The Ultimate Home Security Checklist for 2024

Home security is rarely about one single upgrade. It’s about stacking simple improvements that make your home harder to target and easier to protect. Use this checklist to identify weak points, prioritize the biggest wins, and create a security plan that fits your routine.

1. Exterior doors and deadbolts

Most break-ins happen through common entry points. Start with every exterior door, including garage-to-home doors.

• Install a quality deadbolt on every exterior door
• Confirm the deadbolt fully extends and the door aligns correctly
• Reinforce the strike plate with longer screws anchored into studs
• Fix loose hinges, warped doors, or worn latches

2. Rekey after changes in access

If you don’t know who has a key, you don’t fully control access. Rekeying is one of the fastest ways to reset security without replacing all hardware.

• Rekey after moving into a new home
• Rekey after a roommate/tenant move-out
• Rekey after lost or stolen keys

3. Windows, sliders, and secondary entry points

Don’t overlook windows, basement doors, and sliding glass doors. These are common weak links when locks or latches are worn.

• Verify every window lock actually engages
• Add a secondary lock or security bar to sliding doors
• Keep basement entrances secured and well-lit

4. Lighting and visibility

Good lighting removes hiding spots and makes suspicious activity easier to notice.

• Add motion lighting near entrances and dark corners
• Trim shrubs that block sight lines to doors and windows
• Use timers or smart bulbs when traveling

5. Key control and daily habits

Security isn’t just hardware. It’s also how keys are managed and how consistently doors are locked.

• Know how many keys exist and who has them
• Avoid hiding spare keys outside in predictable locations
• Lock doors consistently, even for short errands

6. Consider upgrades that match your lifestyle

If you frequently have guests, kids returning from school, or service visits, a keypad or smart lock can reduce the need for spare keys and simplify access. The best upgrade is the one you’ll use correctly every day.
