If you’ve ever lost or forgotten your PlayStation 4 key, there’s a good chance that you can restore it using the PlayStation Network. This process is called “restoring a purchase.” To do this, you’ll need to create an account on the PlayStation Network and select the game or title that you want to restore. Once you’ve chosen your game or title, click on the “Restore Purchase” link. Once you’ve clicked on the link, you’ll be taken to a page where you’ll need to enter your PS4 key and other information about your purchase. After filling out all of these details, you’ll be asked to confirm your restoration. Once you’ve confirmed your restoration, click on the “Restore Purchase” button. You’ll now be able to play your restored game or title again!
