If you have confirmed that the existing holes are compatible with your new lock, please proceed to step 2 (skip step 1c).
If you need to make adjustments, go to
step 1c and find the closest match to each
aspect of your door on the Marking Template.
Tear off the Door Checker (pages 56) and follow the guidelines on both sides to
measure each aspect of your door and frame. There are some cases when existing
holes cannot be adjusted to be compatible.
Please do not drill any holes until you confirm that your door is compatible.

shape with solid outlines (23/4”), or the one with dashed
outlines (23/8”).
