Locks are essential to the security of your home or office. They require a matching key or code and may require an experienced locksmith to install. Different styles are available and each provides a specific level of safety. Knowing how they work could determine the best option for the property, so take a closer look at the following to become familiar with the basics.

How Do Locks Work?

Most locks work by using a series of pins or tumblers inside the lock cylinder that must be aligned in a certain way for the lock to turn. When you insert the correct key, the pins or tumblers are lifted to the correct height, allowing the lock to turn and the door to be opened.

Some use combination codes or electronic keypads instead of physical keys. Others use different types of locking mechanisms altogether, such as deadbolts or padlocks. But regardless of the specific type of lock you’re using, the basic principle remains the same: the lock must be “unlocked” in some way for the door to be opened.

What Are the Different Types?

Perhaps the most common type of lock used in residential settings, deadbolts are typically installed on exterior doors. They are usually operated by a key from the outside, and a thumb turn on the inside. Deadbolts come in a variety of sizes and styles and can be either single-cylinder or double-cylinder.

Padlocks are a type of lock that are not permanently attached to any one object. Instead, they can be used to secure everything from toolboxes to storage units to bicycles. Padlocks come in a variety of sizes and styles and can be either keyed- or combination-based.

Electronic locks are becoming increasingly popular in both residential and commercial settings. They can be operated using a keypad, a fingerprint scanner, or even a smartphone app. Electronic locks are typically more expensive than traditional locks, but they offer a high level of convenience and security.

Smart locks are a type of electronic lock that can be controlled remotely using a smartphone or other device. They can be programmed to unlock automatically when you approach the door, or to only allow access to certain users at certain times. Smart locks are typically more expensive than other types of locks, but they offer a high level of convenience and security.
