MC mentions forgetting his locker combination early in the game, but all the lockers pretty clearly have key locks in the art, and there are no other references to locker combinations after MC gets the master key. It would be a pretty simple fix to change the tex to say MC lost his locker key.
It's a master key, and most lockers that have a dial combination also have a keyhole for a master key, where the student doesn't receive a key. This is not a bug. Please do not open extraneous bug reports.
