This is my revised sketch, please check it out and see if I understood you correctly thank you so much.

// C++ code
//
int buttonState = 0;

void setup() {
  pinMode(5, OUTPUT);
  pinMode(10, INPUT);
  pinMode(7, OUTPUT);
  pinMode(1, OUTPUT);

  digitalWrite(5, HIGH);
  pinMode(5, OUTPUT);
  // BLOCKS LS. 3
}

    digitalWrite(2, HIGH);
    pinMode(2, OUTPUT);
    // POWERS MOTORS
    delay(6000);  // Wait for 6000 millisecond(s)
    // LS. 3 IS NO LONGER BLOCKED
    digitalWrite(5, LOW);
  }
