Off-Centered Holes

If you drilled a hole off center, your key will look like the key on the left. Hopefully, this illustration is exaggerated.

In this situation, you must cut the slot where the hole is. Do not center your slot on the key. As long as the slot is in the same position as the original hole, the key will function correctly. Remember to stay inside the lines when you cut. The slot should be slightly narrower than the diameter of the back rail pin that will fit into it.
