Replacing the tilt in latch

Sure, hopefully we can help. To remove the 26-334 internal latch, you first slide a flat tool under the finger lever to detach it from the internal latch. The internal latch is screwed to the sash under the top cover. The top cover might be tricky to remove. Be careful not to damage your window when removing the cover. First, look for any screws that may be holding the cover down. If you cannot find any screws, the cover may pop off if you slide a flat tool between the cover and the window.
