Exterior door handle sets should provide a quick and secure way of entering and exiting your property. If the handle or lock is damaged or broken, you might find the door is difficult to open, close or properly secure. Inspecting the handle set and fixing any damage is often relatively straightforward. Many common issues can be fixed relatively easily with basic household tools.
Slowly close the door, paying attention to how the latch bolt lines up with the strike plate in the door frame. If the plate is too high or low, the bolt will not click into place when the door is closed. To raise or lower the plate, loosen the screws at the top and bottom and remove the plate from the frame. Drill new holes slightly or lower, depending on your needs, and tighten the plate back in place. You might need to chisel away a little wood to establish the correct position.

Remove the screws on the inside door handle and pull both handles off the door at the same time. Inspect the insides of each handle, making sure both move when the handle is lowered. Make sure the square metal rod running through the mechanism turns the latch mechanism. Consider installing replacement parts if the handles do not turn the rod.
