The Prison Key is a collection of metal keys on a hoop. Accordingly, it was created to aid imprisoned people, though it ultimately went unused.
In gameplay, the player can collect the Prison Key during different Missions in certain areas. For then to obtain it, the player must use the ID points earned from completing the Mission where the Prison Key was picked up to identify it on the identification screen.
