Q: I have a 2014 Honda and I am curious as to the key fob. The batteries must be at least 10 years old, and it doesn’t look like they can be replaced. I’m curious as to how long the batteries are gonna last. I hope it does not die sometime when I’m out somewhere else and trying to get started. D.B., Cheshire, Connecticut A: There is always a way to replace the battery, but it’s often not obvious.
