Choosing Door Locks for Your Home: A Look at Latch-Based Locks

Choosing Door Locks for Your Home: A Look at Latch-Based Locks

It is advisable to trust the advice of a locksmith near you when it comes to which kind of locks you should have on your doors. However, it is critical to understand the pros and cons of each kind of lock in order to make an informed final decision to keep your home safe.

When it comes to door locks, and especially those you will use on your front door, you need to have a clear understanding of how each kind of lock will work. Latch-based locks are quite popular in most homes and are usually attached to a door handle or door knob. They are opened using a key from the outside and the door knob or handle on the inside. With these locks, you have two options: latchbolts and deadlatches, so here is a look at their working mechanisms to help you decide.

They also use a spring mechanism that allows the door to automatically lock itself once the door is shut. If you want a locksmith in Charlotte, NC, then you’ll need a reputable professional to handle the installation.

Latchbolt Locks

The latchbolts use the spring mechanism that facilitates the movement of the bolt. The spring is attached to the bolt and contracts and expands based on the movement of the door handle or in response to any pressure placed on the bolt. The bolt is designed in an angular shape and extends from the lock to the strike plate attached to the door frame with a corresponding space where the bolt fits in to effectively lock the door.

As you shut the door, the protruding blot will retract as it is pushed back by the strike plate until it reaches the hollow section where it will extend fully into it and secure the door. The latchbolt design is such that as you turn the door handle or door knob, the bolt moves in and out of the lock.

The advantage of a latchbolt is that the door will lock automatically and the only way to access the room is using a key from the outside or if you open it yourself from the inside. The disadvantage, however, is that it is quite easy to pick using a thin, flat tool like a card which can slide the bolt out of the hollow in the strike plate. Further, if a person gains access through a window, they only have to turn the door handle to let themselves out or other people in.

Deadlatch Locks

The other option for latches is the deadlatch. It functions in exactly the same way as the latchbolt only that it has an added feature called a guardbolt. This is a small bolt located beside the lock’s main bolt. Both bolts are attached to a spring within the locks such that they move together as you turn the door handle, much like with the latchbolt.

The difference is that although the latchbolt responds to pressure on the bolt by compressing the spring and retracting the bolt, the guardbolt on the deadlatch prevents the bolt from retracting when pressure is placed directly on it. This means that once the main bolt is in the strike plate, the guardbolt ensures that it remains in place until someone turns the door handle from the inside or opens the door with a key.

The advantage of this design is that, unlike with the latchbolt, one cannot use a flat tool to gain access into your home from the outside. It also locks automatically so that if you are running out of the house, you need not worry that you didn’t lock your door. However, it still has the disadvantages of allowing access from the inside since one doesn’t need a key for that. A burglar can break a window near your door and simply open up the door from inside.

With this information, you should be able to make the best choice for your home.
