Need replacement parts - sliding glass door

Hello,
Our sliding glass door handle no longer functions (locks).

I have attached several photos:
The first 2 are the outside handle
The following two are the inside handle
The last is the actual locking mechanism

The outside handle has no markings
The inside handle I believe have the following 919213
Lastly I believe the locking mechanism states
Canadian Patent 919213 patented 1973
The other side states Patent No 3.596.954

I believe the locking mechanism is the 82-225

I cannot tell what is wrong but the locking arm moves freely and not sure there should be a spring which helps keep in place. The inside handle has an "l" shaped arm as the item which turns the locking mechanism

Can you please take a look as I need to get these parts

Thank you
Rick

I spoke to Ben yesterday and I mentioned the part we originally looked at 82-225 may not be the part as 82-225 has a handle with a black nob on one of the sides which my part does not have.

In speaking with Ben he discussed our dilemma with another person and they recommended part 82-005. I am a little skeptical as my locking mechanism actually inserts into the door itself.

If you look at the first image, this is our door where the locking mechanism is inserted.

The second picture is the piece where the locking mechanism clicks into, then those two pieces gets screwed into the door and the handles are attached.

The third picture is the two peices actually inserted.

If you can please let me know as soon as possible as we do not have a good way to lock our door. We have been inserting a dowel in the tracks.

Thank you for all your help.

Rick
