This may sound silly but have the key fob batteries replaced? Are the locks on the rear doors locked (button down)?

Using the key fob opens the front doors, the car starts. I tried to pull the rear buttons, it does not help.

Resolved:
remove the door trim;
from drill a map of the window regulator; unscrew and remove the glass;
remove the protective cover of the lock (one bolt and several latches);
remove the window card;
break the lock with pliers (piece by piece, carefully without damaging anything else, break off the pieces from the lock body);
when the mechanism is exposed, the lock will open.

then we unscrew everything else and change the lock to a new one.

some additional things, may be some one help’s:
after removing the panel, before breaking the lock, the following:
1 on the lock from the side where the cable of the outer handle comes in there is such a cover with latches (picture 1);
2. unfasten the latches;
3. There will be a threaded gear under it, this gear pulls the cable (picture 2);

This may be a solution, since judging by the information and design, the cable will unfasten and the lock will stop working. should help.
If not, then break it.
