I believe if you carry the key around you engage the battery more. most higher end cars have a movement sensor that 'powers' up the key some. This is an anti-theft feature to stop those 'key scanning' theft attempts. I don't know for certain this is in the Defender's key, but I know it was in our Polestar 2's key. So if you don't keep it in a purse or pocket while you're doing your daily work and leave it on a table or key hook it should last a bit longer.
That said I've noticed as time goes on the newer cars batteries in the key fob last a lot less. I have a stack of CR2032s for a lot of things like car keys

I'm similar with a stack of spare batteries at home, I just set a reminder in my calendar to change the batteries once a year. One might get longer life out of them, but no way they are lasting 4-5 years.

If you push the start button for your engine and you notice it's slow to start up... this happened to me on my LR2. It started fine for maybe a year or two, but after then I noticed it was iffy sounding when I hit start. The dealer looked it over and replaced a chip or panel that controls the engine starting up. Fully resolved after dealer put in a new piece that was controlling the engine start process. Maybe the same for you?
