Door key scripting problem

Ok, so I know there are loads of examples here on unity answer but i cant for the life of me make anything work. So I want to make a door open after I found the key. I know that I have to access one script from another but i cant do that This is the code from my door:

 var open : boolean;
  var enter : boolean;
 
  var defaultRot : Vector3;
  var openRot : Vector3;
 
 function Start(){
 defaultRot = transform.eulerAngles;
 openRot = new Vector3 (defaultRot.x, defaultRot.y + DoorOpenAngle, defaultRot.z);
 }
 
 //Main function
 function Update (){
 
 
 if(open){
 //Open door
 transform.eulerAngles = Vector3.Slerp(transform.eulerAngles, openRot, Time.deltaTime * smooth);
 }
 
 if(Input.GetKeyDown("e") && enter && GetComponent(Apanharchave).hasKey){
 open = !open;
 
 }
 }
  
     icon = Resources.Load("abriraporta");
 
 
 function OnGUI(){
 if(enter){
 GUI.Label(Rect(200, 500, 1000, 200), icon);
 }
 }
 
 //Activate the Main function when player is near the door
 function OnTriggerEnter (other : Collider){
 if (other.gameObject.tag == "Player") {
 enter = true;
 }
 if (open){
 enter = false;
 }
 }
 
 //Deactivate the Main function when player is go away from door
 function OnTriggerExit (other : Collider){
 if (other.gameObject.tag == "Player") {
 enter = false;
 }
 }

And this is the script of my key

 var hasKey :boolean= false;
 var icon : Texture2D;
 
  var enter : boolean; 
 
 
 function Update ()
 {
     if(Input.GetKeyDown("e") && enter)
     {
         Destroy (gameObject);
         hasKey=true;
     }    
 }
 
 icon = Resources.Load("apanharobjeto");
 
 function OnGUI()
 {
     if(enter)
     {
         GUI.Label(Rect(200, 500, 1000, 200), icon);
     }
 }
 
 function OnTriggerEnter (other : Collider)
 {
     if (other.gameObject.tag == "Player")
      {
         enter = true;
     }
 }
 
 function OnTriggerExit (other : Collider)
 {
     if (other.gameObject.tag == "Player") 
     {
         enter = false;
     }
 }

I have the tag Player on the player, the tag Door on my door and the tag Key on my key. Thanks in advance!
