Think of the ship lock as an hotel/concert bracelet. As soon as you sortie the event map with your fleet, you receive a color specific one in case you had none. The thing is you can only receive one bracelet per ship and you can't change it.

If you choose easy difficulty you get free pass it doesn't matter the bracelet color you have (however you still get a bracelet if any of your ships had none), but if you choose normal or hard difficulty you need a specific bracelet to sortie in that map.
