You gotta have an e-reader and swipe the card. And you had to beat all other 69 trainers so you can fight the 70th trainer there. That's the only way to open that door.

A trainer is behind the locked door. You need and e-reader to open the locked door.

If you talk to the guy next to the computer in the Petalburg City Pokecenter and tell him 'MYSTERY EVENT IS EXCITING', a new option at the start of the game called Mystery Event. If you do this with a friend that also has Mystry Event, the door in Mossdeep will open and you will battle a guy or a girl (I think it's random...) with 3 pokemon...and you can only use 3 pokemon. I think they have like level 70 pokemon...but I'm not sure because I haven't done it yet...but I know thats how you open the door!

Behind the locked door is...THE 70TH TRAINER!!!! *dramatic music* You open the door through a Mystery Event link-up with the E-Reader after it scans a trainer E-card.
