LocalRotation does not work

why LocalRotation does not want to work in this line  gmo.transform.localRotation = Quaternion.identity;

here is the script

 void Start()
      {
          rb = GetComponent<Rigidbody>();
      }
      void OnTriggerStay(Collider other)
      {
          if (other.CompareTag("Player"))
          {
            
             
                 invite = true;
                 rb.isKinematic = true;
                 rb.detectCollisions = true;
                 if (timeCount >= 2.0f)
                 {
                     
                     rb.isKinematic = false;
                     rb.detectCollisions = false;
                     transform.SetParent(other.transform, true);
 
                 gmo.transform.localRotation = Quaternion.identity;
 
                 BlazeIt = gameObject.GetComponent<HingeJoint>();
                     BlazeIt.connectedBody = targetJoint;
 
                     Debug.Log("Good");
                 }
                 timeCount = timeCount + Time.deltaTime;
 
             
 
 
          }
      }
 
     void Update()
     {
 
 
         if (invite == true)
         {
             if (Input.GetKey(KeyCode.T))
             {
                 transform.position = Vector3.Lerp(startMarker.position, targetTransform.position, timeCount);
                 gmo.transform.localRotation = Quaternion.identity;
                 // transform.DORotate(pos, duration, RotateMode.Fast);
             }
         }
         
 
        
 
     }
 
 }
