Needing a new lock for sliding patio door

Question

We lost the keys to our sliding patio door and am looking to replace the cylinder with new keys. Not sure of the door company, but the information on the door is:

16CFR1201 CU
ANS1Z97.1 1984 1-8U
SCC-1100 401 1103
Herculite K

Pictures of handle and lock are attached. From my measurements of the lock are;

Height: 1 1/16"
Cylinder Length: 1 1/4"
Tail Length: 3/4"
Top Plate: 1.0"

Tail Length on Latch: 1.0" Latch (white) tail appears to be twisted but does not look broke. Not sure if the tail should be all one piece or two separate pieces.

Thank you for your continued patience with us. If all you're looking to do is replace your key cylinder, our 82-310 should do the trick. I noticed you also mentioned a twisted thumb lever. That could be a cause for concern. You may wan to consider replacing it with our 82-106.

If you just want to avoid all of that and just replace the complete handle set, our 82-035 and 82-315 will work. Have a look video that shows how to add the key lock to the handle set. This may answer any additional questions you have.
