With time, door handles loosen as well as become difficult to convert and unlatch. Most entrance hardware made today purposes exposed screws, accessible on the “room side” of the particular door, to connect each halves of the take care of to each side from the door. But some existing brands (and most mature door hardware) use invisible chassis screws, a setup that requires that you take the doorknob as well as rose (cover plate) apart to tighten the screws.

The door hardware is fairly typical, but you could have something other than your button to release your knob. Also, some door roses unscrew in the chassis by hand (turn them counterclockwise) rather then snap onto it.
