Key On a Cabinet

[SilentHideButFine]

void OnStart()

{
AddUseItemCallback("", "Thekey", "TheDoor", "Thefunc", true);
}


void Thefunc(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("TheDoor", false, true);
PlaySoundAtEntity("", "unlock_door", "TheDoor", 0, false);
RemoveItem("Thekey");
}

try that!
