IR signal will play a different command

Hi,
I am quite new with launchpad and Energia and I am trying to code that when I point with my remote control at the IR receiver my two Servo motors will go to a specific point and repeat over and over again, but when I press the same button again they will stop moving. So I got 5 buttons on my small remote control and I want them to each play a different command. I already made something, but the problem with that is that the servo's won't stop moving. Can someone please help me with this? :)

• #include <IRremote.h>
  #include <Servo.h>
   
  Servo motorA; //the name of the servo motor
  Servo motorB;  
  IRrecv irrecv(7); // the receiver connected with pin 7
  decode_results results; 
   
  void setup()
  {
    Serial.begin(9600);  //serial communication
    irrecv.enableIRIn(); // start the receiver
    pinMode(GREEN_LED,OUTPUT);
    digitalWrite(GREEN_LED,HIGH);
    digitalWrite(RED_LED,HIGH);
    motorA.attach(13); // connect the servo with pin 13 and 10
    motorB.attach(10);
  }
   
  void loop() 
  {
    if (irrecv.decode(&results)) { 
      Serial.print("IR code: ");
      Serial.println(results.value, HEX); 
   
      int key = results.value % 16;  
      Serial.print("key: "); 
      Serial.println(key); 
   
      switch (key)
      {
        case 2:
          doKey2();
          break;
        case 3:
          doKey3();
          break;

          doKey4();
          break;
        case 7:
          doKey7();

          break;
    }
