Put a piece of pipe over the handles and work them a few times. Mine have loosen up after use and I may have to install the shims again.
Two of mine have one of the two shims and the other two none, presently.

I do not know where the OP went, put I have recent experience with the Demco picture frame and provided the answer he was looking for. A piece of 1" SS boat railing fit over the lock handles, once I cycled them a few times they now lock and unlock easily. And I may be reinstalling shim washers.
