Door handles can be fixed by tightening the screws that hold the handle in place. If the screw is stripped, a new screw can be inserted with a drill. If the hole is stripped, a new hole can be drilled. If the door handle is broken, it can be replaced.

How to fix door handles: Tighten the screws on the handle. If that doesn't work, replace the screws. If that still doesn't work, unscrew the doorknob and remove it from the door. Pry off the metal plate covering the screws holding the doorknob in place. Replace or tighten the screws, then put everything back together.
