7 Critical Home Security Mistakes Boston Homeowners Make (And How to Fix Them Today)
After serving hundreds of Boston homeowners across neighborhoods from Beacon Hill to Jamaica Plain, we've noticed a troubling pattern. Many residents invest in alarm systems and security cameras while overlooking fundamental vulnerabilities that burglars exploit daily. The truth is, most break-ins succeed not because of sophisticated techniques, but because homeowners unknowingly leave their properties exposed through common security mistakes.
As a trusted Boston locksmith company, we've been called to homes after break-ins where a simple $50 fix could have prevented thousands in losses and irreplaceable emotional distress. This guide reveals the seven most dangerous security mistakes we encounter and provides professional solutions you can implement immediately to protect your family and property.

Mistake #1: Using the Same Locks from the Previous Owner
When you move into a new home in Boston, whether it's a historic brownstone in Back Bay or a triple-decker in Dorchester, you're trusting that previous keys are accounted for. But here's the reality: former owners may have distributed keys to contractors, house cleaners, dog walkers, neighbors, and family members over the years. Even with the best intentions, not everyone returns their copy.
The Hidden Risk
We've responded to emergency lockout calls where homeowners discovered their "new" home had been entered by someone with an old key. In one recent case in Cambridge, a homeowner found items missing weeks after moving in—the previous owner's contractor still had a key and assumed the house was vacant.
The Professional Solution
Rekeying your locks should be the first task after closing on any property. Our residential locksmith services can rekey all your door locks in a single visit, usually within a few hours. This service costs a fraction of replacing all hardware and gives you complete control over who has access to your home. We recommend rekeying:
- All exterior door locks
- Garage door entry points
- Basement access doors
- Any locks on gates or fence entries
For multi-unit properties or larger homes, consider a master key system that gives you access to all locks with one key while maintaining separate keys for different areas—perfect for rental properties or in-law apartments.
Mistake #2: Relying on Outdated Lock Technology
Many Boston homes, particularly in older neighborhoods like the South End or Charlestown, still use lock cylinders installed decades ago. While these vintage locks have charm, they often use pin tumbler technology that experienced burglars can pick in under a minute. We've tested this ourselves during security assessments—older locks offer minimal resistance to modern lock-picking tools or bump keys.
What Makes Modern Locks Superior
Today's high-security locks incorporate features that didn't exist twenty years ago. Grade 1 deadbolts feature hardened steel bolts, anti-drill plates, and pick-resistant cylinders. Some advanced systems include:
- Sidebar technology that prevents traditional picking methods
- Hardened steel inserts that resist drilling attacks
- Anti-bump pins that neutralize bump key techniques
- Free-spinning cylinders that defeat forced-entry tools
The Investment That Pays Off
Upgrading to modern, high-security locks is one of the most cost-effective security improvements you can make. Our lock replacement services include a full security assessment to identify your most vulnerable entry points. Most homeowners are surprised to learn that upgrading their three main exterior locks costs less than a single month of their home insurance premium—yet significantly reduces their break-in risk.
For Boston homeowners concerned about maintaining historic aesthetics, we offer solutions that preserve the vintage appearance of your hardware while incorporating modern security technology inside the lock mechanism.
Mistake #3: Neglecting the Back Door and Side Entrances
Walk through any Boston neighborhood and you'll notice impressive front doors with high-quality locks and deadbolts. Then check the back door—often secured with a flimsy lock or, worse, a decades-old knob lock that provides minimal security. Burglars know this pattern well. According to FBI statistics, 34% of burglars enter through the back door, specifically targeting these weaker entry points.
The Oversight Most Homeowners Make
During security consultations, we routinely find back doors protected only by a simple knob lock—sometimes without any deadbolt at all. Other common vulnerabilities include:
- Glass panels within arm's reach of the lock
- Sliding doors with inadequate securing mechanisms
- Basement bulkhead doors with simple padlocks
- Side doors hidden from street view by fencing or landscaping
Comprehensive Door Security
Every exterior door deserves the same level of protection. We recommend installing commercial-grade deadbolts on all entry points, including:
- Grade 1 deadbolts: The highest residential security rating, featuring one-inch bolts and hardened steel construction
- Reinforced strike plates: Extended strike plates with 3-inch screws that anchor into wall studs, not just the door frame
- Door reinforcement kits: Steel plates that strengthen the area around locks and prevent kick-in attacks
For doors with glass panels, consider installing double-cylinder deadbolts that require keys from both sides. While these require careful use (keep a key accessible for emergency exits), they prevent intruders from breaking glass and reaching inside to unlock the door.
