The doorknob on my master BR closet is broken... the knob will turn but nothing happens. The door opens into the closet, so I cannot access the screws or the door hinges on the inside of the closet. The molding on the bedroom side of the door prevents me from sliding a credit card to move the latch. The knob has no lock, just a flat surface on the knob, but other bedroom doorknobs have a small access hole in middle of the knob to insert a small screwdriver or tool to open it from the outside. This knob does not, so I tapped a small hole in it & inserted a screwdriver - I can turn the mechanism inside but it won't free the latch. Tried WD40, but it didn't help either. There is also no release hole on the shaft side of the door knob to press to remove the knob. At this point the only option I can see is to use a hacksaw to remove the door knob so I can access the hole and try to remove the parts with needle nosed pliers. I don't want to remove the molding either. Any other suggestions? Thanks!
