Abstract No-rotation lock core consists of mainly program controlled balls, lock body, locking parts and key; and the lock body may be either mechanical control one or electromechanical control one. Only after the key and the program controlled balls reach preset contact condition, the mechanical or electromechanical stop release the controlling part. Unlike available locks, the no-rotation lock core with not be unlocking illegally, even if in case of taking out the lock core, and this makes the lock very safe.
