Enhancing Security Beyond Your Front Door: A Guide for Four Square Mile, CO Homeowners


True home security means protecting every potential point of entry. Burglars often target less obvious entry points like back doors and garages. The team at Blackwood Mobile Locksmith helps Four Square Mile, CO homeowners identify and secure these vulnerabilities.

  • Sliding Glass & Patio Doors: Many standard factory latches on sliding glass doors are notoriously weak and can often be forced open with relative ease. Furthermore, these doors can sometimes be lifted off their tracks, creating another significant security flaw. To address these issues, we offer comprehensive solutions. We can perform sliding glass door lock repair on existing mechanisms or replace them entirely with more robust and secure models. We highly recommend adding secondary locking devices for any sliding door in Four Square Mile, CO; these include professional-grade charley bars (security bars), loop locks, or foot-operated bolts, all of which provide a strong physical barrier against forced entry. Additionally, we can install anti-lift devices that prevent the door from being dislodged from its track from the outside.
  • French Doors & Double Doors: The "passive" door in a set of French or double doors, which is the one without the main lock, is frequently secured only by weak top and bottom slide bolts. This makes it a vulnerable point of entry. Our solutions focus on reinforcing this weakness. We recommend installing a high-quality, single-cylinder deadbolt that extends securely into the passive door, effectively anchoring both doors. Alternatively, we can upgrade your system to a more secure multi-point locking system, which ensures both doors are firmly anchored to the frame at multiple points.
  • Garage Doors: The entry door from your garage into your Four Square Mile, CO house is a critical yet often overlooked vulnerability. Typically, this is an interior-grade door fitted with a simple knob lock, offering minimal security. If a burglar gains access to your garage, they then have a private, hidden space to work on getting into your main living area without being seen. To counter this, we strongly advise upgrading the entry door lock by installing a high-security deadbolt on the door leading from your garage into your house – you should treat it with the same level of security as any other primary exterior door. Beyond the entry door, we can also secure the garage door itself by adding manual slide locks to the interior of the garage door tracks. These provide a strong physical barrier, especially useful when you're home or away for extended periods.
  • Windows: Simple factory latches on windows offer very little resistance to being pried open, making them easy targets for intruders. While Blackwood Mobile Locksmith are not window specialists, we can provide expert advice on and install a variety of secondary window locks. These locks add a crucial layer of security, significantly bolstering the protection of your Four Square Mile, CO home, especially for ground-floor windows.By assessing every entry point, from your front door to your back patio, the professionals at Blackwood Mobile Locksmith can help you create a comprehensive security plan for your Four Square Mile, CO residence.Call us today for your affordable quote!

Four Square Mile is an unincorporated community and a census-designated place (CDP) located in and governed by Arapahoe County, Colorado, United States. The population was 22,872 at the 2020 census. The CDP is a part of the Denver–Aurora–Lakewood, CO Metropolitan Statistical Area. The CDP is surrounded by Denver on the north, west, and south and by Aurora on the east. The name is derived from the four square miles bounded by Quebec Street, Mississippi Avenue, Havana Street and Yale Avenue.

Denver’s annexations were ultimately stopped by the Poundstone Amendment; Aurora is not similarly limited but made its most recent annexation to Dayton Street in 1984, leaving nearly three of the four square miles unincorporated.
