Trouble with unlocking cursor

I am having trouble with the cursor unlocking so that the user can click buttons. I have two objects using this same script. When the user presses E on the object, a panel will show with buttons. What should happen for both is that the cursor becomes unlocked so that they can click these buttons. This only works for one of these two objects, I can't figure out why.

Here's the code for the objects:

 void Awake()
     {
         lockMode = CursorLockMode.Locked;   
     }
     void Update()
     { 
         var distanceToPlayer = (player.transform.position - transform.position).magnitude;
         if (distanceToPlayer < 3)
         {
             AccessCheck();
         }
         if (CanAccess && (Input.GetKeyDown(KeyCode.E)))
         {
             Access();
         }
         if (OnPC)
         {
             lockMode = CursorLockMode.None;
         }
         if (OnPC && Input.GetKey(KeyCode.Tab))
         {
             Time.timeScale = 1;
             currentScreen.gameObject.SetActive(false);
             currentScreen = emptyScreen;
             TerminalNum = 0;
             screen = 0;
             OnPC = false;
             lockMode = CursorLockMode.Locked;
         }
         if (DisableA)
         {
             AlphaSpawner.gameObject.SetActive(false);
         }
         if (DisableB)
         {
             BravoSpawner.gameObject.SetActive(false);
         }
         Cursor.lockState = lockMode;
     }

The variable OnPC is set in the Access function, if that's important. I really just don't understand what's wrong? Is it because the second objects are a prefab? Should they be entirely unique?
