Here’s a look at 10 types of door knobs that are out there, for you to familiarise yourself with them and make an informed purchase decision.

  1. Dummy knob

First on the list is the dummy door knob, designed simply for style and to enhance the design of the door. It doesn’t have a latching mechanism, and neither does it turn. It’s fixed, helping you push or pull the door.


  1. Lever handles

This door knob is also for opening and closing the door. It’s different from conventional round knobs in that, instead of grasping and turning, you just have to grab, then pull or push. This door knob is particularly beneficial to persons with arthritis, since you won’t keep twisting your wrist.

  1. Passage lockset

This one is designed for places where privacy is not an issue- like in your hallway or closet at home. It has 2 non-locking door knobs at either side of the door. It’s also ideal for children playrooms and bathrooms as they won’t be able to accidentally lock themselves in.

  1. Privacy lockset

Like its name suggests, this door knob is designed mainly for privacy purposes in interior doors (like to your bedroom). It has an interior lockset. The locking device is on the inside knob, and there’s no key device on the exterior. In case of an emergency you can insert a narrow object through the small hole from the outside, and depress or turn the locking mechanism to get it open.

  1. Entry lockset

This one has two door knobs, which you can lock either from the outside, or inside of the building/room. It comes in different designs, and is geared towards providing security and privacy. These door knobs come with a dead latch, and are popularly used for entrance doors. There are those that you turn or press a small button from the inside to lock, which you’ll need a key to open from the outside. Others operate with keys for both the inside and outside. In some cases, you can only use the inside knob to lock or unlock both sides.

  1. Deadbolt lock

This door knob is mainly for security. It doesn’t have any spring system to operate the bolt. You can only manually open it using a key, or turning the knob from the inside. The door is locked to the frame using the bolt mechanism, preventing the door from being pried open. The door knobs come in different standards, to fit into specific hole sizes and backsets. You can get them in either a single or a double cylinder deadbolt. The single operates using a key on the outside, and a turn button in the interior. The double cylinder uses key-access for both interior and exterior.

  1. Surface-mounted deadbolt

You won’t be making any holes in your door frame. The bolt of this door knob slides into a strike mounted on the surface. You can turn the bolt using the turn knob or your key.

  1. Night latch

This door knob locks automatically behind you when you close the door. It’s installed on the interior side of the door, and operates using a spring-loaded latch.

  1. Mortise lock

This door knob is on different kinds of doors, from apartment buildings to residential access-doors. It comes with a pin tumbler locking mechanism in its cylinder. You can operate the latch from either side of the door, except when the outside knob has been locked. You operate the deadbolt by turning the inside knob, while the deadbolt and latch bolt can both be operated using a key from the outside.

  1. Keypad knobs

These are for advanced security. They are used in commercial properties and government institutions for access to high-security rooms like vaults, and also in residential premises, like in garage entry doors and utility rooms. They can have audio and visual indicators that confirm activation of the lockset and some models even sound an alarm when the incorrect code is entered repeatedly. Some, especially for garage doors, can be operated via remote.
