Remote control LCD

I have written this code for a remote controlled LCD and when I compile and upload it there are no errors, however when I tried to check if it was working nothing would show up on the LCD whenever I clicked a button on the IR controller. Does anyone have an idea as to why this is happening, if so I very much appreciate it. The code is below.

#include <IRremote.h>
#include <LiquidCrystal.h>

const int RECV_PIN = 7;
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
IRrecv irrecv(RECV_PIN);
decode_results results;
unsigned long key_value = 0;

void setup(){
  Serial.begin(9600);
  irrecv.enableIRIn(); 
  irrecv.blink13(true);
  lcd.begin(16, 2);
}

void loop(){
  if (irrecv.decode())
 
        if (results.value == 0XFFFFFFFF)
        results.value = key_value;
        lcd.setCursor(0, 0);
        lcd.clear();
        
  switch(results.value)
{
  case 0xFFA25D :
  {
    lcd.print("OFF");
    delay(1000);
    lcd.clear();
    break;
  }
  case 0xFF629D :
  {
    lcd.print("VOL+");
    delay(1000);
    lcd.clear();
    break;
  }
  case 0xFFE21D :
  {
    lcd.print("FUNC/STOP");
    delay(1000);
    lcd.clear();
    break;
  }
  case 0xFF22DD :
  {
    lcd.print("|<<");
    delay(1000);
    lcd.clear();
    break;
  }
  case 0xFF02FD :
  {
    lcd.print(">||");
    delay(1000);
    lcd.clear();
    break;
  }
  case 0xFFC23D :
  {
    lcd.print(">>|");
    delay(1000);
    lcd.clear();
    break;
  }
  case 0xFFE01F :
  {
    lcd.print("DOWN");
    delay(1000);
    lcd.clear();
    break;
  }
  case 0xFFA857 :
  {
    lcd.print("VOL-");
    delay(1000);
    lcd.clear();
    break;
  }
  case 0xFF906F :
  {
    lcd.print("UP");
    delay(1000);
    lcd.clear();
    break;
  }
  case 0xFF9867 :
  {
    lcd.print("EQ");
    delay(1000);
    lcd.clear();
    break;
  }
  case 0xFFB04F :
  {
    lcd.print("ST/REPT");
    delay(1000);
    lcd.clear();
    break;
  }
  case 0xFF30CF :
  {
    lcd.print("1");
    break;
  }
  case 0xFF18E7 :
  {
    lcd.print("2");
    break;
  }
  case 0xFF7A85 :
  {
    lcd.print("3");
    break;
  }
  case 0xFF10EF :
  {
    lcd.print("4");
    break;
  }
  case 0xFF38C7 :
  {
    lcd.print("5");
    break;
  }
  case 0xFF5AA5 :
  {
    lcd.print("6");
    break;
  }
  case 0xFF42BD :
  {
    lcd.print("7");
    break;
  }
  case 0xFF4AB5 :
  {
    lcd.print("8");
    break;
  }
  case 0xFF52AD :
  {
    lcd.print("9");
    break;
  }
}
}

Did you test the hardware with the example sketches from the LCD and IR library?
