Install the Doorknob
Your storm door may include a template, which will help you determine where to drill your holes for the door hardware (Image 1). Drill the holes for your doorknob and lock, line up the knob and lock, and insert them into the holes (Image 2), beginning with the exterior pieces. Then insert the interior pieces, and screw them into place.
Deadbolt locks are sometimes provided with new storm doors. These locks are installed in the same way as standard doorknobs (Image 3).
