That'll do it

The sliding patio door into my garden office has needed some adjustment for a little while now as it has been difficult to lock.

The suppliers of the office are very helpful, they supply the necessary tool (a long hex wrench - I can't say Allen Key as it's a registered trade mark!), but they don't give you the instructions of what to do with it when installing the building.

A quick email got me the necessary information in the form of a YouTube video and a PDF document. Although dated for a later model all that seems to have changed is that the newer ones have a Philips head screw instead of the hex bolt. The instructions worked and the door is easy to lock again.
