3 Common Types of Door Lock

December 23, 2021

A door lock is a very important part of your home security system. A good door lock provides peace of mind in knowing your home is protected. When installing a door, you will find many door lock options. In this article, we will be explaining some of the most common types of door locks to help you pick the right one. 

Doorknob Locks

Although knob locks are very popular, they do not provide a lot of security, especially when used on the front door and this is why they are often paired with a deadbolt. The locking mechanisms are located inside the knobs themselves. The doors have cylinders (the part where the keys go in) on one or two of the knobs depending on whether you want the door to open from the inside or not. Because malicious persons can break into them with simple tools like a hammer, they are no longer popular outside doors.

Deadbolt Locks

A deadbolt is a simple mechanism where you have to move the lock yourself. A deadbolt does not rely on a spring, and this is why you will see it used in lots of doors. There are also locks that use a key that turns the deadbolt to lock it in place.

There are single- and double-cylinder deadbolt door locks. The single locks are opened or closed from one side, while you can open the double cylinder locks from both sides.

Handle set locks and modern deadbolt locks are just two examples of door locks that use deadbolts.

Biometric and Electronic Locks

Electronic and biometric locks have become very popular over the last few years as more people have started taking home security seriously. Electronic locks are door locks that do not require a key to open. The most common types of electronic locks are biometric locks, keypad locks, and card locks.

Keypad electronic locks require a special code to be entered before the door is opened. Card electronic locks require a card for entry, and you will find many of these in hotels and motels.

Biometric locks are electronic locks, but they incorporate biometric authentication so that only authorized persons can assess the house. This can be the face, a fingerprint, or a combination of both plus a special code. 

The main reasons for getting electronic locks are security and peace of mind. To ensure both, homeowners should get in touch with locksmiths who are experienced in installing electronic locks correctly.

Door locks range from very simple designs to more complicated designs like electronic and biometric doors. They all offer differing complexity and security, which means they are meant to be used on different doors. When choosing a lock, choose one that provides at least the minimum level of security you need and one suited for either interior or exterior doors.
