Hi, need your professional support. Our daughter drives a Kia Sportage 1.6 GDI Built. 2015 On the vehicle the rear left door can no longer be opened. Presumably from the car dealership: rear lock is defective. Because of the high costs to be expected I myself tried to get to the causer. (see picture, was by the way a tip from the car dealership). Now I am at the end with my Latin. If someone has a tip like I come to the def. lock under the given circumstances, or how I get the door open? I am grateful for every hint. Thank you in advance Mfg have
