Living alone is great. Anyone who’s done it knows the distinct pleasure of coming home to a place that’s exactly the way you left it, eating cereal for dinner without anyone judging, and watching whatever you want without negotiation.

It also means your home security is entirely on you. There’s no second person to notice that the back door isn’t quite latched or that the porch light has been out for a week. So a few specific habits and hardware investments make a meaningful difference for solo homeowners and renters.

These are the 15 tips we recommend most often, organized roughly in order of impact-per-dollar.

The big-impact basics (1–5)

1. Rekey on day one of any new place

The single highest-ROI security move when you move into a new home or apartment. You have no idea who has copies of your keys — the previous tenant, their cleaner, their ex, their handyman, the realtor’s lockbox, the neighbor who watched their cat. Rekey costs $25–$45 per lock and invalidates every existing key. Do it before you unpack.

For renters: ask your landlord. Most will agree, especially if you offer to pay. Some leases require landlord-arranged rekeying — read yours.

See our rekey vs. lock change guide for the full decision framework.

2. Reinforce the front door strike plate

Most kicked-in residential doors fail at the strike plate, not the lock. Replace the short screws (usually 3/4 inch) that came with your deadbolt with 3-inch wood screws that reach the framing studs behind the jamb. Cost: $5 in screws, 10 minutes with a drill. This single upgrade defeats the most common forced-entry attack on residential doors.

3. Install a smart lock with a keypad

Single biggest quality-of-life upgrade for solo living. With a keypad smart lock you can:

Stop carrying keys
Give time-limited codes to dog walkers, cleaners, or houseguests without ever handing out a physical key
Get a phone notification every time someone enters
See a log of who entered and when

Brands we install most often: August, Yale Assure, Schlage Encode, Kwikset Halo, Level. See our smart lock buyer’s guide for details.

4. A doorbell camera, even a basic one

You don’t need the most expensive system. A Ring, Nest, or Eufy doorbell camera that records when motion is detected and lets you see who’s at the door from your phone — even when you’re home alone in the back of the apartment — is a major security and peace-of-mind upgrade. $100–$200, one-time.

5. Two-step verification on every account that supports it

Not strictly home security, but: if your phone, email, banking, and home camera accounts get compromised, your physical security can follow. 2FA on every account that supports it (Authy, Google Authenticator, hardware key — not SMS if you can avoid it) is the digital equivalent of a deadbolt.

Habits that compound (6–10)

6. Always lock up — even for “just a minute”

The classic mistake. Walking the dog at 7am, leaving the door unlocked because “I’ll be right back.” The five minutes you’re at the corner are all an opportunist needs. Lock up every time, even when you can see the door from the sidewalk.

7. Don’t broadcast that you’re alone

This isn’t paranoia, it’s reasonable habit:

Don’t list your full name + apartment unit on the door buzzer if you can avoid it (initials work fine)
Don’t post on social media that you live alone
Don’t post real-time vacation photos — wait until you’re home
For deliveries, “Sign for John Smith” is fine; “Sign for John, who lives alone in apartment 4B” is not

8. Use the second car / second pair of shoes / second light trick

If you live alone but want to look like you don’t:

A pair of large boots near the front door (visible through the peephole or sidelight) creates the suggestion of a second resident
Smart bulbs set to turn on/off in different rooms on a varied schedule create the appearance of an active home when you’re traveling
A spare car parked in the driveway (yours or a neighbor’s, with permission) suggests two adults

These are theater, but theater works on opportunists. Determined burglars do reconnaissance — opportunists pick the easiest house on the block.

9. Get to know your neighbors

The single most underrated security investment. Neighbors who know your habits, know your car, know when you’re home, and know to call you (and 911) when something seems off are worth more than any individual piece of hardware.

Bring cookies. Help with their packages. Mention your work schedule in passing. This is what neighborhood watch actually means in 2026.

10. Put one spare key with someone you trust — never under a rock

The “spare key under the doormat / in the fake rock / above the doorframe” — burglars know every hiding spot. Either give one labeled spare to a neighbor or family member, or use a wall-mounted lockbox with a code you can change. Or use a keypad smart lock and skip the spare key problem entirely.

Tech worth the money (11–13)

11. A smart home hub or simple automation routines

Even basic routines pay off:

“When I leave home” automation that turns off lights and arms cameras
“When I arrive home” automation that turns on entry lights so you’re not fumbling in the dark
“Vacation mode” that randomizes interior lights to look occupied

You don’t need a fancy hub. Apple Home, Google Home, Amazon Alexa routines, or any Wi-Fi smart bulb app will do this.

12. Motion-sensor outdoor lighting at every entrance

$30–$80 per fixture, easy DIY install if you already have an outdoor electric box. Eliminates dark approaches and surprises whoever might be near your door at night. Surprisingly effective deterrent — most opportunists won’t proceed when they’re suddenly lit up.

13. A fireproof + waterproof lockbox or small home safe

Not for valuables (large safes are a separate conversation — see our safe locksmith service). For documents — passport, social security card, birth certificate, insurance papers, copies of important keys. $50–$200 buys a fire-rated, water-resistant document safe that lives in a closet. Solo living means you are the document custodian; treat the role seriously.

What to do if something happens (14–15)

14. Make a “what to do” list before you need it

Tape it inside a kitchen cabinet:

Local police non-emergency number
Your locksmith’s number
Two emergency contacts who can come over
The address and crossroads of your home, in case panic makes you blank

We see customers locked out at 2am unable to remember their own street name. Pre-written, where you can find it without unlocking your phone, matters.

15. Know what to do in a lockout

If you’re locked out:

Step 1: Take a breath. You are not in danger.
Step 2: Check every door and window before calling. Not unusual to find one unlocked.
Step 3: If you have a roommate, partner, or family member with a copy, call them.
Step 4: If not, call us (or your local locksmith). Average lockout costs $95–$185, takes 15–45 minutes from dispatch to inside.

If you’re locked out late at night, the right call is to find a safe, lit, public place to wait (24-hour diner, hotel lobby) while you arrange help. Don’t sit alone in a dark parking lot.
