They require maintenance and oiling of the moving parts. This can be done using a thin oil (never WD40) and should be done every year.

If hinges that are sagging aren't the cause, the door could be skewed and catch or hitting the strike plate hole in the frame. The solution is to remove the strike plate, and then use an abrasive chisel, which will enlarge the mortise it sits in. This lets the latch sit correctly in the hole and avoids scratching or catching on the frame.

When the cylinder is out of the way take a measurement of its width using the help of a book or piece wood that fits into the adjustment screw gap above the lock.

Check the Lock's Width

If your patio door latch is hard to turn even after cleaning and oiling it could be because it's not aligned with the strike plate.

Check the holes for receiving of the strike plate to ensure they are clear of obstructions like dirt or plastic plugs. Loosen the keeper screws holding the strike plate. This will allow it to move vertically but it will not be able to separate from the frame.
