Weapon Pickup and change

I'm using the code below to "pick up" an object with in trigger. I'm using the SetActiveRecrusivily to activate and deactivate objects. But now, when my "Secondary" is activated after "pick up", I cannot activate my primary when key (1) is down. Please help

 var hasRocketLauncher = false; // tells if you have a rocket launcher
 var hasMachineGun = false; // tells if you have a machine gun
 var ammoClips = 1; // tells how many ammo clips you have
 var rockets = 10; // tells how many rockets you have
 var Primary : GameObject;
 var Secondary : GameObject;
 
 private var inTrigger = false;
 private var object: Transform;
 
 function OnTriggerEnter(other: Collider){
   inTrigger = true; // the player entered the trigger
   object = other.transform; // save the object transform
 }
 
 function OnTriggerExit(other: Collider){
   inTrigger = false; // the player left the trigger
 }
 
 function Update(){
   // if player inside trigger and F pressed:
   
   if (inTrigger && Input.GetKeyDown("f")){     
     switch(object.tag){
       case "MachineGun": 
         hasMachineGun = true; // enable switching to the machine gun
         Destroy(object.gameObject); // destroy the picked object
         Primary.SetActiveRecursively(false);
       Secondary.SetActiveRecursively(true);
       if(Input.GetKeyDown("1")){
       Primary.SetActiveRecursively(true);
       Secondary.SetActiveRecursively(false);
       }
         break;
   
       case "RocketLauncher":
         hasRocketLauncher = true; // enable switching to the rocket launcher
         Destroy(object.gameObject); // destroy the object
         break;
       case "AmmoClip":
         ammoClips++; // increment ammo clips
         Destroy(object.gameObject);
         break;
       case "Rocket":
         rockets++; // increment rockets
         Destroy(object.gameObject);
         break;
     }        
   }
