Hide GameObject - Re-Apear after 5sec

Hi i have a problem, I tried every possible thing that i got in my head but i can't make it done. the thing is that, I can't disable object and enable object after 5sec. and theres this (read after code)

 var Animator : GameObject;
 var WpnHolder : GameObject;
 
 private var gui1 : boolean;
 private var doAnim : boolean;
 ///////////////////////////////
 function Update()
 {
     if(Input.GetKey(KeyCode.Space)&& doAnim)
     {
     Animator.animation.CrossFade("Climb");
     WpnHolder.active = false;
     yield WaitForSeconds (5)
     WpnHolder.active = true;
     }
 }

Yes i know that it can not be corountine update() but i tried this

 var Animator : GameObject;
 var WpnHolder : GameObject;
 
 private var gui1 : boolean;
 private var doAnim : boolean;
 ///////////////////////////////
 function Update()
 {
     if(Input.GetKey(KeyCode.Space)&& doAnim)
     {
     Animator.animation.CrossFade("Climb");
     WpnHolder.active = false;
     wait();
     WpnHolder.active = true;
     }
 }
 function wait()
 {
    yield WaitForSeconds (5);
 }
 
 

i can't figure it out,help please :)
