A LOCK CORE WITH AN ALARM INCLUDES A SHELL, AN INNER ROTARY MEMBER, A PLURALITY OF LOCKING PIN UNITS, AN ALARM-ACTUATING UNIT AND AN ALARM- STOPPING UNIT. IN USING, A CORRECT KEY IS INSERTED IN THE INNER ROTARY MEMBER SO THE SURFACE OF THE KEY CAN TRIGGER THE ALARM-ACTUATING UNIT TO LET THE ALARM IN A LOCK SOUND OUT. ROTATION OF THE KEY FOR A CERTAIN ANGLE CAN ROTATE THE INNER ROTARY MEMBER TO UNLOCK THE LOCK AND ALSO STOP THE ALARM. IN CASE A WRONG KEY IS USED BY A THIEF TO INSERT IN THE KEY HOLE BUT IMPOSSIBLE TO ROTATE THE INNER ROTARY MEMBER TO UNLOCK THE LOCK, THEN THE ALARM WILL SOUND OUT AFTER THE PRESET TIME (3 - 5 SECONDS) IN SUBSEQUENCE OF INSERTION OF THE WRONG KEY, FRIGHTENING A WOULD-BE THIEF.
