Step 1 : Remove the old handle
Use a screwdriver to remove the existing handle, then clean the entire surface of the door, especially around and behind the handle. Take the old handle with you when shopping for a replacement. Compare the replacement with the one you have and try to find a new one that has the same mounting hole pattern.
Step 2 : Tape the template to the door
Tape the paper template that was included with the new handle to the lock area of the door. The template assures that you drill mounting holes in the correct location for the handle because you drill through it. Align as many of the holes in the template with the existing holes and then tape it to the door.
Step 3 : Drill new holes
Where they are needed, drill new mounting holes through the paper into the door. Keep the drill level, especially when you begin drilling into the other side of the door. Wear safety glasses to protect your eyes.
Step 4 : Assemble the lock and install it
Follow the directions to assemble the lock. When both halves of the assembly are in alignment, the handle turns freely, and the lock system works, tighten the mounting screws. Close the door and check the clearance between the inside latching handle and the old latch bar.
