Why does my SetSwingDoorLocked no effect?

[Raymond]

I try to use the key on it but it says " Cannot use this item away". My code is like this:

Code: (Select All)

void Onstart()
{
AddUseItemCallback("", "prisonkeylight_1", "mansion_3", "UsedKeyOnDoor", true);
}

void UsedKeyOnDoor(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("mansion_3", false, true);
PlaySoundAtEntity("", "unlock_door", "mansion_3", 0, false);
RemoveItem("prisonkeylight_1");
}

It doesn't have any errors it just doesn't seem to work. Did i put something wrong .
