Obviously, tried some WD 40 type stuff. No success.

Could have just latched it open, but they don't have a key for the fitted
mortise lock.

Are you sure there isn't another key somewhere? If the outer rim lock
has ever been replaced, its key may no longer match the
inner part.

When we had problems with our Yale lock I assumed the cylynder
was worn so I contacted Yale to ask if they could supply a
matching cylinder or, if not, a new matching pair.

They replied that they couldn't but suggested it was extremely
unlikely to be due to wear and suggested trickling some light
oil into the slot.

I did and it worked - and has continued to do so ever since.

I'm not sure WD40 would work as well as it isn't intended for
use as a lubricant.
