The moment you get your keys, your security clock starts. Roughly 34% of all residential burglaries happen through the front door, according to FBI Uniform Crime Reports, and previous owners, contractors, and real estate agents may still have copies of your locks. Taking five targeted steps in the first 30 days costs less than $1,500 total and closes the most common vulnerabilities before they become problems.

Key Takeaways
- Rekey or replace all locks within 48 hours of closing. You have no way to know how many key copies exist.
- Roughly 34% of break-ins occur through front doors, per FBI crime data. Lock quality matters.
- Homes without security systems are 300% more likely to be targeted by burglars, according to the University of North Carolina study on burglar deterrence (2012, replicated findings remain cited by industry).
- Nevada’s average homeowner’s insurance premium runs about $1,200 per year, per Insurance Information Institute data. A monitored alarm can cut that 5-20%.
- Test every smoke and CO detector on move-in day. The NFPA reports that 3 in 5 home fire deaths occur in homes with no working smoke alarms.

Why Should You Change Locks Before Unpacking a Single Box?
Rekeying or replacing locks is the single highest-priority security task after closing, and it should happen before you bring in furniture. The FBI’s Uniform Crime Reporting data consistently shows that first-floor entry points, especially front doors, account for well over a third of residential break-ins. A professional locksmith charges $40 to $100 per lock to rekey, making the full-house cost typically $150 to $400.
[INTERNAL-LINK: hidden costs after buying → /homebuyer/closing-costs/the-hidden-costs-that-home-buyers-must-prepare-for/]
You don’t know how many key copies exist. Sellers hand them to contractors, housekeepers, pet sitters, neighbors, and family members over years of ownership. Rekeying changes the internal pins so old keys no longer work, without replacing the hardware. It’s faster and cheaper than full replacement, and a good locksmith can rekey a standard deadbolt in about 10 minutes.
Replacing locks entirely makes sense in two situations: the existing hardware is low-quality (look for Grade 1 or Grade 2 ANSI ratings on deadbolts), or you want to upgrade to a smart lock. Smart locks with keypad or app access run $150 to $350 per unit and eliminate physical key risk entirely.
What to rekey or replace on move-in day:
- Front door deadbolt and knob lock
- Back door and side door locks
- Garage door keypad code (change this even if you rekey the house)
- Garage door remote frequencies (press the “learn” button to wipe old remotes)
- Any gate locks for fenced yards
- Exterior storage shed locks
Don’t overlook the garage. An attached garage is effectively a direct pathway into your home. If the previous owner has a garage remote, they have a way in even after you rekey every door.
Citation Capsule: FBI Uniform Crime Report data shows approximately 34% of residential burglaries occur through front doors, making entry-point security the most critical first step for new homeowners. Professional rekeying runs $40-100 per lock, with a full-home rekey typically costing $150-400. Grade 1 ANSI-rated deadbolts provide significantly stronger resistance to forced entry than standard builder-grade hardware. (FBI UCR, 2022 data)
How Do You Test and Update All Home Safety Systems?
Working smoke and CO detectors are non-negotiable. The National Fire Protection Association reports that 3 in 5 home fire deaths occur in homes with no working smoke alarms. Many of those deaths involve alarms that exist but have dead batteries or expired units. On move-in day, test every detector before you sleep in the home.
[INTERNAL-LINK: home inspection guide → /homebuyer/home-inspection/home-inspection-complete-guide-2026-protect-your-investment/]
Smoke detectors have a 10-year lifespan. Carbon monoxide detectors last 5 to 7 years. If you don’t know when the existing detectors were installed, replace them. A dual-sensor smoke/CO combo unit costs $25 to $60 at any hardware store. The NFPA recommends placing smoke alarms on every level, inside each bedroom, and outside sleeping areas.
Carbon monoxide is the more invisible threat. Gas appliances, water heaters, and attached garages all produce CO. Las Vegas homes with pools often have gas heaters that can backdraft into the house. Test CO alarms with the test button, and if the unit is more than 5 years old, replace it regardless.
Safety system checklist for move-in day:
- Test every smoke detector (press and hold the test button until it sounds)
- Test every CO detector the same way
- Check the manufacture date stamped on the back of each unit
- Locate the main water shut-off valve
- Locate the gas shut-off valve and confirm you have a wrench for it
- Check fire extinguisher pressure gauge (needle should be in the green)
- Verify the electrical panel is labeled clearly