Mistake #4: Leaving Sliding Doors Vulnerable
Sliding glass doors are popular in Boston homes, offering access to decks, patios, and yards. Unfortunately, the standard locks on most sliding doors provide minimal security. Many can be lifted off their tracks or jimmied open with a simple screwdriver. We've demonstrated this vulnerability to countless homeowners who were shocked at how quickly their "locked" sliding door could be breached.
The Sliding Door Security Problem
Standard sliding door locks engage a small hook into the door frame—a design that offers convenience but limited security. Additionally, older sliding doors can often be lifted and removed from their tracks, bypassing the lock entirely.
Multi-Layer Protection Strategy
Securing sliding doors requires a comprehensive approach:
- Security bars or Charlie bars: These adjustable bars sit in the track and physically prevent the door from sliding open, even if the lock is compromised
- Pin locks: Install pins that drop through holes drilled in the sliding door frame into the fixed frame below, preventing movement
- Upgraded locks: Replace factory locks with aftermarket security locks that engage deeper into the frame
- Track guards: Install blocking devices that prevent the door from being lifted off its track
- Security film: Apply window security film to the glass, making it extremely difficult to break through
Our lock repair and installation services include sliding door security upgrades that transform your most vulnerable access point into a formidable barrier against intrusion.
Mistake #5: Poor Key Management and Obvious Hide-A-Keys
We've all been locked out and wished we had a spare key hidden somewhere. Unfortunately, burglars know every common hiding spot: under the doormat, above the door frame, inside fake rocks, under flower pots. During security consultations, we've found spare keys in "hiding spots" within seconds—if we can find them, so can experienced criminals.
The Key Copy Risk
Beyond hidden keys, loose key management creates multiple vulnerabilities:
- Keys left in obvious places (kitchen counter, by the door) where they're visible through windows
- Keys labeled with addresses or identifiable information
- Giving unrestricted key access to service providers without tracking or time limits
- Using the same key for multiple properties, multiplying risk
Modern Key Management Solutions
Smart homeowners are moving beyond hide-a-keys to more secure solutions:
Keyless Entry Systems: Modern smart locks eliminate the need for hidden keys entirely. These systems allow you to:
- Provide temporary access codes to service providers that expire automatically
- Grant remote access to family members when needed
- Track who enters and when through your smartphone
- Change access codes instantly if security is compromised
Restricted Keyway Systems: For homeowners who prefer traditional keys, restricted keyway systems provide enhanced security. These specialized locks use patented key designs that can only be duplicated by authorized dealers with proper identification. This prevents unauthorized key copying and gives you complete control over your home's access.
Key Tracking Protocol: If you must distribute physical keys, maintain a written log of who has keys and for what purpose. Collect keys immediately when service relationships end, and consider rekeying after contractors complete major projects.
Mistake #6: Ignoring Window Security
While homeowners focus on door locks, windows remain a primary entry point for burglars. Ground-floor windows and basement windows are particularly vulnerable, yet many Boston homes have windows with broken or non-existent locks. Some older windows have locks that appear functional but require only moderate force to defeat.
Common Window Vulnerabilities
During security assessments across Boston neighborhoods, we consistently identify these window security issues:
- Broken or missing window locks
- Windows that can be lifted even when "locked"
- Screens with no security features (easily removed from outside)
- Basement windows with no locks at all
- Air conditioning units that aren't properly secured
Comprehensive Window Protection
Effective window security involves multiple layers:
Lock Upgrades: Replace or repair all window locks. Modern window locks include:
- Keyed window locks for high-risk windows
- Sash locks that secure double-hung windows in closed positions
- Pin locks for sliding windows
- Ventilation locks that secure windows in slightly open positions for airflow
Physical Barriers: Consider adding:
- Security bars for basement and ground-floor windows (choose quick-release models for fire safety)
- Window security film that prevents glass from shattering
- Security screens with reinforced frames and mesh
Environmental Strategies: Strategic landscaping deters window entry. Thorny bushes beneath windows create natural barriers that make accessing windows difficult and noisy. Motion-activated lights near ground-floor windows eliminate the cover of darkness that burglars prefer.
