Door Reinforcement: The 4 Cheap Upgrades That Stop 90% of Kick-In Burglaries

The video clips of kick-in burglaries you’ve seen on social media have one detail in common: the door doesn’t break. The wood frame around the strike plate splinters. The 3/4-inch trim screws holding the strike plate pop out, and the door swings open with the strike plate still attached.

That detail matters because it tells you exactly what to fix, and the fix is cheap. Four upgrades, total cost under $150, can take an off-the-shelf builder-grade exterior door and turn it into something that resists a sustained kick. Most homeowners do all four in a single Saturday.

This is what they are, in order of impact-per-dollar.

Why Doors Fail (and Why It’s the Frame, Not the Door)

A standard exterior door is solid enough. The deadbolt is decent. What fails is the connection between the deadbolt and the wall — specifically, the strike plate, the screws holding it, and the door jamb wood that the screws bite into.

Builder-grade doors ship with three problems stacked on top of each other:

1. Short screws. Most factory strike plates use 3/4-inch screws. Those bite into the door jamb only — the half-inch-thick piece of pine the door is hinged into. They don’t reach the wall stud behind it.
2. A small strike plate. A 2.25-inch standard strike has minimal contact area with the jamb. Force concentrates on a small footprint.
3. A frame gap. The 1/4-inch reveal between the door and the jamb is exactly enough room for a flat pry bar.

When someone kicks the door, the lateral force shoves the deadbolt against the strike plate, the strike plate against the jamb wood, and the jamb wood against — almost nothing. The screws blow out of the jamb because they were never anchored to anything substantial.

The fixes below address each of these failures in turn.

Upgrade #1: Replace the Strike Plate with a High-Security One

Cost: ~$15 Time: 10 minutes Buy: Buy on Amazon

A high-security strike plate is a longer, thicker plate — typically 4 to 8 inches tall — that distributes force over a much larger area of the door jamb. The Defender Security and Prime-Line strike plates are the budget winners; both work fine. Sturdier all-metal options run $25–40.

Installation: unscrew the existing plate, swap it in, mark new screw holes if needed, and install. This is a screwdriver job. The hardest part is making sure the plate sits flush so the deadbolt still throws cleanly.

This single upgrade is the foundation. Everything else compounds on top of it.

Upgrade #2: 3-Inch Screws Into the Wall Stud

Cost: ~$5 for a pack of #10 × 3-inch wood screws Time: 5 minutes (already inside the strike plate replacement) Buy: Buy on Amazon

This is the most important $5 you will ever spend on home security.

When you install the new strike plate, replace the factory 3/4-inch screws with 3-inch wood screws. The 3-inch length passes through the jamb wood and bites deep into the wall stud (the 2×4 framing behind the jamb). The strike plate is now anchored to the actual structure of the house, not just the trim wood.

Field videos of strike plate failures and kick-test demonstrations have made this point repeatedly: factory screws blow out under impact, 3-inch screws don’t. The cost difference is approximately five dollars per door.

Do this on:

• The strike plate (where the deadbolt enters)
• The latch plate (where the doorknob latch enters — yes, this one too)
• The hinge plates on the inside edge of the door — the screws holding the hinges to the frame should also be 3-inch, biting into the stud. Hinges are the other failure mode in a kick attack, especially for outward-opening doors.

Most home improvement stores sell 3-inch #10 wood screws in small packs. One pack does a whole front door.

Upgrade #3: Install a Door Wrap or Frame Reinforcement Kit

Cost: ~$70 Time: 30–45 minutes Buy: Buy on Amazon

A door wrap is a steel sleeve that bolts around the door edge at the deadbolt and latch, plus a longer steel jamb shield that screws into the studs along the strike side of the frame. The most popular kit, Door Armor Max by Armor Concepts, is the standard recommendation in this category.

What it does:

• The door edge wrap prevents the deadbolt area from being split by repeated kicks (a failure mode where the deadbolt breaks through the door itself rather than the jamb).
• The jamb shield distributes kick force across a 4-foot length of stud rather than the 4-inch strike plate area. The jamb stops being the weak point.

Installation is a chisel-and-screwdriver job. Cut the existing door edge to fit the wrap, bolt the wrap on, then install the jamb shield with the included long screws. Most YouTube tutorials walk you through the install in 30–45 minutes; expect closer to an hour the first time.

This is the upgrade that takes a reinforced door from “tougher” to “not getting kicked in within a reasonable timeframe.”

Upgrade #4: Add a Secondary Lock

Cost: $20–80 depending on type Time: 10–20 minutes Buy: Buy on Amazon

A secondary lock is a second mechanical engagement point on the door — separate from the deadbolt — that has to be defeated independently. Three good options:

1. A door-mounted floor lock like a Door Devil or Nightlock (~$20–40). Installs at the base of the door, drops a steel bar into the floor when engaged. Useful primarily when you’re home; obvious when you’re not because it has to be set from inside.
2. A second deadbolt mounted higher or lower on the door than the primary (~$30–60 for the bolt, $20 for installation hardware). Doubles the work for a kick attack.
3. A jamb reinforcement plate on top of an existing strike plate (overlap install). Cheap, mostly redundant if you’ve already done #1 and #2 above, but worth considering for back doors where you skipped the wrap.

For most homeowners, the floor lock is the right pick — it’s the cheapest, the most visibly different from a normal door from the outside (which itself is a deterrent), and it’s easy to install.

What This Costs Together

A complete door reinforcement done right:

• High-security strike plate: $15
• 3-inch screws (one pack does the front door): $5
• Door Armor Max kit: ~$70
• Secondary lock (floor lock): $30
• Total: ~$120 per door

For a typical house — front door, back door, garage interior door — call it $300–400 total in materials and a Saturday of your time. That’s the strongest dollar-for-dollar improvement available in residential security.

What This Doesn’t Cover

Door reinforcement solves the kick-in attack, which is the dominant residential burglary entry method. It doesn’t address:

• Glass panels in the door. A door with decorative glass alongside the deadbolt is defeated by breaking the glass and reaching the lock. Replace decorative glass with security film (or a solid panel) before reinforcing the rest.
• The hinges on outward-opening doors. Outward-opening exterior doors (less common in U.S. residential, more common in apartments) are vulnerable to having the hinge pins driven out. Use security hinges with set screws.
• The window next to the door. A window within arm’s reach of the deadbolt can be broken to reach the lock. See the window security guide for the upgrade there.
• The garage interior door. Apply the same upgrades to the garage interior door — it’s an exterior door for security purposes, even though it doesn’t look like one. (More in the garage security walkthrough.)

Order of Operations for the Average Door

If you’re doing this for the first time, work in this order:

1. Remove the existing strike plate.
2. Drive the new strike plate position with a couple of 3-inch screws to make sure the deadbolt throws cleanly.
3. Install the Door Armor Max jamb shield (the long steel piece) over the strike side.
4. Install the door edge wrap.
5. Re-mount the strike plate over the jamb shield.
6. Replace the latch plate screws and hinge screws with 3-inch screws.
7. Install the floor lock if using one.
8. Test the door — open and close it several times, throw the deadbolt, make sure nothing binds.

The whole job runs about 90 minutes per door once you’ve done one. Front door first; back door second; garage interior third.

The combined effect is straightforward: the door now resists the energy of a sustained kick attack long enough that anyone trying loses interest and moves on. That’s the only outcome worth optimizing for, and these four upgrades produce it for less than the cost of a single security camera.
