10 Home Security Tips Every Baltimore Homeowner Should Know

Baltimore is a vibrant city, but like any major urban area, home security matters. The good news is that most residential break-ins are opportunistic — burglars look for the easiest target. Making your home even slightly harder to breach is often enough to send them elsewhere.

As licensed locksmiths serving Baltimore for years, we've seen the security mistakes homeowners make again and again. Here are the ten most impactful things you can do to protect your home.

1. Install ANSI Grade 1 Deadbolts

Most door locks that come pre-installed on homes are Grade 3 — the lowest quality. Upgrading to ANSI Grade 1 deadbolts on all exterior doors is the single most impactful security upgrade you can make. Look for deadbolts with a 1-inch minimum throw bolt.

2. Reinforce Door Frames

A strong lock is only as good as the door frame it's mounted in. Most break-ins happen by kicking in the door — not picking the lock. Install a strike plate with 3-inch screws that reach the wall studs, or a full door reinforcement kit for maximum kick resistance.

3. Rekey When You Move In

You never know how many copies of your keys exist. Previous owners may have given copies to neighbors, cleaners, contractors, and family members. Rekeying all exterior locks when you move in is cheap ($30–$80 per lock) and gives you a completely fresh start.

4. Secure Sliding Doors

Sliding glass doors are one of the most overlooked security vulnerabilities. Install a security bar in the track to prevent the door from being lifted off its rails or forced open. A secondary lock or pin lock adds another layer of protection.

5. Install Motion-Activated Lighting

Burglars hate lights. Motion-activated lights on all entry points — front door, back door, garage, and side gates — eliminate the darkness that criminals rely on. Solar-powered options make installation easy and cost-effective.

6. Use a Smart Lock on Your Front Door

Smart locks let you monitor who enters and exits your home, set access schedules, and revoke access instantly. You'll never have to worry about lost keys again, and many integrate with Ring, Nest, and other smart home systems.

7. Don't Advertise Your Absence

Avoid posting vacation photos on social media until after you return. Pile-up of mail, newspapers, and packages signals an empty home. Ask a neighbor to collect mail and park in your driveway occasionally when you're away.

8. Secure Your Garage

Garages are frequently targeted because of weak security. Add a deadbolt to the door connecting the garage to the house, lock the garage door release cord so it can't be triggered through the window gap, and consider a garage door lock bar.

9. Get to Know Your Neighbors

Neighbors who know each other notice strangers and unusual activity. Join your neighborhood watch or local Nextdoor group. This social layer of security is completely free and remarkably effective.

10. Schedule an Annual Security Assessment

Locks wear out, new vulnerabilities emerge, and family circumstances change. Having a licensed locksmith assess your home security annually ensures nothing is overlooked. We offer free security consultations for Baltimore homeowners.
