A lock core device based on matching the cross-sectional shape of a multiple key and a corresponding lock key, the lock contains a keyway, and the outer contour of the keyway is configured as a first section contour and a second section contour after superimposition, and its' a union outer contour. By adapting to existing keys with various cross-sectional profiles, the lock cylinder does not need to be manufactured separately according to the cross-sectional profile of the key, thus effectively reducing its manufacturing and inventory costs; A method for configuring a lock ball slot so that, in response to the deviation of the position of the teeth of the keys with different cross-sectional profiles, the teeth of the keys with different cross-sectional profiles can correspond to the lock ball slot for unlocking, thus ensuring stability and effectiveness during unlocking.
A lock core device configured for matching multiple key cross-sectional shapes, the lock core device being adapted for use with a first lock key with a first section contour and a second lock key with a second section contour different from the first section contour of the first lock key, the lock core device comprising:
A method of configuring ball slots of a lock core device, the method comprising:
