Style of Doorknob

A doorknobs appearance is often the deciding factor as homeowners want it to match with a room's overall theme or decor. A simple round knob of a solid color might fit into some environments, while a lever handle with a burnished metal look may be more appropriate for others. The door plate around the handle can also add sculptured layers to the door's appearance while providing protection to the surface surrounding the handle.

Security Options

When it comes to security, there are three main types of doorknobs:

No lock. The simplest design has no locking capabilities at all and offers no added protection.
Simple keyless lock. This design has a lock that can be operated from one side of the door, preventing others from getting through. These are commonly used on bathrooms or bedrooms. In case of emergency, there is usually a small hole or indentation in the knob on the other side allowing access with a small tool if needed.
Key lock. This is the most secure option for a doorknob. One side has a simple mechanism to operate the lock, and the other side can be unlocked with the unique key provided with the doorknob. A locksmith can usually rekey this type of door lock if the original key is lost or compromised.

Fit The Door Pattern

The new doorknob must also match the pattern of holes in the door. The diameter of the hole, the length of the plunger and the thickness of the door must all be taken into consideration to ensure that the knob fits properly.
