I had this happen off and on. Do you plug in your key at all? The key battery may just be low so just plug it in while you drive and it should help.

comfort access
Did you ever solve the problem?
I have the same problem on my 2011 Z4. I can unlock and lock the doors by the key fob but the doors won"t unlock by touching the handles. I also have to put the fob in the dash to start the car. It is my understanding that if you have comfort access the key fob never has to go into the dash, that is why it has a replaceable battery instead of a rechargeable battery. |

- The CA key has a removable battery and does not charge in the key slot
- The key should get inserted into the key slot prior to going to a dealer for service. The key records the miles and service conditions. That is why the SA takes the key and sticks it in the little thingy on his desk. - If there is a CA module error or CA antenna error, a code reader will show it - Test the Other CA functions: Does the trunk/boot lid unlock? Does it allow you to lock your key in the car? (make sure you have another key!) jawolf... did this key ever work for you for CA? |

Its probably completely unrelated but I had the same problem a couple months ago.
I kept getting a "Increase battery discharge message" This usually causes my comfort access to not work. Guess it sees it as I am low on battery so to conserve battery, they turn off some functions such as comfort access. So I bought it to an independent shop and they said. 1.) My battery is like 5 years old and is just losing its charge 2.) The battery sensor was bad, dont remember what exactly the part was. It was giving an incorrect battery reading or something like that. No matter what my battery charge was, it read it as being low on battery. I replaced the battery and that battery sensory. My comfort access was fixed then. |

You are right on with this being a possibility. A weak battery will indeed result in non-vital systems being shut down. I was recently reading another thread about key-fob remote having a very short range. This is a Diversity Antenna issue. Now the part I am skeptical about... A couple people said their CA worked better after they changed the Diversity Antenna. I am not convinced the Diversity Antenna has anything to do with CA... but then again I continue to learn something new about these cars all the time. |

don't mean to hijack the the thread but my CA door lock is acting stupid lately. i would have to stand there holding my finger to the lines hoping it'll lock eventually EVEN though i put my key fob in the insert every ride.

The battery in the fob is a standard CR 2032 Lithium battery. Putting it into the dash slot doesn't charge it at all. It's the same battery that some of my wristwatches use so I have a few on hand to change them out. There is nothing rechargeable about them.

You can also do a load test by having a helper start the car while you look at the meter. The battery shouldn't drop more than 2V before the engine turns over.

If you have a reason to come up to South Bend, I can take a look at it for any error codes and perhaps swap in my CA module to test it out. I have an extra one on hand from another project that may work. PM me if you like Jim |

I have noticed a strange phenomenon yesterday with my CA as well. Sometimes (not all the times, I should stress out), when the car is locked and I try to open the passenger door, the locks would unlock as I'm lifting the handle but then lock back right as I pull the door open. So far, it has happened more so on the passenger side than the driver side (almost 2:1 ratio). And repeating the process doesn't help either.... it unlocks when I pull up then locks right back when I pull the door open. Very strange.
After trying a few times persistently, I just resort to pressing the unlock button on the remote and it fixes the issue. I have no problems with the trunk or turning on the car so far, so it must be something with the door modules. I will have to take it to the dealer I guess... sigh |

I really appreciate your input and offer to help. I am not sure when I will get there again but I will keep your offer in mind. I was actually there in the fall with the Indiana BMW club, they went to the Chocolate factory. I live near indianapolis.
