Home Security for New Homeowners: What to Do Before You Unpack
May 13, 2026

Quick Summary
Moving into a new home comes with security risks most buyers don't anticipate. This guide covers the essential steps to lock down your new home before you settle in.
Why New Homeowners Are More Vulnerable: Previous owners, contractors, and open house visitors may still have copies of your keys. Burglaries also peak during summer moving season, making a home in transition an easy target.
A Security Checklist for Your New Home: Treat the first week like a security audit; change locks, inspect every entry point, and check outdoor lighting. About 80% of break-ins happen at ground-level openings, so those are your highest priorities.
How to Set Up a Home Security System: A solid system covers all exterior entry points with 24/7 professional monitoring. Professional installation ensures optimal placement and fewer blind spots from day one.
Smart Home Security: Smart integration lets your security system work alongside locks, lights, and thermostats automatically. Auto-locking doors, motion-triggered lights, and away-mode settings are all manageable from a smartphone app.
Security Mistakes to Avoid as a New Homeowner: The most common missteps include not changing locks, leaving the garage interior door unlocked, and assuming a safe neighborhood means low risk. Posting move-in details publicly and ignoring second-floor access are also easy oversights.
You signed the papers, grabbed the keys, and now you are standing in a home that is officially yours. It is one of the biggest milestones in life. But before you start arranging furniture and debating paint colors, there is one thing that should come first: making sure your new home is secure.
Most first-time buyers focus on inspections, insurance, and mortgage rates during the buying process. Home security often falls to the bottom of the to-do list. That gap is exactly what this guide addresses. Below is a practical, room-by-room look at the security steps that matter most in those first few days and weeks after move-in.
Why New Homeowners Face Higher Security Risks
A new home feels safe because it is new to you—but the reality is different. Previous owners, contractors, and real estate agents may all have copies of your existing keys. Open house events could have given dozens of strangers a preview of your layout, entry points, and even where you plan to put valuables.
Moving season adds another layer of risk. Most residential moves in the United States happen between May and September. Data shows that burglaries peak during the summer months, particularly between June and August. Moving boxes stacked on a porch or in a garage signal that a home is in transition, and a home in transition is a home that is not yet locked down.
New Homeowner Security Checklist
Think of this as the security equivalent of a home inspection, and these are the items to address in the first week after closing.
Change Your Locks on Day One
This is the single most important step—you have no way of knowing how many copies of your keys exist. Former owners, their family members, housekeepers, dog walkers, and contractors could all have a set.
You have two options: rekeying your existing locks or replacing them entirely. Rekeying is the faster and more affordable route. A locksmith can rekey most homes for between $50 and $150, and the process makes every old key useless without swapping the hardware. If your locks are older, damaged, or you simply want better security, replacing them with new deadbolts or smart locks is worth the investment.
If you choose to replace your locks entirely, smart locks are a strong upgrade for new homeowners. They offer keyless entry through codes, smartphone apps, or even biometrics. You can issue temporary access codes to movers or guests and revoke them instantly. Many smart locks also integrate directly with home security systems, giving you a log of every time your door is opened or closed.
Audit Every Entry Point
Walk the full perimeter of your home. Check every exterior door, window, sliding glass door, garage entry, and basement access point. According to home security research, about 34% of burglars enter through the front door, 22% through the back door, and 23% through a first-floor window. That means close to 80% of break-ins happen at obvious, ground-level openings.
Look for doors without deadbolts, sliding doors without security bars or pins, windows with broken or missing locks, pet doors large enough for a person to crawl through, and garage doors that can be manually forced open. Document what you find and prioritize fixes before you finish unpacking.
Check Outdoor Lighting and Visibility
Well-lit exteriors are one of the simplest deterrents available. Burglars prefer to work in the dark and out of sight. Motion-activated lights near the front door, back door, garage, and side walkways force anyone approaching your home into visibility.
At the same time, look at your landscaping. Overgrown shrubs and trees near windows create hiding spots. Trim vegetation back so your doors and windows are visible from the street and to neighbors. A clear sightline is free security.
Inspect Any Existing Security Equipment
Some homes come with a security system already installed. If yours does, do not assume it is active or properly connected. Contact the previous owner or their security provider to understand what equipment is in place, whether the monitoring plan is transferable, and whether the system uses current technology.
Older systems may use outdated communication methods like landline connections, which are less reliable. Newer systems operate on cellular or Wi-Fi connections and often pair with smartphone apps for remote access. If the existing equipment is outdated or disconnected, replacing it with a modern, professionally monitored system is usually more cost-effective than trying to retrofit old hardware.
Setting Up a Home Security System in Your New Home
A security system is not a luxury item. It is one of the most practical investments a new homeowner can make. Beyond deterrence and monitoring, many homeowner insurance providers offer discounts for homes with professionally monitored security systems.
According to the Bureau of Justice Statistics, homes without a security system are significantly more likely to be burglarized. A University of North Carolina study found that roughly 60% of convicted burglars said the presence of an alarm system would cause them to choose a different target.
What a Modern Security System Should Include
At a minimum, a solid home security system covers these bases: door and window sensors on all exterior ground-level openings, at least one motion detector for interior coverage, a security camera at the front door (a video doorbell is ideal for this), and a central control panel or hub that connects everything. Additional layers such as outdoor cameras, glass break sensors, smart locks, and environmental detection for smoke, carbon monoxide, and water leaks round out a complete setup.
