Replace battery key

I have just changed the battery in my key fob only a month ago and I have bought a new start button for my keyless go.
Is my key battery toast or is there some calibration method to not have the message come up?

I believe it has to do with the distance between your car and your keys. IIRC, if they're too close they'll be in communication constantly and the FOB battery will die a quick death.
