If you want a practical home security checklist Chicago homeowners can actually work through in a weekend, this is it. Instead of vague advice like “install better locks,” this guide walks your property room by room, from the front door to the basement, with specific hardware, distances, and habits that stop most break-ins before they start. It is written for Chicago homeowners, renters, and condo owners who want a clear plan rather than a scare piece.
The Professional Locksmith has served Chicago since 2012 as a licensed, bonded, and insured company with Certified Registered Locksmiths on staff. We built this checklist from thousands of real service calls across neighborhoods like Avondale, Lincoln Park, and the West Loop.
Key Takeaways
Most residential break-ins happen through the front or back door, so start your home security checklist there.
A Grade 1 deadbolt with a 1-inch throw and 3-inch screws in the strike plate resists roughly 90 percent of kick-in attempts.
Ground-floor and alley-facing windows are the second most common entry point in Chicago two-flats and garden units.
Layered security (locks, lighting, cameras, and habits) beats any single expensive gadget.
A professional security audit can identify weak points you cannot see, and often takes under an hour.
Start at the Front Door: Your First Line of Defense
According to the FBI Uniform Crime Reporting program, a large share of home burglaries involve forced entry through a main door. Your front door is where a Chicago home security checklist should always begin.
Deadbolts, Strike Plates, and Screws
Check that every exterior door has a deadbolt rated Grade 1 or Grade 2 by ANSI/BHMA standards. A quality deadbolt should have a full 1-inch bolt throw. Just as important is the strike plate: replace the standard 3/4-inch screws with 3-inch screws that anchor into the wall stud, not just the door jamb. This single upgrade, which costs only a few dollars in parts, dramatically increases kick-in resistance.
If your locks are more than 15 years old, or if you have moved in within the last year and never changed them, consider a lock change or rekey. Our lock installation service and high security locks installation cover Grade 1 hardware and pick-resistant cylinders.
Reinforce the Frame and Add a Latch Guard
Chicago has many vintage two-flats and greystones with original wood door frames that split under force. A door frame reinforcement kit or a full-length latch guard protects the vulnerable area around the lock. We install these through our latch guard installation service, and they are especially valuable on out-swinging or alley-facing doors.
See Who Is There
Add a wide-angle peephole or a video doorbell so you never open the door blind. For renters, a peephole is a landlord-friendly upgrade that leaves no wiring behind.
Back Doors, Side Doors, and Garages
Burglars prefer entry points that neighbors cannot see. In Chicago, that usually means the back door off the porch, a gangway side door, or the garage.
Back and Side Doors
Give every secondary door the same treatment as the front: a Grade 1 deadbolt, reinforced strike plate, and 3-inch screws. Sliding patio doors need a secondary bar or a pin lock in the track, because the factory latch alone can often be lifted off its rail. A dowel cut to fit the track costs almost nothing and blocks the door from sliding.
The Attached or Detached Garage
Many Chicago homes have a detached garage off the alley, which is a frequent target for tool and bike theft. Steps to take:
Install a deadbolt on the garage service door, not just the handle lock.
Frost or cover garage windows so contents are not visible.
Never leave the garage door opener in an unlocked car parked outside.
If your garage connects to the house, treat that connecting door as an exterior door with a deadbolt.
Windows: The Overlooked Entry Point
Ground-floor windows, garden-unit windows, and windows near fire escapes are the second most common way intruders get in. Work through every accessible window on your home security checklist.
Locks, Pins, and Sensors
Double-hung windows should have working sash locks. For extra security, drill a small hole and insert a window pin or nail that lets you set the window in a slightly open, ventilated position without allowing it to be raised further. Basement and garden-unit windows deserve extra attention because they sit at ground level in an alley.
Balance Security With Fire Safety
The National Fire Protection Association warns against permanently barring or nailing windows shut, because at least one window in every sleeping room must work as an emergency escape. If you use security bars, choose interior quick-release models. Safety and security must coexist.
Layer in Technology: Cameras, Lighting, and Smart Locks
Locks stop entry, but visibility and deterrence keep your home off a burglar’s list in the first place.
Security Cameras
A visible camera at the front and rear entrances is one of the strongest deterrents you can add. Position them to cover the door, the walkway, and any package drop area. We design and install professional systems through our security cameras service, which is useful for multi-unit buildings and homes where DIY cameras leave blind spots.
Exterior Lighting
Motion-activated lighting at every entry point removes the darkness a burglar depends on. Aim for coverage of the front walk, the back porch, the gangway, and the alley approach to the garage.
Smart Locks and Keyless Entry
Keypad and smart locks eliminate the hide-a-key under the mat and let you issue temporary codes to dog walkers, cleaners, or guests. They also solve the “who has a copy of my key” problem. See our keyless entry systems options for weatherproof models that hold up in Chicago winters.
Habits and Chicago-Specific Considerations
Hardware only works if you use it. The following habits close the gap between having locks and being secure.
Everyday Habits
Lock every door and window, even when home and even for a quick errand.
Never post vacation plans publicly until you return.
Break down large delivery boxes (for TVs, electronics) inside, not at the curb.
Keep a spare key with a trusted neighbor, not hidden outside.
Apartment, Condo, and High-Rise Notes
Renters: your Chicago landlord is generally responsible for providing working locks. Request a rekey when you move in.
Condo owners: check whether your HOA controls the building entry and intercom system before upgrading.
High-rise residents: your unit door and the building buzzer system are your two key layers. A modern intercom installation protects the whole building’s front entrance.

Frequently Asked Questions
What is the single most important home security upgrade?
A Grade 1 deadbolt secured with 3-inch screws into the wall stud gives the biggest security return for the lowest cost. It hardens your most common entry point, the main door, against kick-ins. Pair it with a reinforced strike plate for the best result.
Do I really need to change locks when I move into a Chicago home?
Yes. You have no way of knowing how many copies of the old keys exist with previous tenants, contractors, or real estate agents. A rekey or lock change on move-in day is inexpensive peace of mind and should be first on your checklist.
Are security cameras worth it for a single-family home?
Yes, especially for package theft and rear-entry deterrence. Visible cameras discourage opportunistic burglars, and footage helps police if an incident occurs. Professional placement removes the blind spots that cause most DIY systems to miss the actual entry point.
How much does a professional home security audit cost in Chicago?
Costs vary by home size and scope, and many locksmiths fold an assessment into a service visit. A typical residential walkthrough takes under an hour. Call The Professional Locksmith at (312) 796-0901 for current pricing and a room-by-room evaluation.
Can renters improve security without violating the lease?
Yes. Peepholes, window pins, portable door bars, and plug-in cameras leave no permanent changes. For lock changes, ask your landlord to authorize a rekey, which Illinois landlords commonly arrange between tenants.
Conclusion: Turn This Checklist Into an Action Plan
A complete home security checklist Chicago homeowners can trust does not depend on one expensive gadget. It layers hardened door hardware, secured windows, smart lighting, cameras, and everyday habits so that no single weak point invites a break-in.
