Use a shorter screwdriver, so it doesn’t slip out and strip the screws.
If there is no indentation in your faceplate, use a thinner tool like a knife to carefully pry the faceplate away from the door. Otherwise, grip the top and bottom of the faceplate and try to turn it counterclockwise. It should release and pull off immediately.
If the latch plate is covered in paint, remove it with a knife before trying again with your screwdriver.
If the latch doesn’t have any screws, it may be a “knock-in” latch that’s just tightly secured in the door. Try to just pry it out with a knife or flathead screwdriver.
Don’t force the latch into the hole. Make the hole larger until the latch fits inside easily.
The center bar will usually be square while the bars on each side of it will be round.
Sometimes the faceplate is attached to the knob itself. Hold the faceplate as far back as you can so you can see where to start the screws.
