Level progression after collecting all coins

Hey y’all, still new to this and any help will be much appreciated!
I’m trying to setup a door in my 2D platformer to be usable after the player has collected the 5 coins in my level.
Here’s my current script;

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;


public class MoveScenes2D : MonoBehaviour
{

    bool openDoor = false;
    [SerializeField] private string newLevel;

    void Update()
    {
        if(ScoreManager.score = 5)
        {
            openDoor = true;
        }

    }


    void OnTriggerEnter2D(Collider2D other)
    {
        if(other.CompareTag("Player") && openDoor = true)
        {
            SceneManager.LoadScene(newLevel);
        }
    }
}

In ScoreManager, score is a public static int which tracks the number of coins collected. What am I doing wrong? D:
