The original keys had removable slip coats over the keys, both on the ignition and door/decklid key. Reproduction keys, including some from GM, often have the slip coat molded into the key so it is not removable. This is not the correct way the keys would have came with the car in 1984.
The Fiero Store sells reproductions of the GM slip coats for key blanks.
I think most of the reason why people made so many sets of keys for Fieros is because they've probably experienced locking a key in the car or decklid and wasn't able to get either open for whatever reason. I know most every Fiero I've bought has strangely enough had crazy amounts of keys. My '88 Formula I bought had five sets....
Almost all GM products I have bought since 1978 had two sets of keys. The ignition keys have always had the black plastic molded onto the key and the door/trunk keys have been the bare metal. However my 86 Fiero came new with one molded plastic door/trunk key and one bare metal.
I worked for a Chevrolet dealer in 64 and 65, and all cars at that time came with 2 sets of keys. Each had a number stamped in a knockout plug in the head of the key. This was the key number. Many of the service men or new car salesmen would take keys home after servicing or demonstrating a car and new keys had to be cut, then later the originals would show up on the board. Occasionally the purchaser of the new car would get several sets of extra keys in addition to the 2 original sets.

I got the Fiero from my father who owned it for a couple of years....it had 2 sets of keys. He tells me that it came with one set when he purchased it.....the other set he found under the seat after he had had the car for about a year.
