Smart key battery life

How long does the D4 smart key last with a new battery?
I would assume due to the keyless entry it's in someway on all the time unlike the D3

Thanks

All batteries are not the same…. and watch for the shelf life and manufacturing date.
I just make it a habit of changing all my fob batteries, once a year. Probably overkill but I’m like that.

D3's key is rechargeable, and is charged when in the ignition. D4 key has a cell which is being used until its flat.
