Need keyed lock handle for Phillips Series 870 sliding patio door

A home owner from USA says:
We have a Phillips sliding glass patio door -- it's a "Series 870", "CCMC# 12765-L". It has a
locking door handle with a keyed entry on the outside. The locking mechanism is broken, so I need whatever would be the most appropriate replacement part, whether it's an entirely new handle/lock mechanism, or just the lock itself. Here are some pics and dimensions:

Length from the end of the screw to end of the screw: 4 7/8"
Length of entire silver metal piece: 6"
Door width: 1 1/2"

I'm not sure what's broken, exactly. Do you mean the inside mortise lock or the key cylinder itself? If you need the mortise lock, see our 82-226. If it's the key cylinder, see our 82-310 instead.
