Garage doors remain one of the most exploited entry points in home security—not because the door itself is weak,
but because most owners don’t know what vulnerabilities exist or how to fix them.

How Criminals Actually Break In: 5 Common Methods

1. Emergency Release Fishing

Thieves use a wire through the top seal to pull the emergency release cord.

Solution
Secure the release so it isn’t reachable from outside and improve the top seal.
If your door won’t close afterward, request service here:

3. Forced Side Door Entry

Many garages have a side door with a basic lock. Once inside, criminals can trigger the wall button.

Solution
Add a Grade 1/2 deadbolt, use a security bar, and install an alarm sensor on the side door.

4. Bottom Gap Exploitation

Worn weather seals create gaps large enough to see (and sometimes reach) inside.

Solution
Replace weather stripping, install a threshold seal, and ensure the door closes flush with no visible light.

5. Shared Garage Tailgating

In multi-unit buildings, criminals may follow residents through an open door.

Solution
Use timed auto-close, cameras at entry points, clear signage, and an access policy with building management.

NYC Urban Constraints & Solutions

Shared Driveways (Common in Queens/Brooklyn)

  • Use individual keypads per unit
  • Enable timed auto-close (45–60 seconds)
  • Add cameras covering shared entry zones
  • Establish an access policy with building management

Brownstones & Attached Homes

  • Coordinate alley lighting with neighbors
  • Secure side/rear access with Grade 1 deadbolts
  • Consider shared camera coverage for common access points

Co-op / Condo Rules

  • Review bylaws before adding cameras/alarms
  • Many buildings restrict exterior modifications
  • Work with the property manager on approved hardware lists
  • Smart opener upgrades are often allowed if appearance is unchanged

Mixed-Use Buildings

  • High foot traffic increases tailgating risk
  • Prefer keypads vs. remotes (remotes get lost)
  • Post signage: “Residents Only / Under Surveillance”
  • Coordinate access protocols with on-site security
