Pickup Script Problem

Hi!

I have a problem with my pickup script. I can't find anything wrong with my code so some help would be appreciated.

When you go over a trigger tagged, for example "Battery", a text pops up and when you press "E" it should go to your inventory. Everything works except it wont dissapear and go to the inventory. If I delete "if (Input.GetKeyDown(KeyCode.E))" it works fine, but I need that part of the code.

Does anyone know how to fix this little poblem?

 var pickupText : UnityEngine.UI.Text;
 var flashlight : Flashlight;
 var inventoryScript : Inventory;
 var pickupSound: AudioClip;
 var batteryInRange : boolean;
 var flashlightInRange : boolean;
 
 function OnTriggerEnter (other : Collider)
 {
     if (other.gameObject.CompareTag("Battery"))
     {
         batteryInRange = true;
         if (Input.GetKeyDown(KeyCode.E))
         {
             inventoryScript.batteries += 1;
             other.gameObject.SetActive (false);
         }
     }
     if (other.gameObject.CompareTag("Flashlight"))
     {
         flashlightInRange = true;
         if (Input.GetKeyDown(KeyCode.E))
         {
             flashlight.enabled = true;
             other.gameObject.SetActive (false);
         }
     }
 }
 
 function OnTriggerExit ()
 {
     batteryInRange = false;
     flashlightInRange = false;
 }
 
 function Update ()
 {
     if (batteryInRange)
     {
         pickupText.text = "[E]  PICK UP BATTERY";
     }
     if (flashlightInRange)
     {
         pickupText.text = "[E]  PICK UP FLASHLIGHT";
     }
 }
