Cape Cod's trusted local security experts since 2008 · Licensed & Insured
Cape Cod is one of the most beautiful places to live in New England — but it comes with unique security considerations that mainland homeowners rarely think about. Seasonal vacancy, heavy tourist traffic, and properties that sit empty for months at a time make Cape Cod homes attractive targets for opportunistic burglars.
In 16+ years of serving Barnstable County, our team at Bluefin Locksmith & Garage Door has seen every type of security failure. The good news: most break-ins are entirely preventable. Here are the 10 security improvements that make the biggest real-world difference.
Why Cape Cod Homes Are Uniquely Vulnerable
Unlike suburban neighborhoods with year-round residents watching each other's homes, many Cape Cod communities — especially in Chatham, Brewster, Truro, and Wellfleet — have neighborhoods that go quiet in the off-season. Burglars know this. They scout in summer and strike in the shoulder seasons when homes sit empty.
Additionally, vacation rental properties may have dozens of guests per year, each issued a key. That's a significant key-control problem that standard security practices don't address.
The 10 Tips
Most homes ship with Grade 3 builder-grade locks — the cheapest possible hardware. Upgrade to a Grade 1 deadbolt (ANSI/BHMA certified) on every exterior door. Look for brands like Schlage B60N or Medeco. A Grade 1 lock is 3x more resistant to forced entry. Cost: $60–$150 per lock installed professionally.
The deadbolt is only as strong as the frame it's mounted in. Standard strike plates use short ½" screws that fail with a single kick. Replace them with a heavy-duty strike plate secured with 3" screws that reach the stud. Door jamb reinforcement kits (like Door Armor) make kick-in attacks extremely difficult. This $30–$60 upgrade is one of the best security investments available.
This is non-negotiable. Previous owners, real estate agents, home inspectors, contractors, and neighbors may all have copies of your keys. Rekeying all exterior locks costs $150–$250 total and takes about an hour. It's the single most important security step for any new Cape Cod homeowner.
Sliding glass doors — common in Cape Cod homes — are notoriously easy to bypass. The standard latch is not a true lock. Add a secondary locking bar in the track and a pin lock through the frame. This two-minute fix prevents one of the most common entry methods.
Openers made before 1996 use fixed radio codes — a criminal with a cheap device can clone your signal and open your garage remotely. Modern openers use rolling-code technology that generates a new code with every button press. If your opener is old, it's time to replace it. Also, never leave your garage remote clipped to your car's visor — if your car is broken into, they have your home key.
If you rent through Airbnb or VRBO, a smart lock is essential. Generate unique time-limited codes for each guest — no key handoffs, no unreturned keys, no wondering who has access. You can lock and unlock from anywhere in the world via your phone. This is especially critical for seasonal Cape Cod rental properties in Falmouth, Hyannis, and Chatham.
The door connecting your garage to your home interior is often the weakest link in the entire house. Many are hollow-core doors with flimsy knob locks. Replace with a solid-core door and a proper Grade 1 deadbolt — treating it like a front door. This single upgrade eliminates a favorite entry path for burglars who access garages through overhead doors.
Darkness is a burglar's best friend. Motion-activated lights at all entry points — front door, side gates, garage, back patio — eliminate the cover of darkness. Solar-powered options are easy to install and especially useful for seasonal homes. Combine with a smart light timer for interior lights when you're away to simulate occupancy.
This sounds obvious but happens constantly. Posting "We're off to Florida for 3 weeks! 🌴" on Facebook tells every follower — including people you've forgotten you're connected to — that your Cape Cod home is sitting empty. Post vacation photos after you return.
Especially for seasonal residents who leave Cape Cod for the winter: have someone collect mail, park in the driveway occasionally, and check the property every 1–2 weeks. An active-looking property is the strongest deterrent of all.
Bonus: The 2-Minute Security Audit
Walk around your home right now and ask: Can I see inside from the street? Are any windows unlocked? Is my spare key under the mat or in a fake rock? (Burglars check these first.) Does my front door have a peephole? Is my garage door opener out of sight in my car? Fixing just these will put you ahead of 80% of homes on your block.

Frequently Asked Questions
What is the most common way burglars enter Cape Cod homes?
Over 34% of burglars enter through the front door, and 22% through a first-floor window. On Cape Cod, garage doors are also a significant vulnerability, especially homes with old fixed-code openers or unlocked interior garage doors.
Should I rekey locks when I buy a new home?
Absolutely. You have no way of knowing how many key copies exist. Rekeying all exterior locks is one of the smartest and most affordable investments for any new homeowner — typically $150–$250 for a whole home.
Are smart locks worth it for seasonal Cape Cod homes?
Yes, especially for vacation rentals. Smart locks let you manage access remotely, issue temporary codes to renters, and eliminate unreturned key risks — all from your phone no matter where you are.
