Has anyone here had any issues with their key fob? Lately I've had intermittent problems where I wasn't able to lock or unlock the door, and often I would have to touch the fob to the start button to start the car. Obviously my first thought was to change the battery, but after doing so, I'm still having the same issues. I'm wondering if maybe I got a bad battery, or if it's actually the fob. Anyone with similar issues?
