No power no lights won't start

[Rudy1]

My wife drove my truck to work the other day everything ran fine and started fine. When she went to leave work that day the truck would not start no lights no nothing. Checked the batteries and they were fully charged too. Does anyone have any awnsers? Thanks

Any light indicators on the dash display. Maybe a vehicle with a lock indicator? Could be the theft deterrent system and it has shut down everything.
