A dial and sleeve type combination lock is provided with a shift mechanism for moving the sleeves out of coupling engagement with the dials for changing the combination of the lock. The shift mechanism includes a rotary actuator mounted coaxially with the sleeves and having a portion of its periphery extending through an opening in the face plate of the lock. When the lock is on combination, the actuator can be rotated to move the sleeves out of coupling engagement with the respective dials by a camming action.
