Why Door Reinforcement Kits Matter for Home Security
Forced entry through doors remains one of the most common ways burglars gain access to homes. A door reinforcement kit addresses the structural weaknesses that make standard doors vulnerable to kick-ins and prying. Door Armor specializes in this exact problem, offering patented galvanized steel solutions that homeowners can install themselves in under 30 minutes.
Most residential doors fail not at the lock, but at the frame, hinges, and strike plate. When force is applied, the frame splits before the lock fails. The best reinforcement kits address all vulnerable points: they reinforce the door jamb, protect the hinges, and secure the strike plate with long screws that anchor into the structural framing behind the drywall.
Whether a reinforcement kit is necessary depends on your actual risk. If you live in a higher-crime area, own a vacant vacation property, or experienced a previous break-in attempt, it's practical protection. For renters and those in low-crime areas, it's still valuable insurance against the most common entry method used by burglars.
Top Door Reinforcement Kit Options

Door Armor Single Door Security Set
The Door Armor Single Door Security Set is the starting point for homeowners protecting a single exterior door. At $79.00, this kit includes hinge shields and strike plate reinforcement designed for standard doors up to 1-3/4" thick.
The kit focuses on the highest-risk points: hinge shields prevent the door from being pried open at the hinges, while strike plate reinforcement uses long screws that penetrate deep into the door frame's structural wood. Installation takes about 30 minutes with basic tools: a drill, screwdriver, and measuring tape. The galvanized steel finish blends with existing hardware, so the installation doesn't advertise your security upgrades. The 30 minutes install process comes backed by the $500 Lifetime Guarantee against kick-in failure.
Best For: Homeowners protecting a single entry door who want affordable, straightforward security without unnecessary features.
This kit is designed for standard single doors. If your main entry has side lights or you need to protect multiple doors, you'll need a different solution.
Door Armor Side Light Door Security Kit
Doors with side lights present a unique problem: there's no solid jamb on the side where the glass panel is. The Door Armor Side Light Door Security Kit ($129.00) uses a sidelight jamb shield that screws into the face of the existing jamb to create the rigidity that would otherwise be missing.
The sidelight hinge shields attach the light frame to the main door frame at top and bottom, creating structural continuity that stops the side-light frame from being pried away. Burglars specifically target side-light doors because they're perceived as weak points.
Pro Tip: Measure your door opening carefully before ordering. Confirm your door thickness and side-light dimensions match the kit specifications.
If you have side lights, this is the only Door Armor option that addresses the specific structural problem they create.
Door Armor Double Door Security Kit
Double doors present a challenge: there's no center jamb, which means standard strike plate reinforcement won't work. The Door Armor Double Door Security Kit ($149.00) protects the top, bottom, hinges, and lock area of both door panels and includes a Night Lock door barricade for additional security when you're home.
Without a center jamb, doors can flex and separate, compromising the lock. This kit uses reinforcement at multiple points to create structural integrity across both panels. The Night Lock provides a manual barricade that prevents the doors from being forced open, creating multi-layer defense.
Installation is more complex than the single-door kit because you're coordinating hardware across two panels and installing the barricade mechanism.
How to Prevent Door Kick-Ins: Key Components
Door kick-in resistance depends on understanding which parts of the door assembly actually fail under force. The door itself is rarely the weak point; what fails is the connection between the door and frame, and the frame's connection to the structural wall.
The strike plate is where most standard doors fail. A typical strike plate is held by two short screws that only penetrate the jamb, not the structural framing. Long screws that anchor into the framing behind the drywall transform this weak point into a structural connection.
Hinge shields prevent the door from being pried open at the hinges, a common attack point. The door jamb itself needs reinforcement through a reinforcement plate that distributes force across a wider area, preventing localized failure.
| Component | Function | Installation Difficulty |
|---|---|---|
| Strike plate reinforcement | Anchors lock to structural framing | Low |
| Hinge shields | Prevents prying at hinges | Low |
| Jamb reinforcement plate | Distributes force across wider area | Medium |
| Long anchor screws | Penetrate framing, not just jamb | Low |
| Door frame bracing | Prevents frame separation | Medium |
The combination of these components creates a security barrier. Strength comes from coordinated reinforcement at every vulnerable point.
Door Security Hardware Installation: DIY Setup
Most door reinforcement kits can be installed by homeowners with basic tools and no prior experience.
Start by measuring your door: thickness, distance from door edge to frame, and hinge and strike plate height. Remove the existing strike plate and inspect the holes. Install the new strike plate with long screws, ensuring they penetrate at least 1.5 inches into the structural framing, this is the critical step.

