Story locks are plot checkpoints that will not let you pass if you have not gained pertinent information from other routes. Trophy-wise, it doesn't matter if you actually are stopped by these locks when you're playing the game (as opposed to already having the information before hitting the lock in the first place).
The fifth lock is located via the following choices: Cyan / Ally / pass story lock 4 (see If I Told You You Had A Nice Antibody...) / Betray.
To bypass this story lock, you must play the following route: Magenta / Betray / Red (you don't have a choice) / Betray – i.e. you must first clear Dio's ending.
