Two main categories of locks exist: indoor and outdoor. Indoor locks secure rooms and hallways, while outdoor locks protect pathways leading to and from the exterior of the home. Interior locks don’t usually need as much technology or security as outdoor ones, for their sole purpose is privacy. Outdoor locks tend to be more heavy-duty, because they secure entry ways into the home.
Both types come in a variety of colors, and materials making it easy to combine aesthetic appeal with home security.
Here are some of the most common forms of locks
This type doesn’t lock and is merely a means to keep a door closed or open. This is the most common and one of the most inexpensive types of indoor locksets.
This one locks only from one side, typically the inside of the room. It is ideal for bedrooms or offices in which you want privacy, and usually comes standard in all bathrooms of the home.
The dummy knob is solely for decoration purpose; it does not lock or have a latch. Simply pull to open. This should only be used within the house or perhaps an outdoor shed that does not need to be locked up.
This one can be locked from the outside of the door as well as the inside. The manner in which it opens and closes varies. The outside is usually accessible only by key, while the inside can range: from a push-button to a turn button, to another key hole.
The Deadbolt Lock
The deadbolt lock is great for doors that need top security. Most deadbolt locks are installed on the front door. When closed, a “bolt” (the standard is one inch long) enters inside the frame of the doorway, making for a solid close of the door. Thieves cannot pry this open because there is no spring attached and the only way they could open it, without a key, is by breaking the door frame.
A flat, rectangular box fits inside a pocket in the door. There is usually a deadbolt and a latch bolt. The knob is commonly connected to the deadbolt of the door. This one is probably among the most expensive and is recommended to be installed by a locksmith.
Keyless Entry System
A combination of deadbolts and latch systems can be used. No key is needed. Biometric fingerprinting, remote controls, and digital keypads are used to replace the function of the key. To see more on this, read our article on Keyless Home Entry.
This is a lock that combines a handle (for easy opening) with typically, a type of deadbolt door. It can either be one complete unit, or be divided into two parts, with the handle detached from the keyhole or knob.
