Think your home is safe? You might be surprised. Many homeowners unknowingly make simple yet critical errors that compromise their home security.
These security mistakes burglars exploit are often easy to overlook—but they’re exactly what intruders look for when choosing a target.
In this guide, we’ll uncover the 12 most common security mistakes burglars exploit and show you how to fix them before it’s too late.
12 Common Security Mistakes That Attract Burglars
Here are the 12 most common home security oversights that burglars are counting on—and how to fix them before it’s too late.
1. Hiding Spare Keys in Obvious Locations

Hiding a spare key under a doormat, in a flowerpot, or tied through the letterbox might seem convenient, but these are the first places burglars check when attempting to break into a home.
In today’s world, this outdated habit significantly increases your risk of unauthorized access. Instead of leaving a key in plain sight, consider installing a weatherproof outdoor key safe with a secure combination lock.
Choose a discreet location for the key safe, away from direct visibility. Alternatively, entrust a spare key to a reliable friend, neighbor, or family member.

2. Not Installing a Smart Video Doorbell System

A video doorbell is one of the best home security tools available today. These devices allow homeowners to see, speak to, and monitor visitors in real time via their smartphones or tablets—even when they are not at home.
Smart doorbells typically come equipped with HD video recording, motion detection, and night vision capabilities.
They act as a powerful deterrent to criminals, who often avoid homes with visible surveillance equipment for fear of being recorded.
Additionally, video doorbells help manage package deliveries and identify unexpected guests, making them a multifunctional security solution that adds convenience and peace of mind.

3. Posting Photos of House Keys on Social Media
It might seem like a fun way to share life milestones, especially after moving into a new home, but posting close-up images of your keys online is a serious security risk.
High-resolution cameras can capture the exact pattern of your key cuts, and tech-savvy criminals can replicate them using 3D printing or basic cutting services. Even if your account is private, shared images can still be accessed or saved.
4. Ignoring Deadbolt Maintenance and Functionality

The deadbolt lock is a fundamental component of your home’s front door security. Positioned just below the handle, this heavy-duty locking mechanism should fully extend into the doorframe when engaged.
If it doesn’t, or if it’s loose, it may be possible for a burglar to use a credit card or similar object to bypass the lock. Regularly inspect your deadbolt for proper alignment and full functionality.

5. Broadcasting Your Vacation or Travel Plans on Social Media

Announcing travel plans or sharing vacation updates in real time on platforms like Instagram, Facebook, or TikTok can unintentionally signal to burglars that your home is vacant.
This information, even if shared privately, increases the risk of break-ins while you’re away. Statistics show that a significant number of burglaries are committed by someone the victim knows.
6. Failing to Secure Windows with Locks
While doors receive the most attention in home security, unsecured windows are a common point of entry for burglars. Many older homes still have windows without functioning locks, especially on upper floors.
Installing strong, tamper-resistant window locks is essential to prevent unauthorized access. Double-check that all windows are closed and locked before leaving your home, even those located on the second or third story.

7. Leaving Valuables Visible from Windows

High-value items such as laptops, designer handbags, gaming consoles, cameras, or jewelry should never be left in plain sight.
Burglars often scope out homes by walking or driving through neighborhoods, looking for signs of wealth or unattended valuables.
Ensure that electronics and expensive belongings are stored out of view, especially near windows or glass doors. Use blinds, curtains, or tinted window films to prevent prying eyes from peeking inside.
8. Not Using Motion-Activated Outdoor Lighting

Motion-sensor lighting is a highly effective way to enhance your home’s exterior security.
Unlike lights that stay on all night and consume energy, motion-activated lights only turn on when movement is detected, creating a surprise element that can startle and deter intruders.
These lights can be strategically installed near entrances, walkways, driveways, and backyard access points.

9. Having Low or No Perimeter Fencing Around Your Property

Fencing serves as a physical and psychological barrier between your home and potential intruders. A low fence—or no fence at all—offers little to no resistance to someone attempting to trespass.
Taller fences, especially those topped with trellises or thorny plants, are much more effective at discouraging break-ins.
Defensive landscaping, such as prickly shrubs or dense hedges, adds another layer of difficulty for anyone trying to approach your home unnoticed.
10. Overlooking Rear Yard and Garden CCTV Coverage

While many homeowners install security cameras at the front entrance, the rear yard and garden areas are often left unmonitored.
These locations can provide easy and unnoticed access for burglars. Installing weatherproof CCTV cameras at the back of your property helps protect valuable outdoor equipment, patio furniture, tools, and sheds.
Today’s wireless security systems are easy to install and often come with smartphone connectivity, motion alerts, and cloud storage.

11. Not Participating in a Local Neighborhood Watch Program

Joining a Neighborhood Watch group is a proactive way to enhance community safety and deter criminal activity.
These programs foster collaboration among residents, encourage the reporting of suspicious behavior, and promote a stronger sense of vigilance.
Homes in neighborhoods with active watch programs are statistically less likely to experience break-ins, as increased surveillance and communication make them less attractive targets.
12. Relying on Weak or Outdated Burglar Alarm Systems

A strong burglar alarm system remains one of the most effective deterrents against home intrusions. Homes without any type of security system are statistically more likely to be targeted by criminals.
However, not all alarms are equally effective. Outdated systems without app access or modern sensors can be easy to bypass.
Look for advanced systems that offer features like smartphone control, motion detection, real-time notifications, and automatic emergency service alerts.
