Arduino uno wifi rev2 stuck inside loop

It might be a stupid question but I can't figure it out. While running the code below. I want to open the box when the code matches the code in API. This all works. I can even close the box afterwords. But then I am stuck inside my loop. after the box is closed I want the screen to say box closed and then I want the void loop() to start again. so my screen asks for a code again. I tried using break and exit but no luck so far. entire code:

/* hardware libraries*/
#include <Key.h>
#include <Keypad.h>

This is where the code get's stuck. It keeps on showing box opened press * to close. even when I press * and the box closes it keeps on saying this

while (boxOpenend) {

          lcd.clear();
          lcd.print("Box openend ,press");
          lcd.setCursor(0, 1);
          lcd.print(" * to close");

          myservo.write(0);// rotate the servo to open
          delay(175);

          char key = customKeypad.getKey();   // get the key pressed
          //value = value + String(key);

          if (key == '*') {
            myservo.write(90); // rotate the servo to lock
            value = "";                           // clear the string
            boxOpenend = false;

          }
          // box gaat terug toe maar ik blijf in deze loop zitten want lcd scherm blijft staan op "Box geopend , druk * om te sluiten
        }

      }

It might have a simple solution that I'm just not thinking of but it really bothers me!
