NPC's *Closing the doors

[MikeCobalt]

Does anybody here know how to get the NPC's to actually "Close" the doors once they are past? I have the relevant doors set to Lock default and on the cell lock list plus their owner is not present in the cell however the other NPCs that do have the key can walk through (That's good) but they always leave the doors open (Not Good). The mod I'm working on locked and relocking doors from the NPC's is crucial.
