Douglas County police data consistently identifies the same pattern: garage walk-through door is the #1 entry point for residential burglary in Highlands Ranch. Not the front door. Not a window. The unassuming side door homeowners forget to lock. Here's why it happens and the simple upgrade that defeats it.

The Pattern Burglars Use in Highlands Ranch

Step-by-step, the typical Highlands Ranch garage burglary:

Burglar checks the overhead garage door. If it's open (and ~5% of Highlands Ranch homes leave it open at night), they walk straight in.
If the overhead is closed, they check the side walk-through door. About 30% are unlocked because homeowners assume the closed garage door is enough.
Once inside the garage, they try the interior door to the home (the "mudroom" door). About 60% of these are unlocked.
If the mudroom door IS locked, it's usually a builder-grade Kwikset deadbolt. A bump key or pry bar opens it in under 60 seconds without making noise.

Total time from approach to inside the home: 90 seconds. No broken windows, no kicked doors, no neighbors hearing anything.

Why the Garage Is Such a Soft Target

Habit blindness. Homeowners associate "garage closed" with "house secure" and forget the side door entirely. We've serviced calls where the side door wasn't locked for weeks.

Low quality default hardware. Builder-grade locks on garage side doors are typically the cheapest option in the build. ANSI Grade 3 residential locks. Vulnerable to bumping, picking, and forcing.

Hidden from street view. The garage side door is usually not visible from the street — tucked behind a fence or against a side yard. Burglars work undisturbed.

Mudroom backup is weak. Most Highlands Ranch homes have a builder-grade deadbolt on the interior garage-to-home door. Same vulnerabilities.

The $585 Fix That Defeats This Entirely

Two upgrades, total typical cost $585:

1. Smart Lock with Auto-Lock on the Garage Side Door ($285-$485)

Yale Assure or Schlage Encode with the auto-lock feature enabled. The door locks automatically 30 seconds after you close it. Even if you forget, the door locks itself. Combined with a keypad code so you don't need to fish for keys when entering from the driveway.

2. High-Security Deadbolt on the Interior Mudroom Door ($285-$520)

Replace the builder-grade Kwikset deadbolt with a Medeco M3, Mul-T-Lock MT5+, or Schlage Primus. These resist bumping, picking, and drilling for 5+ minutes. Most burglars give up and leave once they hit one.

Highlands Ranch Neighborhoods Most Affected

Per public Douglas County crime maps:

Eastridge and Westridge — older subdivisions, many original-builder hardware still installed. Highest garage entry burglary rates.
Northridge — similar profile, garage-attached homes from 1985-1995 builds.
Verona and Highland Walk — newer townhomes with shared HOA-managed garages; communal entry creates extra exposure.
BackCountry and Sterling Ranch — lower rates because newer hardware is generally better, but premium home values make them targeted when the lock fails.
