Why Doors Fail During Kick-In Attacks
The average exterior door fails in one to three kicks. The lock usually survives. The strike plate—the metal piece screwed into the door frame that catches the deadbolt—rips out instead.
Most builders install strike plates with half-inch screws that bite only into the thin door jamb, not the structural framing behind it. One solid kick and the screws tear free, leaving your deadbolt dangling uselessly. The door swings open even though it was "locked."
This isn't a lock problem. It's a frame problem. You can have an ANSI Grade 1 deadbolt, but if the strike plate pulls out, the lock never had a chance. Fixing this weak point is the single most effective upgrade you can make to stop door kick-ins.
What a Reinforced Strike Plate Actually Does
A reinforced strike plate spreads impact force across a larger area and anchors deep into the door frame's stud. Standard plates are thin stamped metal, about three inches long. Reinforced versions are thicker gauge steel or brass, often six to twelve inches long, with multiple screw holes.
The critical upgrade: 3-inch screws. These reach past the jamb and bite directly into the wall stud—usually a 2x4 or 2x6—behind the trim. When someone kicks the door, the force transfers to solid lumber instead of splitting out a thin piece of pine trim.
High-security strike plates also feature a deeper bolt pocket to prevent the deadbolt from being pried or shimmed backward. Combined with a solid-core door and a Grade 1 or Grade 2 deadbolt, this setup can withstand hundreds of pounds of impact force.
DIY Installation vs. Professional Reinforcement
If you're handy, you can install a reinforced strike plate yourself. Remove the old plate, chisel the mortise deeper if needed, and drive 3-inch screws through the new plate into the stud. Use a drill with a pilot bit to avoid splitting the wood. Make sure at least two screws hit solid framing—not just the gap between studs.
Where DIY gets tricky: door frames aren't always plumb, screw holes don't always align with studs, and you may need to adjust the deadbolt alignment so it seats smoothly. If the bolt catches or binds, the lock becomes a hassle to use daily, and many people end up leaving it unlocked.
A locksmith checks alignment, installs the plate level, verifies the bolt engagement, and can add a matching hinge reinforcement or door wrap plate in one visit. For most homeowners, professional installation means the upgrade actually gets done right, and the door still operates smoothly.

Other Weak Points to Address
The strike plate is the biggest vulnerability, but not the only one. Hinge screws are another common failure point. Standard hinge screws are short; replacing them with 3-inch screws anchors the hinge side of the door to the stud. If both the strike and hinge sides are reinforced, the door becomes much harder to kick in from either direction.
Hollow-core doors offer almost no resistance. If you have one on an exterior entry, swap it for a solid-core wood or steel door. Pair that with a deadbolt that has at least a one-inch throw and an ANSI Grade 2 rating or better.
Glass sidelights and door glass are separate issues—tempered or laminated glass helps, but a determined intruder can still break through. Security film or an interior secondary lock (floor bolt or surface deadbolt) adds another layer. The goal is to make your home a harder target than the next one, so an intruder moves on.
What to Buy (or Ask Your Locksmith to Install)
Look for a strike plate labeled as "high-security" or "reinforced." It should be at least 6 inches long, 16- to 18-gauge steel or solid brass, and include four or more screw holes. Common brands include Defender Security, Prime-Line, and Door Armor—all widely available at hardware stores or online.
Make sure the package includes 3-inch screws. Some kits come with shorter fasteners; you'll need to buy deck screws separately if so. Stainless steel screws resist rust and won't snap under impact.
If you're calling a locksmith, ask about a strike plate upgrade during the same visit as a rekey or lock installation. Most mobile locksmiths carry reinforced plates in their truck stock and can install one in 15-20 minutes. It's a low-cost add-on that dramatically improves security. You can reach us anytime at (954) 888-8804 to schedule an appointment or ask about hardware options.
Does This Really Stop Kick-Ins?
Yes—when installed correctly. Law enforcement and insurance industry studies consistently show that reinforced strike plates and deep anchor screws prevent the majority of forced-entry attempts. Most burglars give up after a few kicks if the door doesn't budge. They don't carry battering rams; they rely on speed and the element of surprise.
No security measure is 100% foolproof, but a hardened door frame raises the effort and noise level enough that intruders move to an easier target. Pair the strike plate upgrade with good exterior lighting, a visible deadbolt, and trimmed landscaping near entries, and you've addressed the most common residential break-in methods.
If you've already been victimized or you're in a neighborhood with recent break-ins, this upgrade is the first thing to do. It costs less than a new lock and solves the actual failure point.
