Opening and closing drawers with start and end points

Hey there guys, I'm having a fair bit of trouble with opening and closing drawers, with what i have at the moment when i open and close the drawers, they open and retract at different positions.. I don't know how to better describe this, so i have provided a quick Video demonstration to provide the answer I am looking for.

My current code:

 var start : Vector3;
 var end : Vector3;
 var opening : boolean = false;
 var closed : boolean = true;

 public var smoothTime : float = 0.1;
 public var maxSpeed = 8;
 public var openDist = 0.2;
  
 function Start ()
 {
     start = transform.position;
     closed = true;
 }
  
 function Update ()
 {
     if(opening && closed)
     {
         //transform.position = Vector3.SmoothDamp(origin, origin + transform.forward * openDist, velocity, smoothTime, maxSpeed);
         transform.position = Vector3.Lerp(start, start + transform.forward * openDist, Time.deltaTime * smoothTime);
         closed = false;
         end = transform.position;
     }
     if(!opening && !closed)
     {
         //transform.position = Vector3.SmoothDamp(origin, origin - transform.forward * openDist, velocity, smoothTime, maxSpeed);
         transform.position = Vector3.Lerp(end, end - transform.forward * openDist, Time.deltaTime * smoothTime);
         closed = true;
     }
 }

 function open ()
 {
     opening = !opening;
 }

I am trying to achieve a non animated script here, due to I just want to be able to add the script to the drawer and that's it, not have to make animations for each drawer i want to open/close
