You can install the most expensive Grade 1 deadbolt on the market, but if your strike plate is secured with half-inch screws into soft wood, a single kick can still open your door. The strike plate is one of the most impactful — and overlooked — home security upgrades available.
The strike plate is the metal plate mounted to the door jamb that the deadbolt or latch bolt extends into when locked. The opening in the plate aligns with a mortise cut into the door jamb and usually a strike box behind it.
Most homes have a thin, stamped steel strike plate secured with two ¾-inch to 1-inch screws into soft pine door casing — not into the structural door stud. A moderate kick delivers enough force to split the wood casing and pop the door open regardless of the lock quality. Studies show most kick-in attacks take under 2 seconds.
Replace the standard strike plate with a heavy-gauge steel plate (at least 14 gauge). Use 3-inch screws that penetrate through the door casing and into the structural door stud behind it. This distributes kick force across the stud, requiring much greater force to defeat.
For maximum protection, door reinforcement kits wrap armor around the door jamb, hinge side, and door edge. Products like Door Armor Max cover all three failure points. These make kick-in attacks extremely difficult even against determined attackers.
A quality reinforced strike plate costs $15–$30. Professional installation by a locksmith costs $50–$100 for the full reinforcement. This is arguably the highest security ROI of any home improvement — preventing the most common forced-entry method for under $100.
