Create 2 seperate instances of the same prefab,create 2 Separate instances of the same prefab

Hello Everyone,

I'm trying to create 2 separate instances of the keypad prefab below.

The problem is that it doesn't matter on which one of them I tap, they both respond and show the same output.

My guess is that they both refer to the same script attached to the prefab and I don't know how to create 2 separate instances of the same script.

Here the script attached to them:

 using UnityEngine;
 using UnityEngine.UI;
 
 public class LockSystemScript : MonoBehaviour
 {
 
     public Text ScreenText;
     
     private int _taps;
     private Color _startColor;
     private AudioSource _clickSound;
     private RequestsManager _requestsManager;
     private Vector3 _screenCenter;
     
     private void Start ()
     {
         _taps = 0;
         _startColor = ScreenText.color;
         _clickSound = GetComponent<AudioSource>();
         _requestsManager = RequestsManager.Instance;
         _screenCenter = GetScreenCenter();
     }
     
     private void Update () {
         
         if (Input.GetMouseButtonDown(0))
         {
             Ray ray = Camera.main.ScreenPointToRay(_screenCenter);
             RaycastHit hit;
 
             if (Physics.Raycast(ray, out hit, 100) && hit.transform.gameObject.tag.Equals("Button") && _taps <= 3)
             {
                 ScreenText.text += hit.transform.name;
                 _clickSound.Play();
                 _taps++;
             }
             
             if (hit.transform.gameObject.tag.Equals("Submit"))
             {
                 _clickSound.Play();
                 StartCoroutine(_requestsManager.InputCode(ScreenText.text, ScreenText));
             }
 
             if (hit.transform.gameObject.tag.Equals("Reset"))
             {
                 _taps = 0;
                 ScreenText.color = _startColor;
                 ScreenText.text = "";
                 _clickSound.Play();
             }
         }
     }
 
     private Vector3 GetScreenCenter()
     {
         float screenX = Screen.width / 2;
         float screenY = Screen.height / 2;
         return new Vector3(screenX, screenY, 0);
     }
 }
