Larson storm door lock set key cylinder

A quick learner from USA says:
Will either 40-123 or 40-089 key cylinder fit a Larson storm door lock/lever set?

Dave from SWISCO responded:
It actually depends on which Larsen lock you have on your door. Larsen uses a few different handle sets. I don't believe the 40-089 will work on just any Larsen door. The 40-123 should fit the 40-212 lock, but make sure that the 40-212 is the one you have. Your best bet would be to remove the existing cylinder and send us a photo of it so we can determine what you have.
