Need help making Resident Evil style quick turn

My game has fixed camera angles similar to the early resident evil titles and I've been having trouble creating a quick turn action. I got some code that I thought would work but my character barely rotates if at all.

My Code:

 private Coroutine LookCoroutine;
 [SerializeField]
 private float quickTurnTime = 5f;

 void Update()
 {
     if (Input.GetKeyDown(KeyCode.Q) && isWalking == false)
     {
         StartRotating();
     }
 }

 public void StartRotating()
 {
     if (LookCoroutine != null)
     {
         StopCoroutine(LookCoroutine);
     }

     LookCoroutine = StartCoroutine(LookAt());
 }
 
 private IEnumerator LookAt()
 {
     Vector3 rot = transform.rotation.eulerAngles;
     rot = new Vector3(rot.x, rot.y + 180, rot.z);


     float time = 0f;

     while (time < 1)
     {
         transform.localRotation = Quaternion.Lerp(transform.localRotation, Quaternion.Euler(rot), Time.deltaTime * time);

         time += Time.deltaTime * quickTurnTime;

         yield return null;
     }
 }

Would appreciate some feedback on how to make this work and if it can and should be done another way.
