20 Minute Home Security Audit: Room by Room Yes/No NFPA & CISA
Run a home security audit by checking eight areas: perimeter and visibility, exterior doors, windows and sliding doors, garage and outbuildings, lighting, alarms and detectors, cameras and digital devices, and household habits. Mark every item Yes, No, or N/A using a police-style checklist format, then turn each No into an action with an owner and a due date. Standards from NFPA and CISA back the fire, alarm, and network steps, and professional locksmith services can handle any lock fix the audit turns up.
TL;DR:
Hardware issues like misaligned locks, damaged strike plates, or non-rekeyable deadbolts require professional locksmith services for reliable fixes.
Overgrown landscaping and hidden entry points are easy and inexpensive to improve, significantly increasing perimeter visibility and reducing concealment spots.
Securing garage doors, removing visible keypads, and hiding remotes help prevent easy intrusions through commonly weak points.
Ensuring all exterior doors have properly extended deadbolts and reinforcing strike plates with longer screws enhances door resistance against forced entry.
Regularly testing alarms, routers, and surveillance devices, plus maintaining routine habits like locking up keys, keeps home security effective over time.

The at-a-glance checklist you can run in 20 minutes
Before you go room by room, run this fast pass. It catches the items that matter most if something happens tonight, and it tells you where the rest of the audit needs the most attention.
Are all exterior doors locked and do deadbolts fully extend into the frame?
Do smoke alarms test successfully when you press the button?
Has the Wi-Fi router password been changed from the factory default?
Are window locks engaged on every accessible window?
Is the garage door closed and the opener remote out of sight from cars?
Are house numbers visible from the street at night?
Do exterior lights turn on with motion or a timer?
Is there a carbon monoxide detector near sleeping areas?
For each item, mark Yes, No, or N/A. Photograph anything marked No so you remember the exact problem later, then assign an owner and a due date. Treat anything tied to fire, carbon monoxide, or a door that will not lock as immediate. Everything else, like a dim porch light or an unpruned hedge, can wait a week or two.
Perimeter and visibility: what to check outside the house
Stand across the street and look at your own house the way a stranger would. Sight lines matter as much as locks, since a hidden door or window buys an intruder time nobody else has.
Walk the property line and note any shrub or fence that blocks a clear view of doors and windows.
Confirm your house number is visible from the road, in a contrasting color, and lit at night so first responders can find you fast.
Check gates for working latches or locks, and make sure no gate blocks a path you would need for a quick exit.
Look for tall grass, stacked materials, or clutter near entry points that could hide someone at your door.
Overgrown landscaping is one of the most common findings in a home security checklist, and it is often the cheapest fix on the whole list. A weekend of trimming can close a gap that a locksmith visit cannot.
Exterior doors and locks: inspection checklist and when to call a locksmith
Every exterior door deserves a hands-on check, not just a glance. Push, pull, and wiggle each one while it is locked.
Check that the door fits the frame tightly with no visible gap at the strike side.
Test deadbolt throw: it should extend at least one inch into the frame.
Inspect hinges for rust, looseness, or exposed screws on the outside (a sign the door swings the wrong way for security).
Look at the strike plate: short screws or a thin plate are easy to kick through.
If a lock sticks, a key does not turn smoothly, or you inherited a house with unknown key copies floating around, that is a rekey job rather than a full replacement. If a frame is cracked, a strike plate is bent, or a deadbolt will not seat, that is a repair or install job. Specialized locksmith services handle residential rekeys, deadbolt and door lock installation, and lock repair, and a typical visit involves testing every affected lock, confirming fit, and leaving you with working keys the same day. For background on lock types before you call, this guide to door locks breaks down deadbolts and keyed entry options.
Pro Tip: Reinforce the strike plate with 3-inch screws that reach the door frame’s stud, not just the trim, for far better kick resistance.
Windows and sliding doors: quick tests and affordable barriers
Windows get less attention than doors, but they are just as often the point of entry. Test every lock, not just the ones you use.
Try to lift and slide each window while locked; a loose track lets it come off with minimal force.
Check sliding glass doors for a working lock plus a secondary bar or pin in the track.
Inspect older or single-pane windows for glazing that could be popped out without breaking glass.
Cheap fixes go a long way here: a track pin or dowel, a keyed sash lock, or security film on ground-floor glass. Do not overlook second-story windows near a tree, fence, or roofline, and remember that screens only keep bugs out, not people.
Garage, gates and outbuildings: closing common weak points
The garage is often the weakest link in an otherwise secure house, largely because homeowners treat it as storage rather than an entry point.
Confirm the door connecting the garage to the house locks and latches as securely as any exterior door.
Hide garage remotes and fobs from view inside parked cars.
Secure sheds and outbuildings with a quality padlock, and bolt down ladders or tools that could help someone reach an upper window.
Test the keypad or remote for reliability, and remove or cover any visible serial number or code sticker on the opener.
A side door that does not latch is one of the most frequent findings in garage security, and it is a quick fix; see this breakdown of garage side door fixes for specific steps you can do the same evening.
Lighting and landscaping: practical placement of motion lights and timers
Good lighting does double duty: it discourages anyone casing your property, and it makes your cameras actually usable at night.
Install motion-sensor lights at the front door, back door, and any side approach that is not visible from the street.
Set timers on interior and exterior lights when you travel, rather than leaving everything dark or everything lit.
Prune trees and hedges that reach upper-floor windows or block a camera’s view.
Test every exterior light once a season and confirm it runs on a circuit that will not trip during normal use.
Alarms, smoke and carbon monoxide detectors: placement, testing, and lifecycle
Fire and carbon monoxide safety belong in the same audit as intrusion checks, because a security fix that blocks an exit can be more dangerous than the break-in it was meant to stop.
Confirm smoke alarms are installed inside every bedroom, outside each sleeping area, and on every level of the home, including the basement.
Test each smoke alarm monthly and replace units at the end of their service life as the manufacturer specifies.
Check that security bars or gates on windows have a quick-release mechanism and do not block a planned escape route.
Verify your security system sends a notification you can actually see or hear, not just a silent log entry.
NFPA’s smoke alarm guidance recommends interconnected alarms so that one triggering sets off every unit in the house, giving occupants on every floor the same warning at the same time.
Cameras, monitoring and digital security: secure cameras, routers and accounts
A camera system is only as good as the network behind it, and most homeowners never touch the router settings that protect it.
Walk the property and confirm each camera’s field of view still covers its intended area, with no new obstruction from landscaping or parked vehicles.
Check that recordings are saving and notifications are reaching your phone, and confirm any subscription is active if your system requires one.
Change the router’s default username and password, enable its built-in firewall, and install any pending firmware update.
Disable WPS and remote management on the router unless you specifically need them, and turn on multi-factor authentication for your camera and alarm accounts.
The CISA home network guidance treats the router as the front door to every connected device in the house, which means a smart lock or camera is only as secure as the network it sits on.
Pro Tip: Cut power to your router for 30 seconds once a quarter, then confirm every camera and alarm reconnects and sends a test notification, so you know an outage will not leave you blind.
Household habits, valuables, keys and emergency planning
Hardware fixes half the problem. The rest comes down to routine.
Lock doors and windows every time you leave, even for a quick errand, and pause mail or deliveries when you travel.
Avoid posting travel plans on social media until you are back home.
Keep a photo inventory of valuables with serial numbers, and store key documents in a locked safe or off-site.
Walk your planned escape route with every household member, and adjust it for anyone with mobility limits, following the USFA’s older adult home fire safety guidance on audible and visible alarm access.
A daily habit checklist can help turn these into routine rather than something you remember only after a scare.
How to run and record the audit: sequence, table columns, prioritization and cadence
Walk the property twice, once during the day and once after dark, since problems like a dead motion light or a hidden approach path only show up at night. Photograph every defect as you find it and log it immediately rather than trying to remember it later.
Use a table with these columns for every item:
Re-run the full audit after a move-in, a renovation, a lost key, or any break-in attempt. Test alarms monthly and treat the full walk-through as an annual habit, per NFPA and USFA guidance on event-based and routine checks.
What I look for first when I walk a property
Doors and frames are where I start, since a weak strike plate or a soft frame defeats even a good deadbolt. Most of what I find is fixable in one visit: a loose hinge, a short screw, a lock that was never rekeyed after a move. Photograph what worries you and put a date on fixing it. A list without a deadline rarely gets finished.

