# How to Fix a Push Button Door Knob That Won't Lock
Push-button door knobs are used throughout the home as a cheap way to lock interior doors. The lock on a push-button knob is meant strictly for household privacy. Often they stick or break due to excessive pressure being placed on the door. When a push-button door knob begins to fail it either needs greasing or complete replacement to fix. No worries; a new doorknob can run you as little as $20 and the installation takes less than an hour.
