Types Of Door Locks Explained: Secure Your Home With Confidence

In a world where safety is paramount, door locks play a pivotal role in protecting your home. Understanding the types of door locks available is essential for bolstering your home security. In this guide, we will explore various door lock options and help you make an informed choice.

Understanding Types of Door Lock Systems

Let’s talk about the stuff that makes door locks work. Before we dive into the types of door locks you might need, it’s helpful to know about the parts inside these locks. Understanding this hardware can help you choose the right lock for your needs.

1. Cylinders

A cylinder is the main part of a lock that you put your key into. Inside it, there are little pins that work like tiny springs. When you put your key in, it has a unique shape that pushes these pins up to a certain level. If you use the right key, it pushes the pins to just the right spots, and that makes the lock open up. This, in turn, lets the door unlock and open when you turn the key.

2. Bolts and Latches

To open or close a door, we use a special part inside the door called a bolt. This bolt is usually made of metal and it helps to keep the door and the frame together. Now, there are two types of door lock bolts:

2.1. Spring bolt: The spring bolt works a bit like a spring-loaded clip. When you push or pull the door, the spring inside the bolt helps it move to either lock or unlock the door. It’s kind of like how a click pen works.

2.2. Deadbolt: On the other hand, the deadbolt doesn’t use a spring. Instead, it uses a key or a knob on the door. You turn the key or knob to lock or unlock the door. Deadbolts are usually considered more secure compared to spring bolts because they are harder to force open.

3. Strike Plates

Imagine your lock is like a puzzle piece that fits into a square hole. This square hole is called a “box.” The strike plate is the other part of the puzzle, and it’s attached to the door frame. Its job is to guide the lock’s bolt into the box and keep your door securely closed.

Now, there are also fancy new locks in the market. These high-tech locks use smart technology to make sure your home is safe. They run on electricity and can be unlocked in different ways, like using a special code on a keypad or scanning your fingerprints or eyes. These advanced locks are all about keeping your place super secure!

1. Deadbolt Locks

Deadbolt locks are a classic choice for securing your entryways. Here are some of the different types of deadlocks you can choose from:

1.1 Single Cylinder Deadbolt: This type of deadbolt has a keyhole on one side and a thumb turn on the other. You use a key to lock and unlock it from the outside, while inside, you can simply turn the thumb to lock or unlock.

1.2 Double Cylinder Deadbolt: This deadbolt has keyholes on both sides, so you need a key to lock or unlock it from both the inside and the outside. It provides extra security but can be a safety concern as you need a key to exit, which may be difficult in emergencies.

1.3 Keyless Deadbolt: Keyless deadbolts use codes or electronic mechanisms, like a keypad or a smart lock, to lock and unlock without the need for physical keys. Some models may also have key backup options.

1.4 Jimmy-Proof Deadbolt: These types of door locks are surface-mounted on the door and frame, making it resistant to forced entry using tools like a crowbar. Lock and unlock it using a key or thumb turn like a single-cylinder deadbolt.

1.5 Vertical Deadbolt: Vertical deadbolts are mounted vertically on the door and frame, providing added security against forced entry. Operate them using a key or thumb turn, much like a single-cylinder deadbolt.

1.6 Rim Deadbolt: These deadbolts are installed on the inside surface of the door. They lock into a strike plate on the door frame. Turn a knob or thumb turn to lock and unlock it.

1.7 Mortise Deadbolt: Mortise deadbolts are installed within a pocket (mortise) in the door and require a key to lock and unlock.
