Why won't my object lerp?

Here is all my code:

 using UnityEngine;
 using System.Collections;
 
 public class FlashlightTurn : MonoBehaviour {
 
     public float lookSensitivity;
     public float lookSmoothDamp;
     public float lookSpeed;    
     public Transform camera;
     public Transform player;
     public float cameraPan;
     public Transform cam;
     
     private float yRotation;
     private float xRotation;
     private float currentYRotation;
     private float currentXRotation;
     private float yRotationV;
     private float xRotationV;
     private Quaternion lookForward;
     private Vector3 lookLeftLimit;
     private Quaternion fromTo;
 
     void Start () {
         
         lookForward = transform.rotation;
        // lookLeftLimit = new Vector3(0,130,0);
     }
     
     void Update () {
         if (!Input.anyKey)
         {
             yRotation += Input.GetAxis("Mouse X") * lookSensitivity;
             xRotation -= Input.GetAxis("Mouse Y") * lookSensitivity;
 
             xRotation = Mathf.Clamp(xRotation, -30, 30);
             yRotation = Mathf.Clamp(yRotation, -50, 30);
 
             currentXRotation = Mathf.SmoothDamp(currentXRotation, xRotation, ref xRotationV, lookSmoothDamp);
             currentYRotation = Mathf.SmoothDamp(currentYRotation, yRotation, ref yRotationV, lookSmoothDamp);
 
             transform.localRotation = Quaternion.Euler(xRotation, yRotation, 0);
             fromTo = Quaternion.Euler(xRotation, yRotation,0);
             
             if(yRotation < -47)
                   player.transform.Rotate(-Vector3.up * Time.deltaTime * cameraPan);
             else if(yRotation > 27)
                   player.transform.Rotate(Vector3.up * Time.deltaTime * cameraPan);
             
             if(xRotation < -27)
                   cam.transform.Rotate(-Vector3.right * Time.deltaTime * cameraPan);
             else if(xRotation > 27)
                   cam.transform.Rotate(Vector3.right * Time.deltaTime * cameraPan);
 
         }
         if(Input.GetKeyDown("w")|| Input.GetKey("s") || Input.GetKey("a") || Input.GetKey("d"))
             transform.rotation = Quaternion.Lerp(transform.localRotation, lookForward, lookSpeed * Time.deltaTime);
             
     
     }
     
 }

Forget about most of the code. Its just there in case you need to look at it. The code i need help with is the last if statement. Thanks
