Inside nob lock doesn't work

A quick learner from Warrenville IL says:

Turning the inside nob -lock- doesn't move the 2 locks on the Aside patio door. They don't seem to locked but the nob to lock the door doesn't work.

The length of the lock is 12.1/2" metal to metal. Any help is appreciated.

Hi, Carol.

This reminds me of our 82-260 mortise lock, but compare our dimensions to yours and see if this matches what you need.
