Odd problem picking to control
Finally I got one of them to pull and took it out to the van, dumped, measured and made a control key. Back into the building armed with the newly made control key and something else happened. It turned to control and at the last millimeter it went over to operate! Then the core came out. Whoever pinned up these cores the last time made some serious mistakes. Every core would turn to control then you could continue to operate the lock.
