Owners/service Manual problems of the 2013 Chevrolet Spark

After setting the "child protection" on both rear doors because of my new grandbaby I no longer needed it since he was no longer a baby I decided to take "child protection" off. Doors still would not open from inside. Left door outside handle broke as well so it could not open at all. Having extended warranty I took it to dealership which was time for oil change and needing other problems repaired as well. Left door repairs were"handle separated"and "replaced outside handle" which warranty covered. Right door was declined coverage because it was "the clip for inside cable to handle had separated". Couldn't understand what the difference was? clip vs handle?? service consultant was puzzled as well? needless to say door still only opens from outside. Having manual locks figured I wouldn't have any problems in future. Never figured a "manual child protector" would cause any problems. Due to lack of funds door still is unrepaired. I know that in some incidents it only takes one split second between life and death. God forbid someone looses there life because of a split second too late. Maybe you could explain the difference and if others are having any problems as well.
