If you don’t see any exposed screws, don’t get frustrated! You’ll most likely have to depress or unscrew some type of recessed fastener in the handle’s neck.
If you plan on reinstalling the door mechanism, store the screws in a safe spot to avoid misplacing them.
The latch is the bolt that fits into the strike plate on the door frame and keeps the door closed.
The paperclip or tool will spring the door mechanism, allowing you to pull out the handles.
You should be able to pull off the handles after removing the recessed screw. If the spindle that connects the handles doesn’t come out, you might have to pry off or unscrew the cover plate behind the handle in order to access mounting screws.
If you don’t have an Allen wrench, purchase a fold-up pocket set with variously sized Allen wrenches at a hardware or home improvement store.
The cover plate behind the door knob or lever may be round or rectangular, depending on the handle’s design. After prying off the cover plate, you should see screws that hold the inner mechanism together.
For some designs, there’s a visible slot that releases the outer handle as well as screws behind the cover plate that hold the inner mechanism together.
