Question type: Maintenance & Repair

Weird Start problem with my 2010 ML350 4matic, 38000 Miles.
Often when I turn FOB key to ON position no display light and no lights on cluster and car can't start. I have to take the key out, put it again and turn no lights, no cranking, so often have to do that a few times to start car. Sometimes car starts immediatelly and works normally, but often before cranking no lights on cluster, though when i start and turn off the car, cluster display lights appear normally. The second spare FOB key works the same. It happens more often when the car is parked for few hours, days or longer.
FOB Key batteries are recently replaced, locking and unlocking, panic and trunk button does work properly on both key fobs. The auxiliary battery reports dead and needs replacement
What may be the issue, and how to fix it?

Sometimes can take the battery cables off for about five minutes.it lets the computer drain out the bad and reset .after five minutes hook battery back up and try it then .if not and a check engine light is on try to get a scan from local automotive parts dealer .
