Doors & Locks
Defending Your Home
The first step is to harden the target or make your home more difficult to enter. Remember, the burglar will simply bypass your home if it requires too much effort or requires more skill and tools than they possess. Most burglars enter via the front, back, or garage doors. Experienced burglars know that the garage door is usually the weakest point of entry followed by the back door. The garage and back doors also provide the most cover. Burglars know to look inside your car for keys and other valuables so keep it locked, even when parked inside your garage.
Use high quality Grade-1 or Grade-2 locks on exterior doors to resist twisting, prying, and lock-picking attempts. A quality dead bolt lock will have a beveled casing to inhibit the use of channel-lock pliers used to shear off lock cylinder pins. A quality door knob-in-lock set will have a 'dead latch' mechanism to prevent slipping the lock with a shim or credit card.
The Lock Strike Plate
The most common way used to force entry through a door with a wooden jamb is to simply kick it open. The weakest point is almost always the lock strike plate that holds the latch or lock bolt in place followed by a glass paneled door. The average door strike plate is secured only by the soft-wood doorjamb molding. These lightweight moldings are often tacked on to the door frame and can be torn away with a firm kick. Because of this construction flaw, it makes sense to upgrade to a 4-screw, heavy-duty, high security strike plate.
They are available in most quality hardware stores and home improvement centers and are definitely worth the extra expense. Install this heavy-duty strike plate using 3-inch wood screws to cut deep into the door frame stud. Use these longer screws in the knob lock strike plate as well and use at least one long screw in each door hinge. This one step alone will deter or prevent most through-the-door forced entries. You and your family will sleep safer in the future.
