Parker doorknobs that use center spindles sometimes become difficult to turn. Occasionally, the doorknob gets hit and slightly bends the spindle inside. When this happens, it is necessary to remove the Parker doorknob plate spindle rod and either straighten the spindle rod or replace it with a new one. Removing the Parker doorknob is much simpler than many other brands because there is no mounting plate securing the outside doorknob to the door.
Things You'll Need
Open the door so you are able to access both sides of the Parker doorknob. This also prevents accidentally locking yourself in the room while working on the doorknob.
Find the set screw on the neck of the inside doorknob. The screw is most likely pointing toward the hinge side of the door. This position is to keep the screw unseen during normal operation.
Loosen the screw with a flat-head screwdriver. It is not necessary to remove the set screw; loosen it only two to three complete revolutions.
Grab the outside doorknob with one hand, and grab the inside doorknob with your other hand. Pull the inside doorknob away from the spindle. Once the inside doorknob is off, pull the outside doorknob out of the door.
Remove the C-clip on the back of the outside doorknob with a pair of needle-nose pliers. Grab the spindle with a pair of pliers while holding the doorknob. Pull the spindle out of the knob, twisting left to right as necessary. Some Parker doorknobs do not have the C-clip. The spindle unscrews from the back of the doorknob.
