        the 4 keys are on the same matrix could be just the keyboard.

          or maybe a clean of the K/B socket with some isopropyl
          and a close inspection of socket for damage also

              Problem solved, thank you for help me to solve this, the problem was the trace from KB (MY5) to CN4 (Keyboard Con.)

                Now that's a weird one. Did it have a liquid spill by any chance? Anyway, kudos for fixing it.

                  Yes i think so... it seemed to caught some liquids and have been cleaned and then come to my store because the four keys do not work

                  It is my opinion.

                    I`m wondering how did you know that was the problem?
                    your talking about mV or you find it with the scope?
                    Just cook it! It's already broken.

                      With the help of shematics i tested all pads with multimeter on test diode from CN4 to keyboard controller, the one that does not have continuity was MY5 that goes to pin 44 of keyboard controller.
