Importance of Dead Bolt Locks

One of the important type of home security lock is Door locks. They go farther to protect your home than a simple ordinary type of lock would. If you plan to upgrade your locks, it will greatly enhance the security of your home. Most door locks can be opened by taking the pressure off the spring, but to open a dead-bolt a burglar would have to tear the whole lock out and it takes time and more work.

Let me tell about the mechanism of dead bolt, It t is a home security door lock that has a piece of steel, called a throw, which protrudes from the lock, goes through the door, and embeds itself at least an inch into the doorjamb. When you have a deadbolt you need to cycle the cylinder before the throw will withdraw from the doorjamb so that you'll be able to open the door. Because of these qualities, deadbolts are much harder to pick and make forced entry extremely difficult.

There are several types of dead-bolts used with a front door lock. It can have a vertical design that better protects the door from being forced open. Also, there are two cylinder dead-bolts. With these styles, two keys have to be locked at the same time. The best protection is the double lock.

Even if you live in a safe neighborhood, you should still install a deadbolt lock. The low cost of the lock will give you a sense of security and is well worth the small prices. A good lock can stop thieves from breaking into your home. Consider installing them, even if you think you don't need them. It is a small effort to protect your home.

If you don't already have a dead-bolt on your door, installing one can be labor-intensive. Drilling holes in the jamb as well as the door are required to ensure that the lock fits properly. Usually, this type of lock is placed above the doorknob. A different kind is installed only on the interior side of the door that is used when the resident is inside the home. No matter what type of lock you install, you will save money and be better protected with a home security door lock.

Locks, Bolts and Keys For Your Home

Most security experts agree that a single outer door lock will not provide adequate protection. For example, any tumbler-type lock with an opening for a key also provides an opening large enough for the lock to be picked. Thus, a combination of two different types of locks are recommended. Here are the most common types of locks used in the home:

Spring Latch Locks: A popular and convenient lock that snaps closed whenever the beveled latch seats into a striker plate is the spring-latch lock. However, this lock can be easily forced by inserting through the door frame a thin blade or stiff plastic between the latch and the strike plate. Thus, a spring lock should always be augmented by a second lock of a different type.

Dead Bolt Locks: The dead bolt lock features a solid, rectangular latch that forms a bolt between the door frame and the door itself. This lock is difficult to force or jimmy and is a good choice as an auxiliary to any other key lock. It's available for either key operation or manual interior knob.

Barrel-Type Bolt: A barrel-type bolt serves the same function as the dead-bolt lock but is restricted to manual, interior operation only. It may be used with an inxpensive night-latch, and it is difficult to force if it's well made and installed properly.

Chain Locks: Used as a supplementary interior lock, the welded chain offers a valuable security feature. It permits the user to open a door partially to exchange letters, messages, or small parcels without completely unlocking the door. For proper mounting, the slide should be installed just above and slanting toward the chain.

Remember, if you have taken possession of a new home or apartment, you should immediately change the pin-tumbler locks on all exterior doors. A registered locksmith can usually alter the previous combination.

Self Defense at Your Residence - Install Dead-Bolt Locks on All Doors For Home Self Defense

Installing dead-bolt locks on all the doors of your residence is an additional line of home safety and self defense. It used to be that locks were only on door handles and people only locked the doors when they went to bed. Many did not even lock the doors if they left the residence for a short period of time. Children did not carry keys and could get in the house after walking home from school (by themselves!) Times have changed.

Now most people keep their doors and windows locked at all times. Dead-bolt locks have become the number one way of locking doors. Installing two or three dead-bolts per door is not uncommon. Although it is not impossible to kick a door open, like in the old movies, it is much more difficult with dead-bolts. The reason is, the dead-bolt, when engaged moves a one inch or longer solid piece of metal bar into the door frame. Trying to kick in a door now requires breaking a large portion of the door frame.