When to call a locksmith and what Progressive Locksmith Cerrajero offers
Once your audit turns up a broken strike plate, a lock that will not rekey cleanly, or a deadbolt that never quite seats, that is the point where a locksmith visit closes the gap faster and more reliably than a hardware-store fix. Certain locksmith services match the most common audit findings directly.
Residential rekey when keys are unaccounted for or you just moved in.
Deadbolt and door lock installation for doors that failed the throw and strike test.
Lock repair for sticking latches, misaligned strikes, or worn cylinders.
Emergency house lockout service if you get locked out while making these fixes.
A typical visit starts with confirming the exact problem you documented, then testing the lock or door on-site before any work begins, so you know what is being fixed and why. If your audit list includes anything beyond what a single lock can solve, like access control for a rental property, the service page covering electronic and digital locks outlines those options too. Turn your dated action list into an appointment on the main services page and get it handled before it becomes an emergency call.
Primary sources behind this checklist
This checklist draws on the Bernards Township police checklist for its yes/no format, NFPA for alarm placement and testing, CISA for router and device security, and USFA for older-adult escape planning.

FAQ
What are the key items to include in a security audit checklist?
A thorough checklist covers perimeter and visibility, exterior doors and locks, windows and sliding doors, garage and outbuildings, lighting, alarms and detectors, cameras and digital devices, and household habits. Each item should be marked Yes, No, or N/A, following the structure used in police-style checklists, with every No turned into a dated action.
What are the recommended home safety checklists for seniors?
For older adults or anyone with mobility limits, the checklist should confirm alarms are both audible and visible, phones and mobility aids are reachable from the bed, and escape routes work with any assistive device in use. The USFA’s older adult fire safety guidance recommends prioritizing usability over adding more devices.
What are 7 general security tips?
Lock and reinforce exterior doors, secure windows and sliding doors, remove hiding spots with better lighting and trimmed landscaping, keep valuables and keys out of sight, test smoke and carbon monoxide alarms, secure your router and smart devices, and maintain a practiced emergency plan. These combine guidance from NFPA, CISA, and standard police checklist recommendations.
What does an audit checklist look like?
A usable audit checklist is a table with columns for area, specific check, Yes/No/N/A result, photo evidence, risk priority, recommended action, owner, and due date. This format, drawn from police-style checklists, turns a walk-through into a list of assigned tasks rather than a vague impression.
When should I call a locksmith instead of fixing something myself?
Call a locksmith when a deadbolt will not fully extend, a frame or strike plate is damaged, or you cannot account for all copies of a key. Progressive Locksmith Cerrajero offers residential rekey, deadbolt installation, and lock repair for exactly these situations, available through a quick call once your audit identifies the problem.
