Ignore Raycast not detecting collision??

I have a collider around a door detecting when the player is close enough and then showing a GUI. I have a gun that uses raycast so I put it on ignore raycast but it then ignores the collision. When I put it back to default it works fine. Is there a fix or should I just come up with a different solution?

 #pragma strict
 
 var theDoor : Transform;
 var theGUI : GUISkin;
 var doorIsClosed = true;
 var inZone = true;
 
 
 function OnTriggerEnter (theCollider : Collider)
 {
     if(theCollider.tag == "Player")
     {
         inZone = true;
     }
 }
 function OnTriggerExit (theCollider : Collider)
 {
     if(theCollider.tag == "Player")
     {
         inZone = false;
     }
 }
 
 function OnGUI ()
 {
     GUI.skin = theGUI;
     if(inZone && doorIsClosed)
     {
          GUI.TextField (Rect (Screen.width/2 - 200, 500, 400, 40), "Open with O");
     }
     if(inZone && !doorIsClosed)
     {
          GUI.TextField (Rect (Screen.width/2 - 200, 500, 400, 40), "Close with O");
     }
 }
 
 function Update () 
 {
     if (Input.GetKeyDown(KeyCode.O) && doorIsClosed && inZone)
     {
         DoorOpen();
     }
     if (Input.GetKeyDown(KeyCode.O) && doorIsClosed == false && inZone)
     {
         DoorClose();
     }
 }
 
 function DoorOpen () 
 {
     theDoor.animation.CrossFade("Open");
     yield WaitForSeconds(1);
     doorIsClosed = false;
 }
 
 function DoorClose () 
 {
     theDoor.animation.CrossFade("Close");
     yield WaitForSeconds(1);
     doorIsClosed = true;
 }
