When I use setblock to reset a filled chest the items aren't normal. You can't pickup them with shift. Also you can't detect the item in the inventorry.
setblock ~ ~3 ~ chest 0 destroy {Items:[:{id:minecraft:tripwire_hook,Slot:24,tag:{display:{Name:"Schlüssel"},ench:[{id:33,lvl:1}]}}]}Environment
Win 8.1u1, Java 8u5
Try this command.
