For a one-piece door,

mounting hole:
• Insert a small phillips screw driver
into the small hole at the bottom of
the cover and gently pull outward to
loosen.
• Slide the cover down to remove.
Center the keypad at eye level against the selected
location. Mark 4-1/4" up the centerline from the bottom and

1/8" to protrude above surface. Position keypad on screw
head and adjust for snug fit.
With cover open so bottom mounting hole is visible, use a
punch to mark hole. Remove keypad and drill 1/8" pilot
hole. Replace keypad and complete installation with
