2011 335d: key fob dead and no CA

Manually open door with key and put fob into the ignition and dead. Waited a few hours and everything is normal but need to reset the clock from zero to current time. This is the second time this has happened, don't want to be stranded somewhere with my wife and son. My key fob does not allow me to change the battery. Anyone experience this? If so what was the fix? Any advise is helpful. Thanks all

The car not starting, with the fob in the ignition slot, has nothing to do with the fob battery. The fob battery is used for the remote buttons, not starting the car - the plastic emergency keys do not contains a battery at all, just the transponder.

It sounds like you have an issue with power to the car. The first thing i would look at, are the lead cables at the battery.

When the car starts loosing the time of day its usually the battery(in the car)
dipping to a voltage to low to support memory functions.(and that is stored in the car)
If and when you change the car battery.
You do not want anybody using battery back up on these
cars it will blow the OBD/instrument cluster fuse.
If you have comfort access you have to have a fob with a changeable battery.
If you do not have ca then you can try charging your key with a toothbrush or
other type of inductive charger, but that does not sound like what the problem is.
It sounds like the car battery.

Your battery is now about 6 years old...time to replace it. The fact that the clock does not hold time is one big indication that the IBS is shutting down systems in order to preserve enough charge to start the car!

Suspect the car battery or charging system is the problem area. Go to a qualified BMW mechanic and have it checked out.

Sorry I forgot to mention that I drove the car to the mall about 30 mins prior to this happening but the drive was only 5-10 mins each way and the last time I drove her was on Friday to and from work which is 25 miles each way. Thanks for all of the input, I'll have to have the battery and charging systems checked out. Will report back. Thanks again

I've owned the car for 4 years and not sure if the battery was changed before me but the battery checked out fine. The problem was the power distribution box and the wire cable in front of the box was discolored so both were changed. Fingers crossed and hope this is fixed, don't want to be stranded somewhere. Have a nice weekend everyone.
