A semitrailer cargo door locking system is described for use with a semitrailer cargo door having as part of its opening mechanism a rotatable handle which secured within a hasp mechanism comprising a rigid lower hasp and a swivelable upper hasp. The locking system includes a shackleless keyed lock having an internal bolt for engaging aligned holes provided in the upper and lower hasps, thereby preventing unauthorized opening of the cargo doors when in a locked state. The lock housing is provided both with a protective extension to minimize attempts to pry the lock, and with a tapered side wall to prevent removal by the application of a destructive torque applied by a wrench or other like device. The lock is further provided with a anchor line for either permanently or removably securing the lock to the cargo door. To provide the lock with the ability to be used with regulated loads, a means may also be provided to attach a sealing structure to the lock.
