Befor you do the locker thing, you have to go to the information center, talk to clerk and when she leaves Peter W. goes behind the counter and inspects a surviellance monitor. The bottom right screen shows Graham O. aproaching and unlocking his locker and the locker number is indicated on the screen and that's the # you click on after you put the key in the lock. It should open. The correct locker is indicated by a hot spot.
