Mechanical Keys: The Classics That Still Rule the World
House Keys
House keys are arguably the most common type of key we interact with daily. types of keys These keys are typically cut in a specific pattern to match the pins in a door lock cylinder. When the key is inserted, the pins align to allow the lock to turn.
The design may seem simple, but there’s a lot going on inside. House keys are usually made of brass or nickel-plated brass for durability. They can be duplicated easily, which is both convenient and potentially risky if they fall into the wrong hands.
In recent years, high-security house keys have become more popular. These keys have complex patterns and are harder to duplicate. Some even require a special authorization card to make copies.
Car Keys
Car keys have evolved significantly over the years. Originally, types of keys they were just simple mechanical keys used to unlock doors and start the ignition. Today, many car keys are transponder keys or key fobs with electronic components.

Padlock Keys
Padlock keys are small, sturdy, and usually designed to be carried on a keychain. These are typically used for lockers, storage units, gates, and bicycles. types of keys The design of the padlock key depends on the lock mechanism—some use pin tumblers, others use warded designs.
Warded padlocks are easier to pick and are generally considered less secure. In contrast, pin tumbler padlocks offer better security and are more common today.
Padlock keys are a favorite for people who want to secure items on the go. They’re easy to use, widely available, and versatile.
High-Security Keys: Because Some Things Need Extra Protection
Dimple Keys
Dimple keys are designed with dimples (small holes) on the flat side of the blade, rather than the traditional teeth-like cuts. These keys work with dimple locks, which are known for their increased security.

Abloy Keys
Abloy keys are part of a disc tumbler lock system developed in Finland. types of keys These keys are flat and have cuts on the edge that correspond to rotating discs inside the lock.
The design makes them resistant to picking, drilling, and other forced entry techniques. Abloy locks are often used in government buildings, critical infrastructure, and high-end commercial properties.

Fobs are popular in modern workplaces, apartments, and cars. They offer a convenient way to unlock doors without inserting anything. Some even offer multi-functional features like panic buttons or remote start.
However, key fobs rely on battery power and can stop working if the battery dies. They also pose security risks if lost or cloned.
Mobile Keys
Mobile keys are the latest innovation in key technology. types of keys These are digital keys stored on your smartphone, allowing you to unlock doors with an app or a tap.
Hotels, smart homes, and workplaces are increasingly adopting mobile keys. They’re convenient, customizable, and eliminate the need to carry physical keys.
