I agree totally with others who have reviewed this item that a photo of the working end of it would be appropriate.  Otherwise the key works great.  The key has the weight of a metal key, but when you look inside the slot, there is white plastic look to it, so not sure if it's really metal or if it's metal coated plastic.  Still considerably better than the original totally plastic key provided when freezer was originally purchased.  Time will tell!
