How to fix the latch on a sliding glass door.
Most sliding doors have a mechanism called an adjusting screw located at the bottom of the door ends.
Locate the two adjusting screws at the bottom of the door on the face or edge of the door and pry off the trim caps that cover the screws.
If the door becomes even harder to open turn the screw in the opposite direction.
First remove the screws securing the door handle in place first with your phillips screwdriver and slide the outer latch lever out of place.
