Most people think home security starts and ends with locking the front door. While that’s important, it’s often not the first place someone with bad intentions looks.
Burglars usually look for the easiest way in. That could be a forgotten window, a side door that rarely gets used, or another part of the home that doesn’t get much attention. In many cases, the weak spots aren’t hidden at all. They’re everyday entry points that homeowners simply overlook.
Taking a closer look at these areas can help you spot problems before someone else does. Here are 10 vulnerable entry points around the home that are often targeted and what you should keep an eye on.

Windows
Ground-floor and basement windows are among the most common points of entry. They’re often left unlocked, fitted with weak latches, or hidden from street view by shrubs or fencing. Reinforcing window locks and adding security film or sensors can make forced entry much more difficult.
Front and Back Doors
Doors are the most direct access point into your home, and surprisingly, many rely on basic locks that are easy to kick in. A solid deadbolt, reinforced strike plate, and a solid-core or metal door can dramatically improve security. Don’t forget to check the hinges and door frame as well.
Garage Doors
Garages are a frequent target because they often provide direct access to the house. Older garage doors can sometimes be forced open, and side service doors are commonly overlooked. Make sure both the main garage door and any entry doors are properly locked and reinforced.
Sliding Glass Doors
Sliding doors can be lifted off their tracks or forced open if not secured. Adding a security bar or placing a metal rod in the track prevents the door from being opened from the outside. Reinforced glass film can also make the glass harder to shatter.
Pet Doors
Pet doors may seem harmless, but larger ones can be exploited. Burglars have been known to reach through to unlock nearby doors or even crawl through oversized openings. Electronic or collar-activated pet doors are a safer alternative.
Basement and Attic Windows
Basement and attic windows are often small, out of sight, and easy to overlook. Because they aren’t used daily, they may remain unlocked or poorly secured. Reinforcing locks and routinely checking them can eliminate an easy access point.
Chimneys and Vents
While less common, chimneys and large exterior vents can serve as entry points if not properly covered. Loose or damaged vent covers can be removed quietly. Secure screens and reinforced covers help prevent tampering.
Mail Slots
Mail slots located near door handles can allow someone to reach inside and unlock the door. Installing a secure internal shield or a lockable cover prevents access through the opening.
Skylights
Skylights are often overlooked when it comes to security. If they can be opened or accessed from a roofline, they may pose a risk. Ensure skylights are properly locked and consider reinforcing the glass if accessible.
Ground-Level Air Conditioning Units
Window and wall-mounted AC units can sometimes be pushed inward if not firmly secured. This creates a direct opening into the home. Installing brackets and ensuring the unit is tightly fitted reduces the risk.
