I've seen locking the seat belt on kids in boosters in various threads on here. Do you mean locking it by pulling it all the way out of the retractor and letting it go back, the way you do for carseat installs? I'm curious about this, because my car owner's manual makes it very clear that locking the seatbelt this way is ONLY for carseats, and that (non-harnessed) passengers are NOT to ride with their seat belt locked.
