Home theft is a crime of opportunity. Burglars pick houses where entry looks easy and the risk of being seen is low, so the properties that get broken into are the ones that look unguarded. The FBI counted about 1.2 million burglaries in the United States in 2019, roughly 60 percent residential, with a typical loss near $2,700.
Most entries happen through doors and first-floor windows during daylight hours, when the house looks empty. The defenses that matter are the ones you keep up every day, and they belong on the same seasonal checklist as the essential steps to prevent frozen pipes and protect your home this winter.
The layers of home security below appear in the order you should add them: doors and windows, locks, cameras and lighting, valuables, keys, the garage, and the signals that make a house look occupied.
Secure the Doors and Windows
Locking all the doors and windows is the first step, and the one most often skipped. A burglar casing a neighborhood checks for an open window, a sliding door left unlocked, or a side door with a flimsy latch. Every entry point needs a working lock and a habit of using it, even during the day.
Entry Points Burglars Test First
Burglars prefer the back door, the garage service door, and first-floor windows, all out of sight from the street. Sliding glass doors are a favorite because the latch is easy to pop; a dowel or metal bar in the track blocks the door even if the lock fails.
- Solid-core or metal exterior doors, not hollow-core
- Deadbolts on all exterior doors, including the garage service door
- Strike plates fixed with 3-inch screws into the door frame
- Secondary locks or pins on sliding doors and windows
- Window locks that engage, checked twice a year
Reinforce the Door Frame
A deadbolt is only as strong as the strike plate and the wood behind it. The 1-inch screws that ship with a lock set pull out under a hard kick, while 3-inch screws reach into the wall stud and hold the door closed. Reinforced strike plates and hinge-side pins close the remaining weak points.
Smart Locks and Entry Sensors
Smart locks replace the key with a keypad code, a phone app, or a fingerprint, and the useful feature is the audit trail: the lock records who came in and when, and it can auto-lock behind you. Entry sensors feed the same system, so a door opened while you are away triggers the alarm and a phone notification.
Electronics bring their own risks, because a camera or smart lock that dies in a storm is one you cannot rely on. Protecting the gear starts with the same rules that prevent lightning damage to your home: grounding the panel and surge protectors on network equipment.
Upgrade Locks and Make the House Look Occupied
Old locks are not good enough. A worn cylinder, a deadbolt missing, or a lock keyed alike with a dozen other houses gives a burglar a reason to test it. Rekeying after you move in costs little compared with knowing who holds keys to your door.
Deadbolt Grades and Pick Resistance
ANSI grades locks by how hard they are to break: Grade 1 is the strongest and rated for commercial use, Grade 2 suits residential entry doors, Grade 3 is the minimum for interior use. Anti-pick pins and bump-resistant cylinders slow the tools burglars carry, and a hard lock usually gets skipped for an easier house.
Make the House Look Occupied
Burglars avoid houses that look lived in. Timers that switch lamps at realistic hours, a radio left on, a car in the driveway, and mail collected by a neighbor all signal activity. The effect works best when the routine is unpredictable, because a light that snaps on at exactly 6 p.m. every night reads as a timer.
The occupied-house trick is one of the oldest and cheapest defenses, and it goes further than lamps. Bob Vila’s advice on how to prevent break-ins by faking being home covers the details that sell the illusion, from the rooms that should stay lit to a cleared driveway and mowed lawn.
| Lock type | Security level | Typical cost | Best use |
|---|---|---|---|
| Single-cylinder deadbolt | Good | $20-$60 | Exterior doors |
| Double-cylinder deadbolt | High, key needed both sides | $30-$80 | Doors with glass nearby |
| Smart lock with keypad | High, plus audit log | $100-$300 | Entry doors and rentals |
| Keypad entry lock | Good | $40-$120 | Garage service door |
| Sliding door lock or bar | Good | $10-$40 | Sliding glass doors |
Key Control and Spares
Every spare key is a risk. The flowerpot, the doormat, and the fake rock are the first places a burglar checks, so keep spares with a trusted neighbor or in a lockbox bolted out of sight. After a move, rekey every exterior lock, because you cannot know how many copies of the old key exist.
- Remove the old latch, cylinder, and strike plate
- Install the new deadbolt cylinder and latch per the manufacturer template
- Set the strike plate and drive 3-inch screws into the wall stud
- Test the lock with the door open, then with the door closed
- Confirm the latch throws fully and the key or code turns it smoothly
Install a Security System and Outdoor Lighting
Cameras and lighting work as a pair: a camera records the face of anyone who approaches, and a light removes the darkness burglars rely on, because a camera pointed into the dark is blind.
