An electronic lock device includes a lock mechanism, an actuation mechanism that actuates the lock mechanism, and a control unit including a processor and a current detection module. During an operation in which the actuation mechanism is activated to start switching the lock mechanism from an original state to an intended state, the current detection module continuously detects an amount of electric current flowing through the actuation mechanism. When the amount of electric current is greater than a predetermined threshold, the processor controls the actuation mechanism to switch the lock mechanism back to the original state, and deactivates the actuation mechanism.
