scripting SetActive(true_false)?

Hey guys i have a problem with getting a deactivated gameobject to be reactivated

When i enter my atv everything works fine accept for the player it is still in the scene but turned off. my exit script can`t find it when i press F so how can i fix this?

 using UnityEngine;
 using System.Collections;
 
 public class Exit_ATV : MonoBehaviour {
 
 
     public GameObject Player;
     public GameObject ATVplayer;
     public GameObject ATV;
     public GameObject Trigger;
     public GameObject TriggerATV;
 
     // Use this for initialization
     void Start () {
         Player = GameObject.FindWithTag("Player");
         Player = GameObject.Find("Player");
         ATVplayer = GameObject.FindWithTag("ATVplayer");
         ATV = GameObject.FindWithTag("ATV");
         Trigger = GameObject.FindWithTag("Trigger");
         TriggerATV = GameObject.FindWithTag("TriggerATV");
     }
 
     // Update is called once per frame
     void Update()
     {
         if (Input.GetKey(KeyCode.F))
         {
             Player = GameObject.Find("Player");// Here is the problem! Player cant be found becouse it is set to SetActive(false) by my enter atv script
             Player.SetActive(true);
             ATVplayer.SetActive(false);
             ATV.SetActive(true);
             Trigger.SetActive(true);
             TriggerATV.SetActive(true);
 
         }
     }
 }
