I agree, the keypads could just be the manual option for sending the lockers to a location. Considering all the different little features the scrolls have, I wouldn't be surprised if someone could call a locker manually. However if Beacon was under attack, I'm sure someone would notice a bunch of lockers and shoot them out of the sky.
