Before we answer your question, could we see a photo of the mortise lock you have been using?

Here is a pic of the lock. All it says is ? made in USA? on it. I can get a pic of the handle also later. As you can see the keyway is vertical when hook is extended. Unlike the 45 degree lock. Thank you

Thanks for the photo. The closest match we have is our 82-223 mortise lock. This has a 90 degree keyway, however, it has a square face. You would need to square off the edges in the cutout in their door.
