How to Set Up a Simple Home Security Routine in 4 Steps

TL;DR: A monthly security routine—checking locks, exterior lighting, door hardware, and window latches—reduces break-in risk by 60% according to Department of Justice data. Most tasks take 5 minutes or less and catch issues before they become vulnerabilities. Document each check with photos; Okoniq Property Hub timestamps every note so you have a dated record if an insurance claim or tenant question arises.

Most break-ins happen through unlocked doors or windows with faulty latches, not through movie-style safecracking. A simple monthly walk-through catches 90% of these entry-point weaknesses before they're exploited. The routine below takes 30-45 minutes per property and costs nothing except the price of a few replacement bulbs or screws.

Okoniq Property Hub logs each security check with a date stamp, photo attachments, and location tags—helpful when you manage multiple units or need to show a tenant you replaced a broken deadbolt on a specific date.

What should I check first: locks or lighting?

Start with exterior lighting after dark. Walk the perimeter and note any burned-out bulbs, fixtures that don't turn on, or motion sensors that fail to trigger. Department of Justice studies show well-lit entry points deter 80% of opportunistic break-ins—thieves avoid properties where neighbors can see them clearly.

Replace any dead bulbs within 48 hours. LED bulbs rated for outdoor use last 15,000-25,000 hours (roughly 5-10 years at 6 hours per night) and cost $3-8 each. If a fixture flickers or stays dark after a new bulb, the socket or wiring needs attention; call an electrician for anything hardwired. Motion-sensor lights should trigger at 15-20 feet; adjust the range dial on the fixture if the sensor is too sensitive or too slow.

Document each fixture location and bulb replacement date. Tenants often report "the porch light is out" without specifying which one; photos in your maintenance log remove the guesswork. For properties with multiple outdoor lights, consider scheduling a ceiling light fixture replacement or upgrade to weatherproof LED fixtures with built-in dusk-to-dawn sensors—they cost $25-50 and eliminate the need to remember to turn lights on.

How do I test door locks and deadbolts properly?

Lock and unlock every exterior door from both sides using the key and the interior thumb-turn. A deadbolt should slide smoothly with one finger of pressure; any grinding, sticking, or key wiggling means the lock needs lubrication or the strike plate is misaligned. Spray a Teflon-based lock lubricant (not WD-40, which attracts dirt) into the keyway twice a year, or whenever you feel resistance.

Check that the deadbolt extends at least 1 inch into the door frame when locked. Anything shorter is vulnerable to kick-ins. If the bolt barely clears the door edge, the strike plate may have shifted—remove the plate and chisel the mortise deeper, or add a 3-inch screw through the plate into the wall stud. Grade 2 deadbolts ($40-70) meet ANSI/BHMA standards and resist 5 strike attempts; Grade 1 ($80-150) is commercial-grade and handles 10.

Inspect door hinges next. If hinge pins are accessible from outside, install non-removable pin hinges or hinge studs—a thief can pop standard pins in 30 seconds with a hammer and screwdriver. Tighten any loose hinge screws and replace short screws with 3-inch versions that reach the wall stud. For rental properties, photograph the lock brand and model so you can rekey quickly if a tenant loses keys.

What window and sliding-door checks prevent easy entry?

Test every window latch by locking it, then trying to lift or slide the sash from outside (if accessible). Older single-hung windows often have worn cam locks that don't engage fully; replace them with keyed sash locks ($8-15 per window) or install a secondary pin lock in the top rail. Sliding windows and patio doors should have a security bar or dowel in the track—a 1-inch wooden dowel cut to length costs $2 at a hardware store and stops forced sliding.

Check that window screens are intact and secured with clips or screws. A missing or loose screen signals an unoccupied unit to passersby. For ground-level windows, consider planting thorny shrubs (barberry, holly, or roses) 2-3 feet from the glass—Department of Justice data shows landscaping obstacles reduce window break-ins by 40%. Avoid tall shrubs that provide cover; keep foundation plantings under 3 feet.

Sliding glass doors are a common weak point. The factory latch on most doors is a cam lock that can be jimmied with a screwdriver. Add a floor-mounted Charlie bar or a Charley Bar-style brace ($15-30) that wedges between the door and the frame. For older aluminum-frame sliders, lift the door panel up and off the track to check that the anti-lift blocks are in place—these are small brackets at the top of the frame that prevent the door from being lifted out. If they're missing, install them with screws into the header.

How often should I update access codes and rekey locks?

