15. Enter the factory Master Code #12345678. The keypad will flash blue, and the handle will retract the latch.
16. Mark a vertical line on the door jamb half the door thickness away from the door stop. This gives the centre
line of the strike plate. Align the strike plate template with the height line, with the arrow heads aligned with the
centre line. Mark the fixing holes, and draw around the apertures for the latchbolt and the deadbolt. Chisel out the
latch aperture to 12mm (1/2”) deep, and the deadbolt aperture to 22mm (7/8”) deep. Fix the strike plate with the
top screw only and gently close the door. Ensure that the latchbolt enters its aperture easily and holds the door
without too much play. When satisfied, draw around the final position of the strike plate, remove it and cut a
rebate to allow it to fit flush to the surface. Re-fix the strike with both screws.
