Program runs too often!

So my goal here is to run a servo when an IR (remote) signal is received. The problem is that whenever I use the remote, which obviously broadcasts the code quite frequently, the servo (the open() program) runs however many times the code is received, usually between 3 and 5 times. This is the part of the code that actually activates the open program when the remote button is pushed.

void loop(){
  keypad.getKey(); //not important for this question
  if (irrecv.decode(&results)){ //gets results
  Serial.println(results.value); //prints to serial monitor (useful for adding buttons)
 if (results.value == 554162470); //checks for results of the desired button
 {
   open(); //runs another program dealing with a servo
  }
}
}

Is there a spot in there to set a delay? As far as I know the ir library that I'm using doesn't have a debounce function.

try this

void loop(){
  keypad.getKey(); //not important for this question
  if (irrecv.decode(&results)){ //gets results
  Serial.println(results.value); //prints to serial monitor (useful for adding buttons)
 if (results.value == 554162470); //checks for results of the desired button
 {
   open(); //runs another program dealing with a servo
   delay(5000); //does nothing for 5 seconds
  }
}
}

Thanks for the reply! Tried that and it simply puts a 5 second gap between each that the servo runs, and it still runs 3-5 times.

You have an additional semicolon

 if (results.value == 554162470); //checks for results of the desired button

The following runs every time because of that.

 {
   open(); //runs another program dealing with a servo
   results.value = 0;
   delay(5000); //does nothing for 5 seconds
  }

Works great! thanks
