Perhaps the most vulnerable, yet overlooked, entrance to a home is the garage door. Not only do garages house some of our most valuable possessions but they also generally allow for direct entry into the house. Even if the passage door from the garage to the home is secured, by simply closing the garage door behind the, an intruder can use the door to shield their unlawful activity. Not to mention, they will often have access to the homeowner's very own tools to gain access into the residence. Perhaps you're beginning to recognize the value of properly securing the garage. It is a misconception that having an electronic garage door opener (GDO) provides adequate security. Experienced intruders seeking entry will have minimal difficulty bypassing an automatic garage door. Carelessness lead to many uncontested home invasions through the garage. Some examples would include: forgetting to close your garage door, leaving your remote control in your car, not locking the passage door or sharing the keypad combination with too many non-essential parties. Needless to say, if the home is not equipped with an automatic GDO, it is imperative to employ a solid mechanical locking mechanism.
