Recently I had a problem getting my car to respond to one of my smart keys, I got it to work but rather reluctantly. When I got home I opened it up and replaced the battery - with a 2032 because I didn't have a 2025 lying around. The 2032 seems to work just fine, the key clipped back together with no sign of any issue with the fatter battery. I put a new 2032 in the other key too, I figured if one was low the other might not be all that far from running out too.
I'm thinking that the 2032 should have a bit more capacity and should therefore last longer, any reason not to always use a 2032 in the Leaf smart key?
