The utility model relates to an S-shaped key and a lock core, which consists of a lock core shell, a lock core, an S-shaped key, a blade group, a movable pin, a spring, an anti-drilling pin and a clamp spring. The interior of the lock core is located on the left, right and right sides of the blade, thus presenting a space with an S-shaped cross section. When the key is inserted, the S-shaped cross section of the lock core becomes longer and shorter. Driven by the key-shaped teeth, there is a certain dislocation between the inner and outer adjacent blades, so that the outer blade blocks the inner blade driving groove in turn, making it impossible for the outside to enter. So as to prevent other non-key objects from entering the blade drive slot, effectively prevent technical opening, and because the movable pin in the lock core reaches a certain thickness and strength, it is difficult to forcibly open it. The utility model effectively solves the defect that the common blade lock is easy to be illegally opened, and the structure is simple and reliable, which is very suitable for the public.
