from my understanding, the 335i will automatically turn off no matter in what condition, drive, etc if it does not detect the ca-fob in the slot or inside the car for the matter. is this correct?

lastly since the ca-fob is not rechargable through the slot, what would happen if you are driving and the key runs out of battery or just fries so to say?

no.. the car wont turn off until YOU turn it off. do a search

If the FOB battery dies, the car will stay on until you turn it off. Once it is off, you won't be able to start the car unless you insert the key.

You will also get a "low battery" warning when the battery needs to be replaced.

In the instrument cluster. I've attached the page from the manual that talks about it. This is from the idrive manual, so nonidrive manual page # may be different.

Edit: Not sure about lifetime of each battery or battery type.
