Pannier locking mechanism

[The Dave]

The locking mechanism on both panniers on my 02 1300 have decided to start playing up around the same time.
Closing the left hand side has been an occasional PITA but now both have decided to become very fussy to both lock/open or attach/detach.
Should I be looking for any known issues?
Thanks

I'd take them to a decent locksmith to see if they can sort them out.  We have a really good one in the southern suburbs of Adelaide that I've used from time to time, but that may not be of any assistance depending on where you are.

I t might seem stupid but have you tried spraying the mechanism and inside the actual lock with some silicone spray such as this?

I had one of my panniers behaving similar what I discovered was after removing some crash bars I hadn’t torqued the rear bolts on the foot peg plate properly and they had loosened which seemed to misaligned things
Hope you are able to sort the problem

I’ve used that fix several times.

I use CRC Powerlube with  teflon on "pie warmers", panniers and top box.

Graphite powder does well and doesn't attract dirt. All my st1300 locks get it a couple of times a year after my panniers started do that

Is it the locks themselves or the catches?

The catches on mine got very stiff and generally un-cooperative when it came to opening the bags, so I removed them and cleaned years worth of dust and debris out of the linkages, then hit them with the silicone spray and they were good to go.
