Sliding doors can no longer be opened from the inside

Moin together, the sliding doors of my space tourer can no longer be opened from the inside. The kids we have torn off the yellow pin of the child safety guard on both sides. I fear that the lock may have to be completely new on both sides or can it be placed differently on “duration open”? Otherwise, only the exchange of the locks would remain for me, the side cladding can be solved at least very easily after my first attack. VG