Camera Placement
Cover the front door, back door, driveway, and any side gate. Mount cameras 8 to 10 feet up and angled down so faces are captured instead of hat brims, and choose units with night vision and 1080p resolution. A visible camera deters; a hidden one only documents.
Outdoor Lighting
Most theft happens at night because darkness hides movement. Motion-activated floodlights at the corners light up anyone approaching, dusk-to-dawn lights keep the yard visible all night, and timers keep indoor lamps on a schedule when you are out. Lights also improve camera footage.
| Light type | Trigger | Power use | Best location |
|---|---|---|---|
| Motion floodlight | Movement in range | Low, short bursts | Corners, garage, back door |
| Dusk-to-dawn | Darkness | Moderate, all night | Driveway, front yard |
| Timer lamps | Set schedule | Low | Indoor rooms |
| Smart lights | App, schedule, sensors | Low | Indoor and outdoor |
| Solar path lights | Darkness | None from the grid | Walkways, side yards |
Alarm Systems and Monitoring
A monitored alarm adds the human response: sensors on doors and windows, motion detectors, and a call to police when the alarm trips. DIY systems with cellular backup cost less than professional installation, and many run without a monthly fee. Put the yard signs up either way, because the deterrent works before the alarm sounds.
Cameras only help if the yard stays visible, and overgrown shrubs create hiding spots next to doors and windows. The same seasonal walk-around that checks the cameras clears the clutter that attracts pests; the routine for identifying, preventing, and eliminating brown recluse spiders from your home is the tidy-perimeter habit that keeps sight lines open.
Hide Valuables, Keys, and the Garage
Burglars are in a hurry. They head for the master bedroom, the home office, and visible electronics, and they grab what fits in a bag. The goal is to make the grab slow and unrewarding.
Store Valuables Out of Sight
Keep jewelry, documents, cash, and small electronics out of the master bedroom closet, the first place burglars look. A bolted-down safe adds minutes to the job, usually enough to make a burglar leave. Bikes and power tools belong locked or out of sight, not in an open garage where they advertise themselves.
Hiding Places for Keys
The doormat, the flowerpot, and the plastic rock are known hiding spots, so do not use them. Leave a spare with a trusted neighbor or friend, use a combination lockbox mounted where it cannot be seen from the street, or keep the spare in a locked drawer somewhere you control.
Garage Security
The garage is a second front door, and the interior door between garage and house is often the weakest lock in the home. Keep the garage door closed and locked, cover the emergency release so a thief cannot pop it with a coat hanger, and treat the service door like a main entrance. The opener remote lives in the house, not the car.
- Jewelry and cash in a bolted-down safe, not the closet
- Serial numbers and photos of electronics stored in the cloud
- Bikes, tools, and lawn equipment locked or out of sight
- Ladder stored inside or chained, not against the house
- Spare keys with a trusted person or lockbox, never under the mat
Protecting possessions goes beyond what sits inside the walls, because the house itself can be stolen on paper. Home title theft is a property fraud in which a criminal files a forged deed transfer, and prevention means checking county records, freezing credit, and guarding personal documents, all cheap compared with the legal fight to get a title back.
Build Neighborhood-Level Defenses
Houses on blocks where neighbors watch out for each other get broken into less often. Anything that makes the street feel observed pushes burglars elsewhere.
Neighborhood Watch and Community Habits
A neighborhood watch group formalizes what good neighbors already do: watch for unfamiliar vehicles, note unusual activity, and call the police instead of assuming someone else will. Knowing your neighbors’ routines makes it obvious when something is off next door.
Landscaping and Sight Lines
Trim shrubs below window height, prune tree limbs that reach second-floor windows, and keep the yard clear so nobody can hide between the street and the door. Thorny plants under windows are a classic deterrent, and gravel paths and beds make footsteps audible at night.
The defenses that protect the house while you are away cover more than crime. A long trip leaves the plumbing at risk too, and the pre-travel checklist that secures the doors should include steps to prevent frozen pipes and protect your home from winter water damage, because a burst pipe does as much harm in a week as a burglar does in ten minutes.
None of this holds if the house itself is falling apart, because a door that sticks, a frame that rots, and a latch that no longer lines up are invitations. practical home repair techniques that prevent structural damage keep the envelope tight, the doors square, and the locks aligned, and that maintenance is the base every other security layer sits on.
