LSPnormal thumbturn unlocking but not thumbturn

"Lost key, Unlocking the entrance door"

Of the two locations, the one on the lower side was requested to unlock.If you look at the pictures in advance, the upper cylinder is quite up.Therefore, I thought that the unlocking on the lower side would be the main lock.

After confirming the situation at the site, it was completed with normal thumbturn unlocking.When you open the door and check it, there is a large thumbturn on the MIWA LSP lock. It is often used in USHIN-SHOWA, but it is quite rare in MIWA.

However, I was surprised that there is no thumbturn for the DAF, which is the main tightening auxiliary lock. It has a U9 cylinder.If it is a lock unlocking here, the work will be limited to unlocking.It has been there since I moved in and I have never used it, so I suggested that it would be better not to use it as it is.Because it will be troublesome when it comes to emergency. (I don't know about the other rooms, but it doesn't seem to make much sense to increase security. The room is also on the first floor.)

Since the outer cylinder uses PR, you will have two types (though many people find it troublesome).
