An electronic lock includes a locking mechanism and a control device. The locking mechanism includes an electronic driving module, a deadbolt, and a turning-piece module configured to be driven by the electronic driving module or to be manually operated to rotate among a first position, a second position and a third position, and to drive the deadbolt to move while rotating. The control device includes three Hall sensors surrounding a rotation axis of the turning-piece module, a magnetic component co-rotatable with the turning-piece module relative to the Hall sensors, and a control module. Each Hall sensor generates a sensing signal upon detecting the magnetic component. The control module is configured to activate a left-open setting or a right-open setting according to two sensing signals that are first received respectively from two of the Hall sensors without controlling the electronic driving module to drive the turning-piece module to rotate.
