August Door Reinforcement Kit
Best OverallPros
- Designed specifically for August locks
- Includes 3-inch screws for deep frame bite
- Easy installation with included hardware
Cons
- Only fits August latch sizes
- Strike plate is painted, may chip
The August Door Reinforcement Kit is the official accessory from the manufacturer. It replaces the standard strike plate with a heavier-duty steel version and includes 3-inch screws that anchor into the door frame stud. Owner reviews on Amazon and Home Depot consistently report a noticeable improvement in door alignment and resistance to forced entry.
This kit is a direct replacement for the strike plate that comes with August Smart Lock Pro and August Wi-Fi Smart Lock. Installation takes about 10 minutes with a Phillips screwdriver. The included screws are longer than typical 1-inch screws, which helps prevent the door frame from splitting under a kick-in attempt.
Armor Concepts Defender
Best Budget Frame ReinforcementPros
- Reinforces the door frame, not just the strike plate
- No need to replace existing strike plate
- Works with any deadbolt
Cons
- Bulkier than a strike plate replacement
- May require drilling pilot holes
The Armor Concepts Defender is a steel bracket that installs on the door frame behind the strike plate. It uses 3-inch screws to anchor into the stud, and the bracket itself adds a layer of steel that resists splitting. This is a popular choice among August owners who want extra security without replacing the strike plate that came with their lock.
Owner reviews on Amazon note that the Defender is effective at preventing kick-in attacks. Installation requires a drill and a Phillips screwdriver, and the bracket fits most standard door frames. It is a budget-friendly option that does not interfere with the August lock's electronic operation.
Prime-Line E-2440
Best Heavy Duty SteelPros
- Extra-long 4-inch screws for deep anchor
- Heavy gauge steel construction
- Works with most standard deadbolts
Cons
- Strike plate may not match August finish
- Requires drilling for screw holes
The Prime-Line E-2440 is a heavy-duty steel strike plate that comes with 4-inch screws. It is designed to replace the standard strike plate on most residential doors. The longer screws provide a deeper bite into the door frame stud, which significantly increases resistance to kick-in attacks.
Owner reviews on Amazon highlight the solid feel of the steel plate and the ease of installation. The plate is available in a few finishes, but it may not perfectly match the brushed nickel or satin chrome of an August lock. It is a reliable option for those who want maximum screw length without buying a full reinforcement kit.
Kwikset 99030
Best Universal FitPros
- Fits most standard deadbolts and handlesets
- Includes both 2 1/2 and 3-inch screws
- Affordable price point
Cons
- Plate is thinner than some competitors
- Finish may not match August perfectly
The Kwikset 99030 is a universal replacement strike plate that works with most deadbolts, including August Smart Locks. It comes with two sets of screws (2 1/2-inch and 3-inch) so you can choose the depth that works best for your door frame. The plate is made of steel and has a satin nickel finish.
Owner reviews on Amazon say the plate is easy to install and improves the feel of the door latch engagement. Some users note that the plate is not as thick as the official August kit, but it is a good option if you need a universal fit for a non-standard door or if you are replacing a damaged strike plate.
Security Door Stopper
Best Rental FriendlyPros
- No drilling or permanent modification
- Portable and easy to remove
- Works with any door
Cons
- Less secure than a strike plate replacement
- Can be tripped over
The Security Door Stopper is a wedge-style door jammer that sits under the door handle. It does not require any drilling or permanent installation, making it ideal for renters who cannot modify the door frame. It is made of steel and uses a rubber pad to grip the floor.
Owner reviews on Amazon say it is effective at preventing the door from being pushed open, but it is not as robust as a strike plate reinforcement. It is a good temporary solution or a supplement to the August lock for extra security when you are home. It is not a replacement for a proper reinforcement kit.
What to check before buying a door reinforcement kit
Before you buy a reinforcement kit, measure the distance from the edge of your door to the center of the deadbolt hole. This is called the backset. Most August locks use a 2 3/8-inch or 2 3/4-inch backset. The kit you choose must match this measurement.
Also check the thickness of your door frame. Standard frames are 1 3/8 inches thick, but some exterior doors are thicker. The screws in the kit should be long enough to reach the stud behind the frame. A 3-inch screw is usually sufficient for standard construction.
Mistakes to avoid
Do not use screws that are too long for your frame. If the screw hits the stud too early or goes through the other side of the frame, it can split the wood. Always pre-drill pilot holes if the kit instructions recommend it.
Do not overtighten the screws on the strike plate. This can warp the plate and cause the latch to bind. Tighten until the plate is snug, then check that the deadbolt extends and retracts smoothly.
FAQs
Does the August Door Reinforcement Kit work with all August locks?
It is designed for August Smart Lock Pro and August Wi-Fi Smart Lock. It may not fit older August models or third-party locks.
Can I use a universal reinforcement kit with my August lock?
Yes, as long as the strike plate matches the backset and latch size of your August lock. Most universal kits work fine.
How long does it take to install a door reinforcement kit?
Installation typically takes 10 to 15 minutes with a Phillips screwdriver. Some kits may require a drill for pilot holes.
Will a reinforcement kit prevent kick-in attacks?
It significantly increases resistance by anchoring the strike plate into the door frame stud. No kit makes a door unbreakable, but it is a major improvement.
Do I need to remove my August lock to install the kit?
No, you only need to remove the existing strike plate on the door frame. The lock itself stays in place.
What size screws should I use for door reinforcement?
3-inch screws are the standard recommendation. They are long enough to reach the stud without being too long for most frames.
Can I install a reinforcement kit on a metal door frame?
Yes, but you may need self-tapping screws or a different type of anchor. Some kits are designed specifically for wood frames.
Is the Armor Concepts Defender better than a strike plate replacement?
It is different. The Defender reinforces the frame itself, while a strike plate replacement strengthens the latch engagement point.
Will a reinforcement kit void my August warranty?
No, because you are not modifying the lock itself. You are only replacing the strike plate, which is a standard door component.
Can I use a reinforcement kit on a rental property?
Yes, but check with your landlord first. Most kits require drilling new screw holes, which may be considered a modification.
What is the difference between a reinforcement kit and a door jammer?
A reinforcement kit replaces the strike plate to secure the latch. A door jammer is a wedge that sits under the handle to prevent the door from being pushed open.
Do I need to buy a separate kit for the August Smart Lock if I already have a reinforced door?
If your door already has 3-inch screws in the strike plate, you may not need a new kit. Check the existing screws first.
Our verdict
For most August Smart Lock owners, the official August Door Reinforcement Kit is the best overall choice for a perfect fit and easy installation. If you want to reinforce the door frame itself on a budget, the Armor Concepts Defender is a strong alternative that works with any lock.
