You should change both your keyfob batteries every 6mo, even if they're not dead. Same goes for changing headlight bulbs, tail-light bulbs, license plate bulbs, and your smoke and CO detector batteries (if they're not running off house electricity). Change all of them every 6mo, and you'll never have to worry about being locked out, pulled over, or dying in a house fire. A little work 2 times a year will save you a LOT of hassle and traffic tickets, and could save your family's life.

I’ve just realised there are two me’s.
The responsible ’work me’ that would totally do this for work and have it scheduled in a calendar that I actually looked at and actioned.
Then there is the ‘home me’ that is more ‘she’ll be right I’ll just get a new battery when the old one dies and/or when my smoke alarm starts beeping at 3am’
😐😐😐
I'm a big fan of putting stuff like this in my Proton Calendar, and setting appropriate reminders. Then, I can flush it from my mind, and forget all about it until my phone reminds me. I think that's a good use of technology.
