Remove the door handle

Starting from the inside of the door or the side without a key would be beneficial. You’ll see a little hole close to the spot where the handle and door meet, and your latch has a device with a tiny sharp end. To remove a door handle from the main cylinder body, insert this pointed end into the hole and release the spring clip.
Use the tip of a wire coat hanger or a toothpick if the poke tool with your new latch box isn’t long enough to release the catch.
Take hold of the ornamental latch’s decorative cover, a rose, and turn it clockwise for about half an inch. Repeat with the lid of the jam jar. It should start tugging directly in your direction. The inner surface of the support plate is fastened to using a rose insert and two screws. A little piece of engraved metal in the form of a throwing star is attached to the support plate. Two screws are in the plate. To remove them, unscrew them with a long electric screwdriver. You should also put the remaining lock components on the other side of it together after you remove the two screws.

Replace the latch bolt

This may be a tricky task because it can be loose or uncovered or the previous locksmith did a lousy job. The screws have funny-looking, as one end half is like the threaded look and the other head half is like a machine threaded.