There are different types of dead-bolt locks. Some are keyed and some are just locked from the inside. You can purchase a kit of two or more locking doorknobs and dead-bolts which use the same key. That way you can replace the existing doorknobs an all doors with new door locks and dead-bolts and have fewer keys to carry.

If you want a little more peace of mind and a first line of self defense for your residence install a number of dead-bolts on your doors. You never know when you may need some extra protection. And if you live in a windy area additional dead-bolts can keep the wind from blowing the doors open.

Locks and Bolts For External Doors

Bolts can be used to provide extra security on external doors fit one to both top and bottom of the door. Barrel, padbolts and tower bolts can be screwed to the sur¬face of a door. Each has a long bolt which is generally shot into a staple (a hoop of metal) fixed to the door frame. Always choose a bolt with a heavy-duty staple and long fixing screws. Alternatively, the bolt may be shot into the sill or floor or into the door frame.

The bolts are neither key-operated nor deadlocking and so may be easily undone if access is possible. If you want to use one near glass, chose a padbolt - these can be secured by a padlock.

Flush bolts work in a similar way to tower and barrel bolts - in that they shoot a bolt into the frame and are non-locking - but they are designed to be mortised into the edge or face of the door. This makes them particularly suitable for double doors or where a concealed fitting is required.

Locking bolts

You can get key-operated bolts which fit on the face of a door, but the better choice for a normal door is a mortise rack bolt.

For double doors which open out¬wards, fitting a mortise rack boll can be difficult and there is a special type of locking bolt which is fitted to the inner surface of the door and shoots a bolt up into a staple fitted to the underside of the top of the door frame. The lock is pushed to close: a key is needed to open it.

Because these locks are operated from the inside, they do not have as many key differs as external door locks.

Mortise rack bolts

These can be mortised into the edge of a wooden door and should be fitted so that the key is on the inside face. They are inconspicuous when fitted and will resist some forcing. The deadbolt is operated by a key and enters a striking plate mortised into the door frame. Each model usually has one universal key only. Some mortise rack bolts can be unlocked without a key these should not be used next to glass.

You should fit mortise rack bolls to both the top and the bottom of a door: on French windows, fit four not just two on the closing leaf. To do this you have to cut a mortise in the edge of a door in a similar manner to that described for Fit¬ting a mortise deadlock -but in this case the hole for the key should not be drilled right through the door.

Padlocks

These can be used with a hasp and staple (together often called a padlock bar) to lock garden sheds, garages and so on. The hasp is fitted to the door or gate and the staple to the frame. The padlock locks the two together. Choose a heavy-duty hasp and staple with fixing screws which are concealed when the padlock is in place. Use a closeshackle padlock which has the hoop (shackle) close to the body of the lock.

Other security devices for doors

Hinge bolts (sometimes called dog bolts). These provide protection against forcing (or even removal) of a wooden door from the hinge side, particularly doors which open outwards. The bolt enters the striking plate when the door is closed. They should be fitted to the top and the bottom of a door, close to the hinges. The bolt is usually mortised into the hinge edge of the door, but it may be surface mounted. The striking plate is rebated into the frame in a similar way to a mortise lock.

Door chains

These prevent a door being opened more than a small amount (the chain is about 200mm long). A door limiter serves a similar function, but neither will provide more than limited protection, especially when the door is partly open. For full protection, a locking door bar is needed.

When fitting a door chain, position it close to the centre of the door and close to the edge to prevent marking the door when it is opened. The actual fixing is simple the chain receiving plate should be screwed to the door and the chain holding plate to the frame.

Door viewers

These allow you to see out¬side the door without opening it. Different models have different angles of vision - normally between 150 and 175 degrees. Choose one with as wide an angle as possible. Some models are made to fit different door thicknesses.

A door viewer should be fitted centrally in the door at eye-level and should be used in conjunction with a porch light.

The correct drill size is very important for secure fitting. You would also be interested in learning how to remove a window frame. Also learn how to add a garden window if you find some extra time to work on your home decoration.
