Tools and Materials You’ll Need

Before installation begins, gather these common tools:

• Screwdriver (Phillips and flathead)

• Power drill

• Hole saw kit (for new installations)

Step 1: Remove the Old Lock (if applicable)

If you’re replacing an existing door lock, unscrew and remove the handle, latch, and strike plate.

Step 2: Mark and Drill New Holes (for new doors)
