It probably will help. But check the shoulder and the spine of the key blank (the edge opposite the bitting cuts) and make sure the blank is not hitting on part of the lock.
Have had to file down the shoulder part way, and/or file a little bit off a part of the key to stop the lock itself from blocking the blank, preventing it from leaving impressioning marks.
Also, make sure your blank is long enough! Several times I have had no marks, and using my pick, determined that I needed a six pin blank instead of a five pin blank.
