CharacterShop problem,Charactershop problem

Hi, i am currently working on a shop for my platformer, and everything works except the unlock button does not turn interactable when i have enough money. I have made a reset button that resets all playerprefs. If i have enough money and THEN press reset, everythings works perfectly. But the reset button are not meant to be in the final version. But if i press reset before i get enough money the button does not work. So i need a way to maybe refresh the scene and check if i have more money than the price of the item? Any suggestion is appriciated and if you have more questions just ask:)

Here the code:

using System.Collections; using UnityEngine; using UnityEngine.UI; using UnityEngine.SceneManagement;

public class ObjectBuyer : MonoBehaviour {

 public static int score;

 int isObjectSold;

 public int objectPrice;

 public Text text;
 public Text ObjectPrice;

 public Button buyButton;

 public Button selectButton;

 // Use this for initialization
 void Start()
 {

     score = PlayerPrefs.GetInt("PlayerCurrentScore");
     score = PlayerPrefs.GetInt("IsObjectSold");


 }

 // Update is called once per frame
 void Update()
 {


     isObjectSold = PlayerPrefs.GetInt("IsObjectSold");

     if (score >= objectPrice && isObjectSold == 0)
         buyButton.interactable = true;
     else
         buyButton.interactable = false;

     if (isObjectSold == 0)
         selectButton.interactable = false;



 }

 public void buyObject()
 {
     ScoreManager.AddPoints(-objectPrice);
     PlayerPrefs.SetInt("IsObjectSold", 1);
     buyButton.interactable = false;
     selectButton.interactable = true;
 }

 public void exitShop()
 {
     PlayerPrefs.SetInt("Score", score);
     SceneManager.LoadScene("Main Menu");
 }

 public void resetPlayerPrefs()
 {
     score = PlayerPrefs.GetInt("PlayerCurrentScore");
     buyButton.interactable = true;
     //objectPrice.text = "Unlock";
     PlayerPrefs.DeleteAll();

 }

},