Install hinge shields by removing the hinge pin, sliding the shield over the hinge barrel, and reinstalling the pin. For jamb reinforcement, mark the location of the reinforcement plate, pre-drill holes to prevent splitting, and install with provided hardware.
The entire process typically takes 30 minutes for a single door. Most homeowners find it faster than expected because the hardware is designed for straightforward installation.
Watch Out: Over-tightening screws can strip the wood or damage the hardware finish. Tighten until snug, then stop.
Door Jamb Reinforcement Cost and Value
A door jamb reinforcement kit ranges from $79 to $149 depending on the door type. This cost is justified by comparing it to alternatives: replacing a damaged door after a break-in costs $300-$1,000, and the intangible cost of a security breach is much higher.
The value proposition is simple. A reinforcement kit provides permanent, passive protection that requires no power, no monitoring, and no monthly fees. It works 24/7 whether you're home or away. This is fundamentally different from alarm systems, which detect intrusion but don't prevent it.
More importantly, a reinforced door provides critical time to call for help or prepare a response. The $500 Lifetime Guarantee removes the risk from the purchase decision.
How to Choose the Right Kit for Your Door
Your door type determines which kit you need. Standard single doors need the Single Door Security Set. Doors with side lights require the Side Light kit. Double doors need the Double Door kit.
Door thickness matters. Most residential doors are 1-3/4" thick, which is what standard kits accommodate. Confirm the kit specifications before ordering if your door is thicker.
The number of doors you need to protect affects your total investment. Some homeowners prioritize their front door first and add back door and sliding door protection later.
Material compatibility is worth considering. The galvanized steel finish is designed to blend with common hardware finishes like satin nickel, bronze, and stainless steel. If you're not comfortable with basic installation, hiring a handyman costs $50-$150, which is still far less than professional door installation.

Frequently Asked Questions
What makes a door reinforcement kit effective against forced entry?
An effective door reinforcement kit addresses the weak points where forced entry typically occurs: the door jamb, strike plate, hinges, and lock area. The best kits use heavy-duty steel components that prevent the door frame from splitting and the lock from being kicked through. Galvanized steel resists corrosion and maintains structural integrity over time. Police-tested kits have been proven to stop real-world kick-in attempts by reinforcing the door frame and distributing impact force across a larger area, buying critical time to call for help.
How long does door security hardware installation actually take?
Most door reinforcement kits, including Door Armor's system, install in under 30 minutes with basic tools like a drill and screwdriver. The process involves attaching hinge shields, reinforcement plates, and strike plate guards using provided screws. No special skills are required. The short installation time makes these kits accessible for DIY homeowners who want to upgrade their security without hiring a professional. Rental properties benefit from this speed, since tenants can install protection quickly without disrupting occupancy.
Is door jamb reinforcement cost-effective compared to other security upgrades?
Door jamb reinforcement kits start at $79 for single doors, making them one of the most affordable home security upgrades available. A full reinforcement system for multiple doors typically costs $150-$300, far less than replacing doors ($800-$2,000 each) or installing a security system ($1,000+). The lifetime guarantee against kick-ins means you're protected indefinitely without ongoing costs. When compared to the expense of repairing a forced-entry break-in or replacing stolen property, reinforcement kits deliver exceptional value.
Can door reinforcement kits work on rental properties?
Yes, many kits are renter-friendly because they attach using screws into the door frame rather than permanent modifications. The hardware remains discreet and matches standard finishes, so it doesn't make a rental look like a fortress. However, check your lease before installation. Some kits, like Door Armor, can be removed and taken when you move, though this requires careful uninstallation. For vacation rentals or properties you own, permanent installation provides maximum security and peace of mind.
Do door reinforcement kits work on all door types?
Most standard exterior doors benefit from reinforcement kits, but special door types require specific solutions. Single solid doors, double doors, and doors with side lights each have different weak points. Door Armor offers specialized kits for each type: the Single Door Security Set for standard doors, the Side Light Door Security Kit for doors with windows, and the Double Door Security Kit for French or patio doors. Sliding glass doors and specialty materials may need alternative approaches, so match your door type to the correct kit.
