Nothing wrong with that. I always have mine with me. I have taken one drive without it. It unlocked when I went into the garage, so I got in and drove away. When I got to the restaurant, I realized I didn't have it. It was the first time in my life that I had driven someplace without a key or fob and it felt totally strange. I was sure I would get out of the car and it would turn off and then not let me back in. But it was fine. Which probably means I don't really need to have it with me, but I feel more secure when I do.
