Per my knowledge roof rack are dealer-installed, so the records might not always follow.
I have bunch of old racks that I collected over the years and few of them had locked locks with no keys. All it took was flat screwdriver to insert in the slot where the latch was holding and it popped out. Once I had the rack open, the locking ring was easy accessible to remove the old lock and install new one.
