How to Secure Your Front Door, Starting With a Screwdriver
By Larry Betz | Prepared Not Paranoid https://www.preparednotparanoid.com/
When a door gets kicked in, it's often not the lock that gives out. It's the frame. The deadbolt stays locked, and the wood around it splits. That's good news, because learning how to secure your front door starts with one of the cheapest fixes in home security: a few long screws.
The Middle Ring
In Part 1, we split your home into four rings. This post is the middle ring: your doors, windows, and garage, where most break-ins actually happen. This ring's job is Delay. You want your doors to cost someone time, make noise, and keep them exposed long enough to be seen, heard, or caught.
Start With the Door
Not all doors give you the same protection.
Here's how the common types compare.
The one rule: never use a hollow-core door on the outside of your house, and that includes the door from the garage into the house. Hollow-core doors are built for closets and bedrooms, and they have very little resistance to force.
Locks and Lock Grades
A door is only as secure as its lock.
Here's how they compare.
The spring latch in your doorknob gives you very little security on its own, so every exterior door needs a deadbolt. A single-cylinder deadbolt (key outside, thumb-turn inside) is the right choice for most homes.
A double-cylinder deadbolt (a key on both sides) can help when there's glass near the lock, but it's a real safety risk: in a fire, everyone has to find a key before they can get out. Many local building and fire codes restrict them. Check your local codes first, and if you use one, keep a key close by but out of reach of the glass, and make sure every adult knows where it is.
Lock grades run from Grade 3 (the minimum, often what builders install) to Grade 1 (the highest). For your main entry doors, I'd go with Grade 2 or Grade 1. Look for the grade on the package.
The Frame and the Strike Plate: The Part That Often Fails
The strike plate is the metal plate on the door frame where the deadbolt goes in. In a lot of builder-grade homes, it's a thin plate held on with short screws that only go into the door trim. One good kick, and those screws pull out and the frame splits.
The fix: a heavy-duty strike plate held in with three-inch screws that reach the wall studs behind the frame. Do the same on the hinge side. It's one of the most cost-effective security upgrades you can make.
Upgrade Your Doors, Easiest First
You don't have to do it all at once.
Here's the order I'd do it in.
The Safest House on the Block walks through every step on that list, including how to check a frame for weak spots, when a security screen door or a reinforcement kit makes sense, how to handle glass near the lock, and what to look for in a smart lock.
Keys and Codes
Rekey or replace the locks when you move in. You have no idea how many keys the last owner handed out.
Never hide a spare key outside. Burglars know every hiding spot. Give a spare to a trusted neighbor instead.
What to Say
To a locksmith or installer:
"I want a Grade 1 or Grade 2 deadbolt on the front and back doors."
"Please use three-inch screws into the studs on the strike plate and the hinges."
To a contractor or sitter who needs access:
"I'll give you a temporary code that expires when the job's done."
To your family:
"Deadbolt every time, not just the knob."

SCAN Your Doors
S - See your environment. Check every exterior door, including the back, the side, and the door from the garage. Look at the frame, the strike plate, and any glass near the lock.
C - Create space. Each door is time between you and a threat. Make every one of them buy as much as it can.
A - Act deliberately. Start with the cheap fixes: long screws, a strike plate, a deadbolt on every exterior door.
N - Never doubt your gut feelings. If a door feels flimsy when you close it, it probably is.
Ask Yourself
How long are the screws in my strike plates right now?
Does every exterior door have a deadbolt, including the door from the garage?
Do I know everyone who has a key to my house?
Remember
Often, the door isn't the weak spot. The frame is. Put a quality deadbolt on every exterior door, use three-inch screws in the strike plates and hinges, and never hide a key outside. Some of the best upgrades in home security cost less than a dinner out.
