I am doing a project that requires input from a keypad to be displayed on the lcd display.

lcd.print() displays in proper form, but when the I press characters on the keypad, they are overwritted as weird symbols.

Any help would be appreciated.

Here's the code:

void setup()
{
  Serial.begin(9600);
  Serial.println("LCD test with PWM contrast adjustment");
  pinMode(13,OUTPUT);
  analogWrite(6,Contrast);
  
  lcd.begin(16,2);
  
  pinMode(buzzer, OUTPUT);
  lcd.print(" Electronic ");
  Serial.print(" Electronic ");
  lcd.setCursor(0,1);
  lcd.print(" Keypad Lock ");
  Serial.print(" Keypad Lock ");
  delay(2000);
  lcd.clear();
  lcd.print("Enter Ur Passkey:");
  Serial.println("Enter Ur Passkey:");
  lcd.setCursor(1,0);
  for(int j=0;j<4;j++)
    EEPROM.write(j, j+49);
  for(int j=0;j<4;j++)
    pass[j]=EEPROM.read(j);
}
