Tilt latches that are internal, broken
Thanks for your post! I'll need to see the internal latch removed from the sash to determine the best replacement option. Unfortunately, the latch lever does not give enough information to identify the hardware.
Take a look at the video tutorial below for a detailed demonstration. Don't hesitate to reach out with any additional questions!
I'm sorry to say there is no other way to remove it. The next best suggestion we have is to convert the sash to one that uses surface mounted latches. In the video below, we suggest using the 26-228 and 26-229 but any one of our surface mounted latches can work for this solution. They can be viewed here: Surface Mounted Latches.
