Home Security Checklist for New Homeowners in 2026

Buying a house is exciting, but it also comes with a to-do list most new homeowners do not expect. Somewhere between unpacking boxes and figuring out which switch controls the garage light, home security tends to slip down the priority list. It shouldn't. The first few weeks in a new house are exactly when your home is most vulnerable, since you do not yet know who else might have a key, how the previous owners handled maintenance, or where the weak points are.

This checklist walks through the practical steps every new homeowner should take, roughly in the order you should tackle them, so your new place feels safe from day one.

Week One: Handle the Basics Before You Fully Unpack#

Rekey or replace every exterior lock#

You have no idea how many copies of the old keys exist. Real estate agents, contractors, dog walkers, neighbors, and previous tenants may all have had access at some point. The Federal Trade Commission and most local police departments recommend rekeying locks immediately after moving in, since it is inexpensive and closes off any access you cannot account for. A locksmith can usually rekey existing hardware in under an hour, or you can install new smart locks if you want keyless entry as part of your setup.

Walk the perimeter and check every entry point#

Spend an afternoon walking around the outside of the house with a notepad. Check that:

• Every window latches and locks properly
• Sliding glass doors have a secondary bar or pin lock
• The garage door opener works and the manual release is not accessible from outside
• Exterior doors have solid frames, not just decorative hardware
• Gates and fences close and latch securely

Older homes especially can have warped frames or worn-out latches that look fine but do not actually secure the opening.

Locate the utility shutoffs and breaker panel#

This is not strictly a security task, but it belongs on every new homeowner list. Know where your water shutoff, gas shutoff, and electrical panel are before you need them in an emergency. Label the breaker panel if the previous owner did not.

Week Two: Lighting, Visibility, and Landscaping#

Improve exterior lighting#

Poor lighting around entry points is one of the simplest things burglars look for. The National Crime Prevention Council has long recommended motion-activated lighting near doors, garages, and dark side yards as a low-cost deterrent. LED motion lights are cheap, easy to install, and immediately make a house look occupied and watched.

Trim back hiding spots#

Overgrown shrubs near windows and doors give intruders cover to work unseen. Trim anything that blocks a clear line of sight from the street or from your own windows. This also happens to make the yard look better, so it is a win either way.

Check house numbers are visible#

If emergency responders cannot find your address quickly at night, it slows everything down. Make sure numbers are large, reflective, and lit if possible.

Week Three: Build Your Security System#

This is where most new homeowners either overinvest in a pile of disconnected gadgets or underinvest and hope for the best. A better approach is to think in layers: monitoring at the door, coverage of key entry points, and a way to keep an eye on things when you are not home.

Start with a monitored alarm system#

A professionally monitored home security system is still the backbone of a solid setup. Door and window sensors alert you the moment something opens when it shouldn't, and monitored systems can dispatch help even if you are not able to call yourself. This matters more in a new home than almost anywhere else, since you are still learning the neighborhood's normal patterns and may not immediately recognize what looks off.

Add security cameras at key points#

Cameras do double duty: they deter would-be intruders and they give you visual confirmation of what is actually happening, which cuts down on false alarms and 2 a.m. guessing games. Prioritize:

• Front door and driveway
• Back door or any secondary entrance
• Garage
• Any ground-floor window that is not easily visible from the street

Modern security cameras with HD video and smart alerts can tell the difference between a person, a package, and a passing car, so you are not getting notified every time a squirrel runs across the yard.

Put a smart doorbell camera on your porch#

If you only add one camera in your first month, make it the front door. A doorbell camera lets you see and speak to whoever is there without opening the door, whether it is a delivery driver, a solicitor, or someone you would rather not answer for. It also creates a recorded history of who comes and goes, which is useful for package theft disputes and insurance claims alike.

Tie it together with smart home automation#

Once the basics are in place, home automation features let your security system do more with less effort on your part. Smart locks you can lock remotely if you forget on your way to work. Lights that turn on automatically at dusk. Thermostats that adjust when the system senses no one is home. None of this replaces good security habits, but it removes a lot of the small daily friction that causes people to skip steps.

Week Four: Test Everything and Build Habits#

Test the system end to end#

Do not assume everything works just because it is installed. Trigger a test alarm, confirm your monitoring center receives it, and make sure your phone gets push notifications. If you went with a professionally installed system, ask your installer to walk through a full test with you before they leave, and confirm who to call with questions afterward. Vivint's team can be reached at 866-417-1540 if you need help configuring or troubleshooting your setup.

Set up user codes and household access#

If you have a smart lock or alarm keypad, set individual codes for family members, and temporary codes for house cleaners, dog walkers, or contractors instead of handing out a physical key. Individual codes also let you see exactly who came and went and when, which a shared code cannot do.

Register with local resources#

Some police departments offer free home security assessments or vacation watch programs while you are away. The National Crime Prevention Council also has a searchable list of local safety resources by state. It is worth five minutes to see what is available where you live.

Create a household emergency plan#

Sit down with everyone in the household and agree on:

• What to do if the alarm goes off
• Where to meet outside in a fire
• Who is the designated emergency contact
• How to disarm the system for legitimate visitors

This sounds basic, but a surprising number of false alarms and confused 911 calls come from households that never actually discussed the plan out loud.

Ongoing: Keep the System Current#

Security is not a one-time project. Revisit your setup every six months:

• Replace batteries in sensors and cameras
• Update passwords, especially for any Wi-Fi connected devices
• Review who still has door codes or key fobs
• Check for firmware updates on cameras and locks
• Reassess coverage if you have added a shed, remodeled, or changed the landscaping

The Consumer Product Safety Commission also periodically issues safety notices related to smart home devices, so it is worth a quick search if you notice anything acting strangely.

Quick Reference Checklist#

• Rekey or replace all exterior locks
• Inspect every window and door for solid function
• Add motion-activated lighting at entry points
• Trim landscaping blocking sightlines
• Confirm house numbers are visible at night
• Install a monitored alarm system
• Add cameras at front, back, and garage
• Install a doorbell camera
• Connect smart locks and automation
• Test the full system end to end
• Set individual access codes
• Build a household emergency plan
• Schedule a six-month security review

Getting through this list will not take long, but it puts you well ahead of most new homeowners who put security on the back burner.

Common Questions#

How soon after moving in should I change the locks?

As soon as possible, ideally within the first day or two. Rekeying is fast and inexpensive compared to the risk of an old key still being in circulation.

Do I need both an alarm system and cameras, or is one enough?

They serve different purposes. An alarm alerts you and a monitoring center the moment a door or window opens. Cameras let you see what is actually happening and provide recorded evidence. Together they cover both detection and verification, which is why most complete home security setups include both.

What is the most overlooked item on a new homeowner security checklist?

Exterior lighting. It is inexpensive, quick to install, and one of the most effective deterrents according to crime prevention research, but it is easy to forget in the rush of moving-in tasks that feel more urgent.
