A Guide to Different Types of Door Knobs & Locks Explained

When it comes to door hardware, there are various types of door knobs and locks available to suit different styles, security needs, and functionality. Here are some common types:

1. Door Knobs

– Passage Knobs: These knobs are used on interior doors and do not have a lock or latch mechanism. They are typically used for closets, hallways, or other areas where privacy or security is not required.
– Privacy Knobs: Privacy knobs have a locking mechanism and are commonly used on bedroom or bathroom doors. They feature a push-button or twist lock on the inside and can be unlocked from the outside with a small tool in case of emergency.
– Dummy Knobs: Dummy knobs are non-functional and are typically used for decorative purposes or to create a symmetrical appearance on double doors. They do not have a latch or lock and are surface-mounted.

2. Door Locks

– Deadbolts: Deadbolts are popular for their high level of security. They have a solid metal bolt that extends into the door jamb and offers resistance against forced entry. Deadbolts can be single-cylinder, operated with a key from the outside and a thumbturn from the inside, or double-cylinder, requiring a key for both sides.
– Lever Handle Locks: Lever handle locks are commonly used in commercial settings but are also gaining popularity in residential applications. They offer easy operation and can be ADA compliant for accessibility. Lever handle locks may have a key cylinder or push-button locking mechanism.
– Keypad or Electronic Locks: These locks use a keypad or electronic access system for entry, eliminating the need for keys. They can be programmed with unique codes or integrated with other security systems. Some models may also offer biometric authentication, such as fingerprint scanning.
– Smart Locks: Smart locks are connected to a home automation system and can be controlled remotely using a smartphone or voice commands. They offer features like keyless entry, remote access, activity monitoring, and integration with other smart devices.

It’s important to choose door knobs and locks that meet your specific needs, including security requirements, aesthetic preferences, and compatibility with the door and its surrounding hardware. Consider consulting with a locksmith or hardware specialist for guidance and to ensure proper installation and functionality.
