This isn't really "lock picking" so we don't usually cover it here. These locks are also commonly used on high school lockers, so we don't discuss them here in order to not teach teenagers simple tricks on getting into people's lockers.
I suggest finding a youtube video that covers that kind of lock. They dont mind showing all those tricks.
