Sony Interactive Entertainment America (SIE) has a policy in place that requires all PlayStation 4 games to be locked after a certain amount of time has passed. This policy is in place to protect the security of the system and prevent unauthorized access. The lock on a PlayStation 4 game is typically set at 10 days, but can be increased or decreased depending on the game. The lock is also automatically enabled if the game has been played for an extended period of time or if it has been used in conjunction with another PS4 game that requires a lock-out policy. If you are having trouble unlocking your PlayStation 4 game, please contact our customer service team at 1-800-853-4545 and we will do our best to help you out.
