If you shut your car off and put your key back in, chances are on startup settings are just fine.
If it happens multiple times, chances are the battery in your FOB is dead. Your car charges it every time you put the key in, and if the battery dies you could lose the settings since it would take a long time to recharge and read them.
Just as a reminder to avoid this turning into yet another thread where this issue is confused, only NON-Comfort Access fobs are charged in the slot. If you have Comfort Access, buy a CR2032 battery anywhere for $2-3 and see if that helps.
