Hi, A friend wants to replace the door knob on the front door of her mobile home. We took off the old knob and its innards and can't get the new tongue mechanism to fit in to the edge of the door. Seems a mettle sleeve has been inserted in to the round whole in the edge which prevents the new lock mechanism to slide in from the side of the door. Should this mettle sleeve need to be removed and if so, how?
Thanks for any help or clarifying questions as I am sure I did not explain it very well.
