Personal settings, Trip meter, Time, etc resetting

[daytonatrbo]

Could this possibly be caused by a dying key battery?

My wife's key keeps giving her battery warnings on the dash when she starts our 2009 35D. Twice in the last couple of months the date, time, and trip meter settings have been reset when using her key.


Are these related? Is the car not properly recognizing her key due to the week battery, or are the random resets indicative of a larger systems issue?



Any insight appreciated. I admit I didn't due much searching on the topic before posting. So if this is well documented, please feel free to berate me and flame me.
