I am now accustomed to the remote fob for unlocking and starting the car, but I was worried enough when I first got it that I got a "Tile" tracker for it (and have so far replaced the battery in each at least once.) There is no ignition keyhole, so though there is a key tucked inside the fob, it only gets you into the vehicle, it doesn't guarantee you can start it. That's a good idea about the spare battery. I'll put one in the console today.
