestions?
