Advice on Mortis Lock and Inside level required

A quick learner from Guelph, Canada says:
I have purchased a 82-310 Key Lock (2nd item to left in picture) for my Patio Door, so I can lock the door from outside. Can insert the lock into the outside handle. Now realise I probably need a new mortis lock and lever to lock from inside.

All other items in the picture are the old parts. Please advice.

Take a look and compare our 82-030 handle set, as well as the 82-211 or 82-214 latch and keeper sets to your original hardware. Thanks for posting!
