My key fob died already. Only lasted three months. Fob was not near the car when not in use. Wish I got a warning. Came to my car after work and no response. I tried the key spot near the door and falcon wing and no response. Ended up opening the car with my phone. But when I got home I got out of the car and left my phone in the car. The car locked me out so I was lucky that I had my spare at home. Sigh.
