Intruders often gain entry to a home by kicking or ramming the door at the point of the lock, knowing that even a sturdy deadbolt will give way through the door jamb if the strike plate installation is weak. The deadbolt strike plate is a metal plate on the door frame that has a square or rectangular center hole; the deadbolt passes through this plate to secure the lock. Reinforcing the strike plate strengthens the level of security a deadbolt lock provides.
Things You'll Need
- Power drill
- Driver bit
- 3-inch wood screws
- Putty knife or utility knife
- Pry bar
- Steel building plate
- Wood chisel
- Drill bit
- 1 1/2-inch wood screws
Unscrew and extract the two standard screws that hold the strike plate to the door jamb, using a power drill with a driver bit.
Replace the extracted screws with two 3-inch wood screws. Drive in the screws with a power drill until the screw heads are flush with the strike plate. These longer screws reinforce the strike plate because they reach into the wall stud.
Loosen the interior trim on the door jamb with the strike plate, also known as the strike jamb. Slide a thin putty knife or utility knife between the trim and the wall. Cut through any paint holding the trim in place, sliding the putty knife up and down the length of the trim.
Pry off the trim from the interior side of the strike jamb using a pry bar. Take care not to damage the trim.
Place a steel building plate on the interior side of the strike jamb where you removed the trim. Position the steel plate so it lines up with the strike plate's location. Trace the outline of the steel plate on the jamb with a pencil.
Chisel out the wood within the lines marking the steel plate's perimeter to a depth of about 1/8-inch, matching the steel plate's thickness.
Hold the steel plate in position on the jamb, and drill pilot holes into the wood through the holes in the plate.
Drive 1 1/2-inch screws through the steel plate into the wood, using the power drill. Use 3-inch screws at the points where the plate connects to the wall stud.
Nail the interior trim back into place on the jamb.
