Why has the key joint produced a wriggly crack along the surface?
The concrete has not been finished of flush with the top of the key joint section. It must be finished to the top of the KJ profile (or capping strip if it was used), not over it. Any concrete over the top level of the key joint will inevitably crack unevenly along the general direction of the joint.
