Moving into a new home usually means dealing with boxes, utilities, furniture, repairs, and paperwork. Security often gets pushed down the list, even though the first few days after moving are one of the best times to review how the property is protected.
You may not know who previously had keys, which access codes are still active, whether windows lock properly, or whether connected devices are still linked to someone else’s account.
Before you fully settle in, check these important areas.
1. Change or Rekey Exterior Door Locks
One of the first things to address is access to exterior doors.
Previous owners, tenants, contractors, cleaners, real estate agents, or family members may have had copies of the keys at some point. Even if every key appears to have been returned, you cannot know how many duplicates were made.
Consider either replacing the locks or having suitable locks rekeyed.
Check all exterior entrances, including:
- Front doors
- Back doors
- Garage entry doors
- Side entrances
- Basement doors
If the property uses a smart lock, reset the device and remove old access codes or user permissions.
2. Test Every Window Lock
Windows are easy to overlook during a move.
Walk through the house and physically test each accessible window instead of simply checking whether it appears closed.
Look for:
- Broken locks
- Loose frames
- Windows that do not close completely
- Damaged latches
- Ground-floor windows hidden by landscaping
Pay extra attention to basement windows, windows beside porches, and any opening that can be easily reached from outside.
3. Reset Garage Access
If the house has a garage, do not assume that receiving the available remotes means nobody else can operate the door.
Reset the garage-door opener according to the manufacturer’s instructions and reprogram the remotes you plan to use.
If there is a keypad outside, create a new access code.
Also inspect the door connecting the garage to the house. It should close properly and have a functioning lock.
4. Check Existing Alarm and Security Systems
Some homes already have alarm panels, motion sensors, door sensors, cameras, or video doorbells installed.
Do not immediately assume these devices are active or configured correctly.
Find out:
- Which company supplied the equipment
- Whether a monitoring subscription is active
- Who controls the administrator account
- Whether sensors are still working
- Whether old users still have access
- Whether equipment requires new batteries
Reset passwords, PINs, and administrator credentials where possible.
Inherited equipment can be useful, but only after you know who controls it.
5. Review Smart Home Devices
Security concerns are no longer limited to physical keys.
A previous resident may have installed smart locks, cameras, thermostats, lighting, doorbells, speakers, hubs, or garage controls.
Factory-reset connected devices before linking them to your own accounts.
You should also change the Wi-Fi network name and password rather than continuing to use credentials left by the previous owner.
These details are easy to overlook and are examples of common home security problems that homeowners should address early. House Made Clear also covers everyday security mistakes that can leave otherwise well-protected homes more vulnerable than expected.
6. Inspect the Door Frames and Hardware
Changing a lock does not solve everything if the door itself is weak.
Check whether exterior doors fit properly within their frames and whether the deadbolt extends fully into the strike plate.
Look for:
- Loose strike plates
- Damaged wood
- Cracks around locks
- Loose hinges
- Misaligned doors
- Worn hardware
A relatively small repair may significantly improve the strength of an existing entrance.
7. Check Exterior Lighting
Walk around the property after dark.
You may notice areas that looked perfectly visible during the daytime but become poorly lit at night.
Check lighting around:
- Front entrances
- Driveways
- Garages
- Side paths
- Back doors
Replace failed bulbs and test motion-activated fixtures.
If you plan to use security cameras, make sure exterior lights do not create excessive glare directly in front of the lenses.
8. Look for Hidden or Forgotten Entry Points
A new homeowner may naturally focus on the front door while forgetting less obvious access points.
Walk around the entire exterior of the property and identify every possible entrance.
Depending on the home, this might include:
- Patio or sliding doors
- Basement entrances
- Side gates
- Balcony doors
- Utility-room doors
- Attached garage access
- Low or easily reached windows
You cannot properly secure a property until you understand all of its entry points.
9. Review Who Has Access to the Property
Moving often involves many people coming and going.
Contractors, movers, cleaners, decorators, relatives, and delivery personnel may all need temporary access.
Keep track of physical keys, garage remotes, alarm codes, and smart-lock permissions.
Once temporary access is no longer needed, remove it.
Smart locks can make this easier because individual codes can often be deleted without changing access for the entire household.
10. Create a Simple Security Routine
Once the immediate checks are complete, establish a regular routine.
Before leaving home or going to bed, quickly verify:
Doors → Windows → Garage → Alarm → Cameras
Periodically test batteries, camera feeds, sensors, lighting, and connected devices.
Security problems often develop gradually. A loose lock, dead battery, disconnected camera, or forgotten access code can remain unnoticed for months unless someone checks.
Final Thoughts
Moving into a new home is the ideal time to reset security rather than inheriting the previous owner’s habits and settings.
Start with locks and keys, then review windows, garage access, alarms, smart devices, lighting, and secondary entrances. Remove old permissions and make sure you understand who can currently access the property.