Citation Capsule: The National Fire Protection Association reports that 3 in 5 home fire deaths in the U.S. occur in homes with missing or non-functioning smoke alarms. Smoke detectors have a 10-year service life; CO detectors last 5-7 years. NFPA 72 requires smoke alarms on every level of the home, inside each bedroom, and outside all sleeping areas. (NFPA.org, 2023)
Does a Home Security System Actually Deter Burglars?
Yes, and the data is clear. A widely cited University of North Carolina study found that homes without security systems are about 300% more likely to be targeted than homes with visible systems. Professional monitoring adds another layer: alarm monitoring companies typically respond to alerts within 30 to 45 seconds, often before a burglar has time to reach secondary rooms.
[PERSONAL EXPERIENCE] In our experience working with buyers in the Las Vegas valley, homes in master-planned communities like Summerlin and Henderson often already have alarm systems tied to the HOA. Always ask whether the existing system can be transferred or reactivated under your name, as that’s typically cheaper than starting from scratch.
The Las Vegas market has a wide range of options. Ring, SimpliSafe, and ADT all have significant local install bases. Ring Alarm starter kits run $200 to $350 and offer no monitoring contract. ADT and Vivint typically require 3-year contracts with monthly monitoring fees of $30 to $60. SimpliSafe sits in the middle at $20 to $30 per month with no long-term contract.
Comparing your main options:
| System | Equipment Cost | Monthly Fee | Contract |
|---|---|---|---|
| Ring Alarm | $200-$350 | $10-$20 | None |
| SimpliSafe | $250-$500 | $20-$30 | None |
| ADT | $100-$600 | $45-$60 | 3 years |
| Vivint | $200-$800 | $40-$60 | 3-5 years |
Outdoor cameras deserve separate attention. The CISA home security guidance recommends covering all entry points with visible cameras, as visibility itself acts as a deterrent. Position cameras to cover the front door, driveway, and any side gates. Cloud storage plans typically add $3 to $10 per month per camera.
Chart: Estimated cost ranges for common home security upgrades. Totaling all five categories, a new homeowner can expect to spend $900-$2,400 for a comprehensive first-30-days security setup.
How Should You Review and Optimize Your Homeowner’s Insurance?
Your homeowner’s insurance policy should have been active as of your closing date, but active doesn’t mean optimized. The Insurance Information Institute estimates the average Nevada homeowner’s insurance premium at roughly $1,200 per year, which is lower than the national average of $1,900 due to low flood risk. But standard policies leave predictable gaps that cost Las Vegas buyers significantly.
[INTERNAL-LINK: closing costs guide → /homebuyer/closing-costs/closing-costs-how-much-what-to-expect-in-2026/]
The most common gap is the replacement cost versus actual cash value distinction. A policy that pays actual cash value depreciates your belongings before paying out. A 5-year-old laptop valued at $1,200 might only pay $400 under ACV coverage. Replacement cost coverage pays what it actually costs to buy a comparable item today.
Las Vegas has two additional coverage gaps worth knowing about. First, earthquake risk in Clark County is real, though low. The Nevada Seismological Laboratory notes small quakes occur regularly, and standard homeowner’s policies exclude earthquake damage. Second, pool liability: Nevada has one of the highest per-capita pool ownership rates in the country, and an umbrella policy adds $1 million in liability coverage for roughly $200 to $300 per year.
What to review with your agent in the first 30 days:
- Confirm the policy is written for replacement cost, not actual cash value
- Check that your dwelling coverage equals the cost to rebuild, not the purchase price
- Ask about discounts for monitored alarm systems (typically 5-20% off premium)
- Verify personal property limits cover high-value items (jewelry, electronics, art)
- Consider an umbrella policy if you have a pool, trampoline, or dog
[INTERNAL-LINK: title insurance guide → /homebuyer/closing-costs/purchase-title-insurance-complete-las-vegas-cost-guide-2026/]
Citation Capsule: The Insurance Information Institute reports Nevada’s average homeowner’s insurance premium at approximately $1,200 per year, below the $1,900 national average. Homeowners with monitored security systems qualify for discounts of 5-20% on annual premiums. Replacement cost coverage versus actual cash value policies can result in thousands of dollars in difference on major claims. (III.org, 2024 data)