Our team can assess your windows during a comprehensive security consultation and recommend solutions that balance security with your home's aesthetic and your budget.
Mistake #7: Neglecting Security System Integration
Many Boston homeowners have assembled their security piecemeal over the years: an alarm system from one provider, some security cameras from Amazon, smart locks from another source. While each component may work individually, they don't communicate with each other, creating a security system with blind spots and missed opportunities for comprehensive protection.
The Fragmented Security Problem
Disconnected security systems create several issues:
- Multiple apps to monitor different security aspects
- No centralized alerts when problems occur
- Inability to trigger one system based on another's alerts
- Gaps in coverage between different security zones
- No coordinated response when security is breached
Integrated Security Solutions
Modern home security works best when all components communicate seamlessly. Our surveillance and access control services help Boston homeowners create unified security ecosystems where:
- Cameras activate when locks are engaged or disengaged
- Smart locks automatically secure when alarm systems are armed
- Entry sensors trigger camera recording and lighting
- All alerts route to a single monitoring interface
- Automation creates the appearance of occupancy when you're away

Boston-Specific Security Considerations
Living in Boston presents unique security challenges that homeowners should address:
Seasonal Factors
New England weather impacts security. Winter months bring early darkness, giving burglars extended cover. Frozen locks can fail when you need them most. Summer vacation season sees increased break-in attempts. Our team helps Boston homeowners prepare their security systems for seasonal challenges, ensuring locks function in sub-zero temperatures and homes remain protected during vacation periods.
Urban Density Considerations
Boston's mix of single-family homes, multi-unit properties, and apartments creates varied security needs. Triple-deckers require securing multiple entry points and coordinating between tenants. Historic properties need security solutions that comply with preservation guidelines. Our experience across Boston neighborhoods means we understand the specific requirements of your property type.
Student and Rental Populations
Areas with high student or rental turnover need different security strategies. Master key systems allow property owners to maintain access while giving tenants individual keys. Electronic access control eliminates the need to rekey after every tenant change. We specialize in solutions for Boston's rental market, protecting both owner and tenant interests.
The Value of Professional Security Assessment
While this guide provides comprehensive information, every home has unique vulnerabilities based on layout, location, and existing security. A professional security assessment identifies your specific risks and prioritizes solutions.
What to Expect During an Assessment
Our comprehensive security evaluations include:
- Physical inspection of all entry points
- Lock functionality testing
- Vulnerability identification based on your neighborhood's crime patterns
- Prioritized recommendations based on risk and budget
- Competitive quotes for recommended improvements
Most importantly, you'll receive education about your home's security so you can make informed decisions. We believe homeowners should understand why we recommend certain solutions and how each component contributes to comprehensive protection.

Frequently Asked Questions
How much does it cost to rekey a house in Boston?
Rekeying costs vary based on the number of locks, but most Boston homes with 3-5 exterior locks spend between $150-$300 for complete rekeying service. This is significantly less expensive than replacing all locks and provides the same security benefit.
Should I rekey or replace my locks?
If your existing locks are in good condition and meet current security standards, rekeying is the cost-effective choice. Replace locks if they're damaged, outdated, or don't meet modern security requirements. Our technicians can assess your locks and recommend the best approach.
How quickly can a locksmith respond to an emergency in Boston?
Response times vary by location and time of day, but professional locksmiths typically arrive within 30-60 minutes for emergency calls. Our team serves the Greater Boston area with fast, reliable emergency response for lockouts and security concerns.
Are smart locks secure enough for Boston homes?
Modern smart locks from reputable manufacturers provide excellent security when properly installed. They offer advantages over traditional locks, including access logging, temporary codes, and remote control. Choose smart locks with backup key access and ensure they're installed by professionals who configure them correctly.
What's the best lock for a Boston apartment door?
Apartment dwellers should install Grade 1 deadbolts with at least a one-inch throw. If your landlord permits, add a door reinforcement kit. For additional security, consider a portable door lock or security bar that you can remove when moving.
How often should I update my home security?
Review your security annually and after any of these events: moving to a new home, ending relationships with service providers who had keys, experiencing attempted break-ins, or when locks show signs of wear. Technology advances rapidly—locks and security systems from more than 10 years ago may need upgrading.
