I’ve just bought a ‘11 pathfinder and the bonnet release isn’t working, I’m guessing the cables snapped? What’s the easiest way of getting into the mechanism to get it open? 
 

The usual way to release a bonnet is going through the grill area, either try releasing it with a screwdriver poked through but watch the radiator, etc

Alternatively, try removing the grill to access the latch mechanism
