if you havn't got adjustable hinges your door will need toe and healing,you will have to take beads out and repack the glass or panel thats in your door to make it square again,its not an easy task to do,you have to place a packer at bottom where hinges are the put glass or panel back in then on the top of the lock side put a few packers in until square then put packers down each side at top and bottom then should work fine.hope this helps
