On the script where you save the level number add an additional if:

if(PlayerPrefs.GetInt("Level2Save") < currentlyFinished) // check if the current lock is lesser than what you're playing right now
    //If so, do the save.

That should prevent re-locking higher levels.

The only thing is, PlayerPrefs aren’t the safest way to store game progression data, unless you add some kind of checksum.

Edit:

You may also want to change your Start() method of the script above to something like this:

 void Start () {
     var _lock = PlayerPrefs.GetInt("NewLevel2Save");
     for(int i = _lock; i > 1; i--)
        GameObject.Find("lock"+i).GetComponent<Image>().enabled = false;
 }

Or better yet, store a refence to these Images somewhere and just access them.
