Home Security Tips for Doors

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. After gaining access to your garage, burglars will look inside your car for keys and other valuables so it’s a good idea to 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 deadbolt 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.

• Use a solid core or metal door for all entrance points
• Use a quality, heavy-duty, deadbolt lock with a one-inch throw bolt
• Use a quality, heavy-duty, knob-in-lock set with a dead-latch mechanism
• Use a heavy-duty, four-screw, strike plate with 3-inch screws to penetrate into a wooden door frame
• Use a wide-angle 160° peephole mounted no higher than 58 inches

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 four-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 can sleep more safely in the future.

Sliding-Glass Patio Doors

Sliding glass doors are secured by latches not locks. They are vulnerable to being forced open from the outside because of these inherently defective latch mechanisms. This can be easily be prevented by inserting a wooden dowel or stick into the track thus preventing or limiting movement. Other blocking devices available are metal fold-down blocking devices called “charley bars” and various track-blockers that can be screwed down.

The blocking devices described above solve half the equation. Older sliding glass doors can be lifted up and off their track and thereby defeat the latch mechanism. To prevent lifting, you need to keep the door rollers in good condition and properly adjusted. You can also install anti-lift devices such as a pin that extends through both the sliding and fixed portion of the door. There are also numerous locking and blocking devices available in any good quality hardware store that will prevent a sliding door from being lifted or forced horizontally. Place highly visible decals on the glass door near the latch mechanism that indicates that an alarm system, or block watch/operation identification is in place. Burglars dislike alarm systems.

• Use a secondary blocking device on all sliding glass doors
• Keep the latch mechanism in good condition and properly adjusted
• Keep sliding door rollers in good condition and properly adjusted
• Use anti-lift devices such as through-the-door pins or upper track screws
• Use highly visible alarm decals