Change any electronic keypad codes or smart-lock PINs every 6 months, or immediately after a tenant moves out or a contractor finishes a long project. Default codes (0000, 1234, or the last four digits of the address) are the first thing a thief tries; use a random 4- or 6-digit code and write it down in your maintenance log rather than storing it in a phone note labeled "house code."

Rekey locks whenever you take possession of a property, even if the previous owner swears no one else has keys. A locksmith can rekey a deadbolt and entry knob for $20-40 per door, or you can buy a rekeying kit ($15-25) and do it yourself if all locks are the same brand (Kwikset and Schlage kits are widely available). For multi-unit properties, consider a master-key system so you carry one key but tenants have individual keys—costs $50-100 per building to set up.

If you use a lockbox for contractor access, change the combination monthly and remove the box entirely when no service is scheduled. Lockboxes advertise vacancy or predictable access patterns. For long-term contractors, issue a temporary code on a smart lock and delete it the day the job finishes. Smart locks with activity logs (August, Yale, Schlage Encode) record every unlock event with a timestamp, which is useful if tools or materials go missing during a rehab.

Should I install cameras or alarm systems?

Visible cameras deter 67% of burglars according to a UNC Charlotte study of convicted burglars. You don't need a $2,000 system—battery-powered cameras like Ring Stick Up Cam ($100) or Wyze Cam Outdoor ($50) send motion alerts to your phone and record clips to the cloud for $3-10/month. Mount one camera at the front door and one at the back or garage entry; side windows are less common entry points unless they're hidden from the street.

Angle cameras to capture faces at 5-6 feet high, not just the top of someone's head. Adjust motion zones so you're not flooded with alerts every time a car drives by or a tree branch sways. For rental properties, disclose camera locations in the lease—tenants have a reasonable expectation that entryways are monitored, but cameras must never point into windows or private areas.

Alarm systems add a second layer. Basic monitored systems (SimpliSafe, ADT Self Setup) cost $15-25/month and include door/window sensors, a motion detector, and 24/7 professional monitoring. If a sensor trips and you don't disarm within 30 seconds, the monitoring center calls you, then dispatches police if you don't answer. Self-monitored systems (no monthly fee) send alerts to your phone but don't call authorities—fine if you're local and can respond in 10 minutes, less useful if you manage properties remotely.

Place "security system" yard signs and window decals even if you only have cameras or no system at all—the UNC study found 60% of burglars avoid homes with alarm signage. Generic "This property is monitored" signs ($8 on Amazon) are legal and effective without requiring an actual contract.

FAQ

How long should a full security check take per property?

30-45 minutes for a single-family home with 3-4 exterior doors, 10-15 windows, and basic lighting. Multi-unit buildings take 15-20 minutes per unit if you're checking only the unit entry and shared exterior doors. Schedule checks monthly or quarterly depending on vacancy rate and neighborhood.

Do I need to check security more often if a property is vacant?

Yes. Vacant properties are 5x more likely to be broken into according to insurance industry data. Walk the perimeter weekly, vary your arrival time so you're not predictable, and leave lights on timers in 2-3 rooms. If you manage a seasonal property, have a neighbor or property manager do a visual check every 3-5 days during the off-season.

Can I deduct security equipment as a rental expense?

Cameras, locks, alarm monitoring fees, and motion-sensor lights are deductible as maintenance or operating expenses on Schedule E if the property is a rental. Equipment under $2,500 per item qualifies for the de minimis safe harbor (immediate deduction); over that, you depreciate it over 5-7 years. Talk to a CPA about your specific situation, especially if you're installing a full alarm system with installation costs over $1,000.

What's the best way to secure a basement or crawl space entry?

Install a hasp and padlock on exterior bulkhead doors or crawl-space hatches. Use a shrouded padlock (the shackle is partially covered) rated weatherproof and cut-resistant—ABUS and Master Lock make versions for $15-30. For interior basement doors leading to shared or unfinished areas, add a deadbolt or slide bolt if tenants have access. Check that basement window wells are clear of debris and that the window locks work—thieves know these entry points are often overlooked.

Should I give tenants a copy of the security routine checklist?

Share a simplified version: remind them to test locks monthly, report burned-out exterior bulbs within 24 hours, and keep ground-floor windows locked when they're away. Don't share details about camera blind spots, alarm codes, or where you hide spare keys. For single-family rentals, include a clause in the lease requiring tenants to maintain working batteries in smart locks or to notify you if a lock becomes stiff or difficult to operate.
