A method for controlling security truck door lockers and a structure for controlling security truck door lockers are disclosed. A control device is configured to control electronic lockers respectively mounted on security truck doors by means of detecting the unlocked/locked status of the electronic lockers and changing or not changing their status accordingly, and then informing users of the locker's current status. The electronic locker includes a substrate, a fastener, a stopper, a micro switch, and a locker core. When a bolt of the door fastens the fastener, the stopper horizontally moves to contact a bottom of the fastener by means of controlling the operation of the micro switch, or the locker core drives an engagement portion to contact the fastener so that the fastener is fastened and the locker is locked.