The most important feature to look for is 24/7 professional monitoring. Self-monitored systems rely on you seeing and responding to alerts via your phone. Professional monitoring means trained operators are watching for alarm signals around the clock and can contact emergency services on your behalf, even when you are asleep, traveling, or simply away from your phone.
Professional Installation vs. DIY
DIY systems have grown in popularity because of lower upfront costs and the appeal of self-installation. While they work well for renters and simple setups, for a new homeowner securing a long-term investment, professional installation has clear advantages. A trained technician assesses your home layout, identifies optimal sensor and camera placement, tests the system, and teaches homeowners how to use their system before leaving. That means fewer blind spots, fewer false alarms, and a system that works correctly from day one.
Smart Home Security: Going Beyond the Basics
A security system does its job best when it works with the rest of your home, not as a standalone silo. Smart home integration lets you create automations that improve both security and convenience.
For example, you can set your system to:
Lock all doors and arm the system at 11 pm every night.
Turn on exterior lights when the motion sensor detects movement after dark.
Send you a video clip when someone rings the doorbell while you are at work.
Adjust the thermostat to away mode when you leave your home.
These automations do not require technical expertise. Most modern security platforms let you set them up through a smartphone app in a few taps.
Security Priorities for Your First 30 Days
The first month in a new home is when you are most vulnerable. Routines are not established, you may not know your neighbors yet, and your home may still show visible signs of a recent move. Here is a practical timeline.
Week One
Walk the perimeter and secure every entry point. Change all locks or rekey them. Install or activate a security system with professional monitoring. Set up a video doorbell or front-door camera. Program exterior lights on timers or install motion-activated fixtures.
Week Two
Test all smoke detectors, carbon monoxide detectors, and any existing alarm sensors. Introduce yourself to neighbors—a simple introduction goes a long way, and neighbors who know you are more likely to notice and report suspicious activity around your home.
Weeks Three and Four
Break down and recycle all moving boxes (they advertise new, potentially expensive purchases). Set up smart home automations for lighting, locks, and thermostat. Review your homeowner insurance policy and confirm your security system discount. Store valuables in a fireproof safe, not in the master bedroom (75% of burglars go there first, according to a survey of convicted offenders reported by NBC New York).
Common Security Mistakes New Homeowners Make
Even security-conscious buyers overlook a few things, and these are the most common missteps.
Not changing the locks. This comes up in every security guide for a reason. It is easy to forget in the chaos of moving, but it is the single highest-risk item to skip.
Leaving the garage unsecured. About 9% of burglars enter through the garage. Many homeowners leave the interior door from the garage to the house unlocked, giving anyone who gets into the garage direct access to the home. A smart garage door opener can be set to close your garage any time that your system is armed.
Posting about the move on social media. Public posts about being away from home, moving schedules, or new expensive purchases tell potential intruders that a home is in transition, possibly unoccupied, or not yet secure.
Skipping the security system because the neighborhood feels safe. Burglary is a crime of opportunity, and it happens in every type of neighborhood. Visible security, even something as simple as a yard sign, makes a meaningful difference.
Ignoring second-floor access. Trees, trellises, or flat roofs near second-story windows create access points that many homeowners overlook.

Frequently Asked Questions
When should I set up a home security system after buying a house?
Ideally, within the first week of closing. The transition period between owners is when a home is most exposed. If possible, schedule installation before or during move-in day so you are protected from the start. Many security providers can work with your move-in timeline.
Is it really necessary to change locks on a new home?
Yes. There is no reliable way to account for every copy of the existing keys. Previous owners, contractors, real estate agents, neighbors, and previous house guests could all have copies. Rekeying typically costs between $50 and $150 and makes every old key useless. It is one of the fastest and most effective security upgrades you can make.
Do home security systems actually deter burglars?
Yes. Research consistently supports this. A University of North Carolina study found that about 60% of convicted burglars said the presence of a security system would cause them to seek a different target. Visible components like cameras, yard signs, and window stickers add to the deterrent effect.
What is 24/7 professional monitoring and do I need it?
Professional monitoring connects your security system to a trained response team that operates around the clock. When your system detects an alarm, the monitoring center verifies the event and contacts emergency services on your behalf. This is especially valuable when you are asleep, traveling, or unable to check your phone. For a new homeowner protecting a major financial investment, professional monitoring provides an important layer of coverage.
Can a security system lower my homeowners insurance?
Yes, in many cases. A number of insurance providers offer discounts for homes with professionally monitored security systems. The exact discount varies by provider and policy, but it is worth asking your insurer about when you set up or renew your coverage
What is the best security system for a first-time homeowner?
Look for a system that includes door and window sensors, a video doorbell or front-door camera, professional monitoring, and a mobile app for remote access. Smart home compatibility is also worth prioritizing so you can add devices over time.
How much does a home security system cost for a new home?
Costs vary based on the equipment you choose and whether you opt for professional monitoring. Systems with professional installation and monitoring typically range from roughly $30 to $55 per month. Some providers, like Brinks Home, include free professional installation with new system activation, which removes one of the most common upfront costs.
