Concur. It takes a minute to replace the battery and off u go. Actually works better than it did before in terms of retaining data when I go into the shop.

Mystery of CA battery replacement

I put mine through a wash. Stupid but happened to others also. Although it still works (outstanding), I knew water must have gotten inside and it will rotten the battery and others if I did not dry it up. After looking at the pictures in the owner, I took the key cover off (be brave, you will not break it). Sure enough, water inside. I took the battery out and then blew dried everything. After replacing it, it did not work. Nothing was mentioned in the manual that after you took the battery out for too long or after the battery is dead, it loses its memory and it must be sync up with the car again. All I did was to take my good key with the dead one into my car. Start the car and the dead key learned the setting again. Everything works great since then. A trip to the dealership is crap.
In the manual, it say if you key malfunctions, assuming you are stuck with only one key with you, pull the real key out, unlock the door. Point the dead key to the key mark on the steering column (yes, for 2012 5 Series, no key hole to put in the fob any more). Start the car and it should start. Assuming you have a good battery in the fob, it should pair up with the car again.

Well, my 97 E63 with CA has a replaceable battery fob. I would guess between then and now, BMW is using disposable battery for the CA key.

Correction. I meant 2007. I doubt they had CA in 97.

Sorry.

Definitely crap, although I specifically recall the sales advisor telling me I had to charge the key fob when I bought it, and I have been periodically driving with it in the receptacle in the car to try and 'charge it,' until I read on here.
Unfortunately, I didn't read on here until I dropped it off and told the service advisor about it. They didn't ask, but charged me $12 for the battery to put a new one in. He thoughtfully 'didn't charge me any labor.' That's great, since it took all of 20 seconds.

Just replace it yourself with the battery from RadioShack, Amazon, or lots of other places. It's a very common size battery.

Mein Auto: 2011 328i xDrive
Timely thread. the past week my CA wasn't working outside of the car unless I pulled the fob out of my jacket pocket. Then this weekend when I started the car I got the key/battery symbol indication. Planned on changing the battery myself, however, I was in the area so stopped by the dealership and assuming it was covered (hadn't seen this thread) ask them to change it. I did ask if it was covered and was told "Of course; but we can't wash your car because technically we're not taking it in for service". My dealership only washes cars on Saturdays; unless the car is in for service.

Told me 20 mins; in reality it took 50 (must have had to run to Radio Shack for a battery :-) ). But replaced and good as new.

Lol, order a battery shipped to your door from Amazon (or equivalent). It takes longer to open the packet than install the battery in the fob. I already had one in my battery box.

i had my 07 E63 with CA since late 06. I remember replacing the battery twice, once on each key. Go eBay. Each battery cost you around $1.

My service guy told me I had both a rechargeable and replaceable in mt 2013 CA fob!! Plug it in every once in awhile to charge. MMMMmmmm

My F25 w/o CA doesn't have a fob slot so it must be a replaceable battery in it.

My CA access key battery lasted nearly three years until I got the dash warning. I was never under the impression that it was "recharged" while in-service as some of us actually read the owner's manual.

I'm still wondering which CA, Orange County BMW dealership gave the false advice (were they intending to charge for this service?), although I suspect which one it is.

Let's make a "pact," and expose stupid and/or dishonest dealerships...a deal?

BTW, having turned in a fully equipped E92 (with CA) for my "bare bones" E90, I sincerely miss CA. THIS WON'T HAPPEN AGAIN.

I don't think that they were intending to charge for the service. I think that the particular service guy didn't know what he was talking about and rather than admit it decided to stick to the "procedure" and admit the car for service (which was on their dime) to cover his own tail. I don't know what (if any) repercussions there were from me talking to the service manager, but I guess we'll see what happens when I take my car in for its next scheduled service in a few weeks. I hesitate to slam a dealership for one miscue: if it becomes a pattern though I'll be glad to say.

I go to OC dealer as well. It is more ignorant than they try to slam you for an extra 12 bucks. That's why I always take their advice with a grain of salt.

I guess they're entitled to one screw up. During one service event with my prior Mercedes S320, my SA said that all my "automatic door closing actuators" needed replacing. VERY EXPENSIVE. The only problem was that my model car didn't have this option. I told the SA that they were welcomed to install them...but I wasn't going to pay. Quite "red faced."

Oh yes. A Toyota SA tried to tell me it was time to replace the cabin filter on my P/U. My answer was where do you put them because my p/u does not have cabin filters. Oh we'll. I don't blame them. I blame the dealership. Local Lexus dealer is notorious trying to push not in service schedule services. They called those dealer recommended services. At least with bimmers, service is included for 4 yrs.

Noted. If they are a Bimmerfest sponsor, I'd not be inclined to do it for this infraction...especially if they weren't going to charge for it. I'm not inclined to 'slam' sponsors unless we observe repeated problems that can't be resolved with the dealership through reasonable negotiations.

Mein Auto: Volvo
I recently bought a 2009 328i wagon. It has those ridges on the door handle and the battery in the key-fob is 2032 non-rechargeable. If i red the manual correctly, the non-comfort access have rechargeable battery and comfort access have regular battery. When I try to open the door with key in pocket, it simply does not work. And inside the car when I press the ignition button twice without the key in the slot the car displays the a "Key with diagonal line" on it. I have changed the battery with new one but nothing so far. o I need to take it to dealer to reprograme it?

Thanks.
