It sounds too simple to be true, but the most effective way to keep thieves out of your home is often the one homeowners forget. You have to lock your doors and windows. It feels like stating the obvious, maybe even insulting to your intelligence, but the data doesn’t care about your feelings.
According to the Federal Bureau of Investigation, 27.8 percent of burglaries in the United States in 2006 were no-force entries. That translates to more than 607,000 homes where intruders didn’t break a single pane of glass or kick down a door. They just turned the handle. They walked in.
“In more than 607,000 burglaries that year, the thieves simply opened an unlocked door or window and went right in.”
The stakes are high. Those 2.2 million burglaries in 2006 resulted in $4 billion in lost property. The average victim lost more than $1,800. While these stats include businesses, residential homes accounted for over 66 percent of the total crime. And here is the kicker: 63 percent of those residential break-ins happened during the day.
So, what does this tell you about the average burglar? They prefer the path of least resistance. They like to work when the house is empty. Since you can’t quit your job to sit in the dark with a shotgun waiting for a suspect, you need to make your home a hard target.

Thinking Like a Criminal
You’ve heard the saying: if a burglar is determined, they will get in. That’s technically true. But your goal isn’t to create an impenetrable fortress. Your goal is to make the job uncomfortable, dangerous, and time-consuming. Thieves want quick, easy wins.
Start by walking around your property. Inside and out. Look for weaknesses. How would you break in if you wanted to steal your own stuff?
The Deadbolt Difference
Your door is your first line of defense. It needs at least one deadbolt with a throw of one inch or longer. This means the bolt extends at least an inch into the door frame, engaging the wood so a kick won’t splinter it.
Ideally, you want a double cylinder deadbolt. This type requires a key to lock and unlock from both the inside and the outside. Why does this matter? If you have a door with a glass pane within 40 inches of the doorknob, a single-cylinder lock is a liability. A thief can smash the glass, reach in, and turn the thumb latch from the inside. With a double cylinder, they’d need a key.
However, there is a catch. In some municipalities, double cylinder locks violate fire codes. If a fire breaks out, you need to be able to exit quickly without fumbling for a key. If your town bans them, swap your glass-paned door for a solid wood or metal one.
Reinforcing the Frame
A solid metal door or a solid wood door with metal sheathing is optimal. Install a peephole so you can see who is knocking before you answer. But remember: the door is only as strong as the frame holding it.
Burglars often kick doors off their hinges. To prevent this, ensure your frame is secured with long screws. Specifically, use at least one three-inch screw for each hinge plate. Standard screws are too short; they pull out of the drywall or the stud. A three-inch screw bites deep into the structural framing, making it significantly harder to breach the entry point.
Sliding Doors and Windows
Sliding glass doors are notorious weak points. They are large, fragile, and often poorly secured. You don’t need a high-tech system to fix this. A simple piece of wood cut to fit inside the track can stop a sliding door from opening from the outside. It’s cheap. It’s invisible. It works.
For better security, install keyed locks on your sliding doors and windows. These engage the locking mechanism with a key, adding a layer of friction that a thief has to overcome.
Making your home a hard target doesn’t end with locks. A locked sliding door can still be shattered by a rock. But for now, focus on the basics. Secure the entry points. Make them hard to open. Make them hard to break.

The Three-Legged Stool of Home Security
Locking up is step one. It’s basic, sure, but with nearly 30% of burglaries in 2006 involving no-force entries, it’s also where most people fail. The other 70%? That’s the forced break-ins. The ones that leave you shaking.
The National Neighborhood Watch Association breaks this down into a triad: deter, detect, and delay. Miss one, and you’re leaving a gap.
Deterrence: Look Busy, Look Dangerous
Deterrence starts with hardware. Deadbolts. Solid frames. But it’s also psychological warfare. A yard sign works. It screams “I have an alarm.” Burglars are lazy. They want the path of least resistance. Give them a sign that says “hard target,” and they’ll move on.
You want your house to look lived-in. Even if you’re at work, leave a radio on. Set timers on lights. If it looks like people are home, the risk spikes. But be careful with your displays. Open curtains? Make sure they don’t frame a keyless entry car sitting in the driveway. If a thief can see the keys within reach, your car becomes the target, and breaking in might just be the fastest way to get those keys.
Dogs are tricky. A guard dog can be neutralized by a professional who knows to toss a steak or lure the beast into a bedroom and shut the door. Don’t rely on them for protection. Rely on them for detection. A bark is an alarm that doesn’t need batteries.
Detection: Make It a Smash-and-Grab
Detection changes the crime. Without an alarm, a burglary is a quiet theft. With one, it’s a smash and grab. The burglar is panicked. They’re scrambling for jewelry and laptops, not leisurely browsing.
Alarm systems vary in price, but the core requirements don’t change. You need sensors on every entry point. Motion detectors inside. And a loud outdoor siren. The noise is the point. It alerts the neighborhood. It draws eyes.
Here’s a technical warning: If you have a wireless alarm controlled by a key fob, watch out for signal cloning. Thieves with cheap radio tech can duplicate the “off” signal from the street. Hardwired systems or those with rolling codes are safer. Don’t advertise your specific system type on social media or yard signs. Just let them know you have one.
Lighting matters too. Motion-activated floodlights kill the cover of darkness. For daytime, treat your landscaping like a security system. Trim back shrubs. If a burglar can’t hide, they won’t linger. Consider planting thorny bushes under windows. It’s a physical barrier that says “no thanks.”
Delay: The Four-Minute Rule
Time is your best ally. The longer a burglar spends picking locks or breaking glass, the higher the chance they get caught or give up. The NNWA suggests that a four-minute delay is often enough to make the job not worth the risk.
How do you buy time? By removing easy options.
- Trim trees. Keep branches far enough from upper-story windows so they aren’t ladders.
- Secure basements. These are common entry points. Reinforce the glass.
- Lock the garage. It’s often the weakest link.
Every locked door, every reinforced window, adds seconds to the process. Add up those seconds, and you cross that four-minute threshold.
The Foundation: Locks
None of this matters if you leave the front door unlocked. It sounds obvious, but it’s the most common error. Deterrence, detection, and delay are layers. The lock is the base.
Secure your entry points. Trust your sensors. Keep an eye on the shadows. It’s not about building a fortress. It’s about making your home the least interesting house on the block.
“The longer it takes to get into your home, the more likely a burglar is to give up and move on.”
