The door is stuck in the lock position. Removed the handle and tried using a flat had screw driver to unlock but does not budge.
Any help on how to unlock and replace the lock ?

Unsticking a mortise lock
by: Adrian

I would jiggle the whole door up and down slightly and also push it closed while using the thumbturn lever to try and pull the latch hook back in.

You will need a second person to jiggle the door while you try to open and close the thumbturn lever

These locks have a spring inside that breaks all the time but the latch hook should still move

Its probably jammed in the keeper and jiggling the door should unjam it
