Can't make an unlockable door

[1402News]

I've been trying all the solutions I can but nothing works! Here's my script.

void OnStart()
{
AddUseItemCallback("", "CSBedroomKey", "CSBedroomDoor", "UseKeyOnCSBedroomDoor", true);
}
void FUNCTION(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked(asEntity, false, true);
PlaySoundAtEntity("", "unlock_door", asEntity, 0, false);
RemoveItem(asItem);
}
