Depending on the mechanism used, a large number of door handles can be reversed. The door handles can be removed quickly and then shifted to another position as per your requirement. For instance - a door that opens towards you and has knobs on the right is the right-hand side door. To remove the handle, expose the screws, then remove them using the screwdriver. Choose pin holes on the lever body and then wrench these to dismantle the lever. Insert the spindle in the desired position, and then place the screws back in.
