That’s not the case with the L&R locks I own. The hole is in the fly and the pin is in the tumbler. L&R even specifically mentions a couple of times in their instructions (something to read when all else fails) how to correctly install the fly. Here is a photograph I provided someone for reference quite some time ago when they were having a similar problem with an L&R lock. Note the hole in the fly and the pin in the tumbler.

Then you likely don’t have an L&R lock, so the issue must be something else. But IF you have an L&R lock/boat anchor, the fly in your photograph is backwards.
