Comfort access FOB battery
One of my FOB has stopped working, cannot lock the car anymore and needed to insert it in the slot to start it. Car is only a year old so kind of surprised the battery is dead.
Anyways I popped it open and saw replaceable battery. I called up my local dealer to see if they could replace it and they told me it is rechargeable and I just need to put it in the slot. Told him I had comfort access and he again he told me it is rechargeable. To me it looks like a standard replaceable battery that I assume does not charge. So what is up? thanks jeff |

It charges indirectly in the slot or so am told. I always cycle my key fobs and insert it every now and then into the slot to avoid something like this from happening. Bring both sets of keys and take a long drive with the dead key fobs plugged and see how it goes from there. Good luck and keep us updated.

Odd....I thought I read in the manual to place the key in the dash on long trips to charge it.

What's the life expectancy of the batteries? And can you buy them anywhere or does BMW have monopoly on FOB batteries?

yeah I was kind of surprised, think he has the opposite problem, probably most people do not have comfort access and come in complaining about the dead battery.
looks like a standard battery you can buy anywhere |

Was certainly thinking it was rechargeable as I have been told that it was. According to the owners manual:
"Each remote control contains a rechargeable battery that is automatically recharged when it is in the ignition lock while the car is being driven. Use each remote control at least twice a year for longer road trips in order to maintain the batteries' charge staus. In cars with convenient access* the remote control contains a replaceable battery, replace battery + side up... all that said, I was told the battery in my FOB was rechargeable. I was getting the low battery indicator and put the FOB in the ignition lock and the low battery warning indicator hasn't come back..... |

This isn't complicated. It's a battery. It's not rechargeable. They don't normally last more than a year, sometimes less. You can get them for a couple bucks at any store. Battery type 2032. Buy three, and throw an extra one in the glove box. Don't know why there is so much confusion about this. Well, I guess misinformation spread by uninformed dealers doesn't help. |

After I had my new car for a month, the key fob started to have problems. They changed the battery and still gave me problems. Turned out the comfort access module needed to be replaced altogether.

Now let's suppose you have 2 M3's, one with CA and one without. So if I drive the M3 with CA, can I bring along the fob from the other, non-CA M3 and plug it into the slot and recharge the battery without driving the non-CA M3.
This keeps me up at night..."What if....?" |

I had the dealer replace mine under warranty. And, no, they didn't know that the Comfort Access key had a replaceable battery.

What Kind Of Sa Is That?!?
Has That Person Seen Any Of The Bmw Key Fobs Before?!? It's A Typical Case Of Lacking Of Basic Analytical Thinking. Simply Ask, I Wonder How The Key Fobs Could Be Charged, Since There Aren't Any "charging" Contact Terminals On It.. What A Joke... |

If you have an electric toothbrush, have a look at it. No metal contacts for charging. Google "Inductive charging". I think perhaps your "basic analytical thinking" is somewhat lacking.... The non-comfort access FOB WILL indeed charge, when inserted into the dashboard. The comfort access FOB will not.
