How to Fix a Pushbutton Doorknob


Internal mechanisms such as those found in doorknobs and locks need lubrication in order to perform their intended functions correctly. Lubricating sprays may be used effectively to clean a doorknob that has been dismantled; but, they do not give the lock with the long-term lubrication that it requires. As a consequence of this, the doorknob may get sticky, making it challenging to lock, unlock, or open the door. Instead, a tube of powdered graphite, which can be found at practically any store that sells key-making supplies, is the most effective lubricant for fixing a push-button doorknob.

  1. Savvy Security recommends using a screwdriver to loosen the screws that are securing the push-button doorknob to the door, and then pulling the front and back sections of the doorknob apart from one another.

  2. Loosen the two screws that are securing the door strike plate to the edge of the door, and then slide the door strike plate together with the bolt out of the hole in the door.

  3. Using a cloth, clean the bolt and connection rod that is attached to the handle. According to the instructions provided by Paul’s Travel Pictures, a little quantity of graphite powder should be applied to the bolt mechanism, and then the mechanism should be worked in and out until it glides smoothly.

  4. Install the bolt and strike plate again, and then make sure the two screws that are holding it to the door edge are adequately tightened. After positioning the inner handle over the rod and inserting the connector rod from the outer handle into the hole in the bolt mechanism, you should refrain from attaching the inner side of the handle at this point.

  5. Maintaining a firm grip on the door’s outer handle while turning it will allow you to check that the bolt is opening and closing as it should. Applying a little amount of graphite spray to the region where the rod passes through the bolt will help. Turn the handle from the outside so that the graphite may be worked into the mechanism. Continue doing this until the door bolt can be opened and closed without any difficulty.

  6. Install the inner doorknob, then use a screwdriver to put the mounting screws into place and tighten them. This will ensure that the knobs are securely attached to the door.

  7. After putting a key in the lock from the outside of the door, you should next put a very little quantity of graphite within the lock. You can lock and unlock the doorknob using both the key and the push-button and turning the inner doorknob to work the graphite into the lock and loosen the locking mechanism. You may accomplish this by alternating between these two methods. Use the cloth to remove any stray graphite powder that may have accumulated on the handles or the lock.

    Things You Will Need

    • Screwdriver

    • Rag

    • Powdered graphite


    Insert a tiny Allen wrench into the release hole and either push or spin the hex screw to remove the knob. Next, twist and take off the escutcheon to expose the mounting screws if your doorknob has an escutcheon that covers them.
