I am having a difficult time trying to remove an old door knob. After removing four screws is still does not budge. Ive tried to go at it with pliers but still cant get the thing off. Here are some pictures,
Front knob, I tried to remove the metal plate where there appears to be a hole underneath. Im not sure what this hole is for.
Rear of the knob where i removed the two screws.
Side plate where i removed two screws.
I removed a cap the door knob had and this is what it looked like inside.
