The data in your key is updated from the car every time that you put the key in the slot. I have comfort access in my 135i and the manual states that I should put the key in the slot every once in a while for the car to record the info to the key (especially when you are taking the car in for service). It is the same way with my '04 M3. Since I'm the only driver, I have to alternate keys every once in a while so that both keys have recent data.
