Theft and burglary in the Door Locking home are on the rise. According to statistics, every 13 seconds, a house break-in occurs in the United States. Break-ins and burglaries are more likely in homes without effective security equipment.

As a result, every homeowner should invest in a good security system to safeguard their home and family. Investing in a good door lock is one way to do this.

Not only for external doors, but also for internal doors, door locks are necessary. For instance, personal privacy is protected by restroom doors, and private information is protected by access to workplace doors.

You should consider not just security and burglar prevention when choosing a new lock for your door but also fire prevention and accessibility.

Door locks and their features

Imagine you’re having a new exterior or door installed and want to make sure you’re receiving the best lock for your money. Perhaps, you should look into the many types of door locks available.

This simple list includes the most popular types of door locks available now around the world, allowing you to make safe and informed decisions about your property’s security.

  • Padlocks
  • Deadbolt locks
  • Cylinder locks
  • Lever handle locks
  • Chain locks
  • Smart locks
  • Electronic locks


These locks can easily fit to an entrance gate, door or a fence to prevent theft or theft.

These locks come in a variety of shapes and sizes, with little padlocks used to secure personal journals and larger, more durable padlocks used to secure warehouses and industrial facilities.

There are two main styles in padlocks:


Combination padlocks contain dials that can be spun to reveal some digits or letters. This will release and the lock can unlock after these line up in the correct combination.


When you insert a key into a keyed padlock, it spins to release the lock. Some keyed padlocks are key-retaining, meaning you cannot remove the key while the padlock is open.

Deadbolt locks

External doors with deadbolt locks are prevalent because they provide a high level of security against invaders. They work with a key entered into a cylinder, and the lock can only be unlocked by turning the key.

There are multiple styles of deadbolt locks available. Such as:


Only one side of the door, the exterior side, can lock using single cylinder deadbolt locks. They can unlock without a key on the inside of the door.


Double cylinder deadbolts feature two cylinders that operate with a key from both the inside and outside of the door.

Thumb turn

It can function as both a single-cylinder and a double cylinder deadbolt, a lockable thumb-turn deadbolt is a hybrid of the two.


This type of lock is ground fixed; it is popular as an additional layer of security on external doors because it requires minimal installation.

 Cylinder locks

Cylinder locks are known to be among the safest door locks available, though not all are made equal, so check the protection rating before purchasing.

For glass entryway doors and business doors, cylinder locks are commonly used as glass door locks. Following are some types of locks:

Rim locks

A pair of screws on the inside of the lock screw into the back of the cylinder, securing the rim lock in place. These locks feature a lengthy piece of metal that extends out the back of the lock and installs on the inside of the door.

Mortise locks

Rather than being mounted on the door’s surface, they are put within it. The lock bolts onto the mortice hardware, which is located within the door.

Euro profile cylinder

They’re popular since they’re simple to use and provide a high level of security. They are available in a variety of configurations, including single and double cylinders.

Lever handle locks

You can find these types of locks in commercial buildings. However, you might see them on hospitals or office doors as well.

These look similar to regular lever door handles. However, they have an additional feature of a keyhole so that the door can lock for privacy or security.

They’re preferable to locking door handles with knobs because they’re easy to grab and function with just a slight push-down motion.

Chain locks

The chain of the lock attaches to the door, whilst the catch attaches to the door frame. Simply slide the chain through the catch to secure the door.

This design allows a user to open a door a few inches to see who is outside without completely unlocking it and letting an outsider enter their home.

Smart locks

Smart locks are a new form of door lock that is quickly gaining popularity and changing how people think about home security. They enable the user to use their smartphone as a key, allowing them to open it from anywhere on the planet.

If you reside in a remote place with spotty Wi-Fi, a smart lock may be inconvenient and more trouble than it’s worth. Wi-Fi-enabled smart locks consume batteries as well, and the Wi-Fi drains them quickly.

Electronic locks

Electronic locks typically operate by entering a code on a computer screen or by using a keycard. These keyless locks are widespread in hotel rooms and businesses.

They are also becoming more common in apartment complexes and private homes. Most electric locks run by batteries, allowing you to gain access to your house or workplace even if there is a power outage.


 To conclude, there are many different types of door locks to pick from for your home or company, and it can be difficult to figure out which one is best.

There are various types of door locking mechanisms that fit into the profile of any homeowner or company owner, depending on their demands and desired level of protection.

Perhaps, whether you need a lock system for a semi automatic door system or your home doors, a proper lock is essential.

Therefore, you should invest in a good security system to protect your office or home.