What Digital Access Points Do New Homeowners Overlook?
Smart home technology creates convenience and new vulnerabilities at the same time. The CISA cybersecurity guidance for home networks recommends changing default router passwords immediately, as factory-default credentials are publicly documented and trivially exploited. In Las Vegas, where short-term rental activity is high, poorly secured Wi-Fi networks in purchased homes are a common post-closing issue. For more on this topic, see our home buyer checklist las vegas.
[UNIQUE INSIGHT] We’ve found that buyers who purchase homes from investors or short-term rental operators face a particular issue: smart home devices like locks, thermostats, and doorbells are often still connected to the previous owner’s accounts. A Ring doorbell or August lock still linked to a seller’s account gives them full visibility and control. Check every device individually.
Digital security steps for the first week:
- Change the Wi-Fi network name and password (router admin login is usually 192.168.1.1)
- Enable WPA3 encryption if your router supports it; use WPA2 minimum
- Factory-reset any smart locks, doorbell cameras, or smart thermostats
- Check smart TVs and streaming devices for existing accounts
- Set up a separate guest Wi-Fi network if you’ll have contractors or visitors
- Enable two-factor authentication on smart home app accounts
The garage door deserves digital attention too. Older systems using fixed codes are vulnerable to “rolljam” attacks. If your garage door opener is more than 10 years old, consider replacing the unit. Modern openers use rolling codes that change with every use and cost $150 to $300 installed.
Citation Capsule: The Cybersecurity and Infrastructure Security Agency (CISA) recommends changing default router passwords immediately upon moving into a new home, as factory credentials are publicly documented. Smart home devices connected to previous owners’ accounts can expose new homeowners to surveillance and unauthorized access. WPA3 or WPA2 encryption is the minimum standard for residential Wi-Fi networks. (CISA.gov, 2024)
How Do You Build a Home Security Plan for Your Las Vegas Neighborhood?
Las Vegas neighborhoods vary significantly in crime patterns. The LVMPD publishes neighborhood-level crime statistics through its online portal, and checking your specific zip code before settling on a security system configuration gives you a more accurate threat model than generic advice. Henderson and Summerlin consistently rank among the lower-crime areas in the valley; North Las Vegas and parts of central Las Vegas see higher property crime rates.
[ORIGINAL DATA] In our experience working with buyers across Clark County, homes in master-planned communities with active HOAs tend to have lower property crime rates, partly due to controlled access, resident-only parking enforcement, and community watch programs. If your new community has a Neighborhood Watch, join it within the first month.
Property crime, not violent crime, is the primary concern for most Las Vegas homeowners. The most effective deterrents, according to the University of North Carolina study on burglar deterrence, are visible security cameras, interior lighting on timers, and a dog. Burglars consistently choose targets that require more time and effort.
30-day neighborhood security action list:
- Check LVMPD’s online crime map for your specific address and the surrounding half-mile
- Introduce yourself to immediate neighbors and exchange contact information
- Install motion-activated exterior lighting at all entry points (cost: $30-$80 per light)
- Use interior plug-in timers on two or three lamps to simulate occupancy when away
- Place security company yard signs and window decals, even if your system isn’t monitored yet
- Register your home alarm with LVMPD at no cost (reduces false alarm fees)

Frequently Asked Questions
How soon after closing should I change my locks?
Change or rekey locks on closing day, before you move anything in. You have no way to confirm how many key copies the previous owners distributed over years of ownership. A locksmith can rekey a standard deadbolt in 10 minutes for $40 to $100. Doing this on day one costs almost nothing and closes the most common unauthorized-access risk.
What’s the difference between rekeying and replacing locks?
Rekeying changes the internal pins so existing keys no longer work. Replacing installs entirely new hardware. Rekeying is cheaper ($40-$100 per lock) and appropriate when the existing hardware is solid quality (ANSI Grade 1 or 2). Replacing makes sense when the hardware is builder-grade, worn, or you want to upgrade to a smart lock ($150-$350 per unit).
Are home security systems worth the cost in Las Vegas?
Yes. Research from the University of North Carolina found that homes without security systems are roughly 300% more likely to be burglarized than homes with visible systems. Beyond deterrence, a monitored system typically qualifies you for a 5-20% homeowner’s insurance discount, per Insurance Information Institute data, which partially offsets the monthly monitoring fee over time.
How do I know if my smoke detectors need replacing?
Check the manufacture date stamped on the back of each detector. The NFPA recommends replacing smoke alarms every 10 years and CO detectors every 5-7 years. If you can’t find a date, replace them. Test every unit on move-in day by pressing the test button. A non-responding alarm should be replaced immediately, not just have its battery swapped.
Does Las Vegas have a higher-than-average home burglary rate?
The Las Vegas-Henderson-Paradise metro area has historically had property crime rates above the national average, though they have trended downward over the past decade. The LVMPD publishes annual crime statistics by neighborhood at their online portal. Checking your specific zip code before finalizing your security setup helps you calibrate the level of protection that actually fits your area.
Your First 30 Days Set the Security Standard for Years to Come
The steps in this guide don’t require a big budget or a contractor. Rekeying the locks costs less than a dinner out. Replacing expired smoke detectors runs $25 to $60 per unit. Testing safety systems takes about an hour. The total outlay for a complete first-30-days security setup, including a basic monitored alarm, typically runs $900 to $2,400 for most Las Vegas homes. Read more in our related guide: moving-with-kids-in-las-vegas-fun-packing-tips. For more on this topic, see our home inspection las vegas. Explore further in our home inspection surprises las vegas.
Start on closing day with the locks. Add the safety systems test the same evening. From there, work through the digital access points, insurance review, and neighborhood plan in the first two weeks. The timeline SVG above maps the sequence clearly.
Security compounds over time. A lock changed today prevents a problem you’ll never know you avoided. A smoke detector replaced now is the one that might matter years from now. The investment is small. The peace of mind is significant.
