Home security has come a long way, but many homeowners still rely on outdated habits that can leave their property vulnerable. From fake rock key hides to ignoring cyber-savvy burglars, these old habits are relics in a world where security threats have evolved. Updating your approach is essential—not just for peace of mind, but for real protection. Here are 12 outdated security habits that may be doing more harm than good.
1. Hiding a Spare Key Under the Doormat
It may seem convenient, but hiding a spare key under the doormat is like leaving an open invitation to burglars. It’s one of the first places they check, and it renders your locks useless. Choose a smart lock, leave a spare with a trusted neighbor, or install a coded lockbox—anything but the classic under-the-mat trick. Today’s criminals are savvy—and your security should be, too.
2. Leaving Porch Lights on 24/7
A constantly lit porch may seem like a deterrent, but savvy intruders see it as a sign of absence. Lights that never go off suggest no one’s home to turn them off. Motion-activated or timer-based lighting does a better job of creating uncertainty and conserving energy. Make your lighting strategy smart and dynamic—not a glowing red flag.
3. Posting Vacation Plans on Social Media
Sharing your vacation in real time might earn hearts and comments, but it also signals to burglars that your house is wide open. Even with privacy settings, posts can be shared or seen by the wrong people. Wait until you return to share vacation highlights. Real-time bragging can turn into real-world break-ins if you’re not careful.
4. Using the Same Lock for Decades
That old lock might still turn, but it’s probably no match for modern lock-picking tools. Many older locks are easily bypassed or have worn-down components that compromise security. If your locks haven’t been updated since you moved in—or ever—it’s time for an upgrade. Consider high-security deadbolts or smart locks with tamper alerts.
5. Ignoring Smart Home Security Options
From doorbell cameras to app-controlled alarms, today’s smart systems offer real-time peace of mind. Yet many homeowners skip these options out of habit or intimidation. The truth is, they’re easier to install than ever and can alert you instantly to suspicious activity. Ignoring these tools leaves your home stuck in the past—and more vulnerable.
6. Keeping Windows Unlocked or Cracked
A cracked window may let in a breeze, but it also opens the door—literally—for intruders. Unlocked or partially open windows are one of the easiest ways for burglars to gain access, especially on lower levels. Even upper-floor windows aren’t safe if there’s nearby fencing or patio furniture to climb. Always secure windows with reliable locks or limiters, even when you’re home.
7. Leaving Garage Doors Open or Unsecured
An open or weakly secured garage is a gift to thieves. It often houses tools, bikes, and even a door into your main living space. Many homeowners leave it wide open for convenience, forgetting that it’s an easy target. Modern garage door systems can be automated and monitored remotely—so there’s no excuse for leaving it vulnerable.
8. Forgetting to Update Alarm System Codes
Is your alarm system still set to the factory code? You might as well hang out a welcome sign for intruders. You’re not alone—and that’s a problem. Codes should be updated regularly and changed after housekeepers, contractors, or roommates move on. Outdated or shared codes make it easier for past visitors or potential hackers to disarm your system without a trace.
9. Not Using Deadbolts on Exterior Doors
That basic knob lock won’t stand a chance against a good kick. Exterior doors without deadbolts are an open invitation to forced entry. A high-quality deadbolt adds an essential layer of protection that makes your home much harder to breach. For even better security, go for a bump-proof or smart deadbolt that tracks use and alerts you.
10. Relying on “Beware of Dog” Signs Alone
While a “Beware of Dog” sign might give intruders pause, it’s no substitute for actual security measures. Experienced burglars know many of these signs are bluffs—and even a loud dog can’t call the police. Don’t let false confidence in a warning sign stop you from installing cameras, locks, or a full security system.
11. Skipping Security System Maintenance
A security system’s strength depends on regular care and updates to keep threats at bay. Failing to test sensors, replace dead batteries, or update software can leave your home unprotected without you even knowing. Dusty cameras, outdated firmware, or offline alarms create blind spots that criminals can exploit. Make it a habit to inspect your system regularly—set reminders, schedule checkups, and stay ahead of any tech hiccups.
12. Assuming Daytime Is Always Safe
Many homeowners let their guard down during daylight hours, believing break-ins only happen at night. In reality, most burglaries occur between 10 a.m. and 3 p.m., when homes are likely to be empty. Leaving doors unlocked or windows open “just for a bit” invites trouble. Daytime isn’t a safety shield—it’s when opportunistic thieves are most active and least expected.
