Whats wrong in my code or logic, please help!,Hi everyone, i have a problem with a door key situation:

I want to collect a key and when the player collects the key, the player should be able to open a door ontrigger enter.

here is my script

public class Key : MonoBehaviour {

 private void OnTriggerEnter(Collider other)
 {
     if(other.tag == "Player")
     {
         Player player = other.GetComponent<Player>();
         player.CollectKey();
         player.OpenDoor();
         Destroy(this.gameObject);
     }
 }

}

Player script:

 private void OnTriggerEnter(Collider other)
 {
     if (other.tag == "Lava")

         Destroy(this.gameObject);

     if (other.tag == "Door" && _canOpenDoor == true) 
     {

         Debug.Log("Hello");
         Destroy(other.gameObject);
     }

 }

 public void Shoot()
 {
     if (Input.GetMouseButtonDown(0))
     {
         Instantiate(bulletPrefab, new Vector3(transform.position.x +1, transform.position.y, 0), Quaternion.identity);
         
     }
 }

 public void CollectKey()
 {
     keyIsCollected = true;
     uimanager.UpdateCoins(keyIsCollected);
 }

 public void OpenDoor()
 {
     _canOpenDoor = true;
 }

},
