Attaching a thumbturn with a key to prevent loitering

"I want you to put something on the front door to prevent wandering."

A long time ago, it seems that the thumb-latch lock was replaced with a lever lock.It was because my parents were difficult to handle.

There are quite a few projects to prevent wandering, but this time I added the one for LSP to the inventory.

I don't want to replace the thumbturn for LA on the main lock.I think it's because I remember how to use it.I don't know if the double-sided cylinder is locked, so I don't want it.

KABA's keyed thumbturn was proposed.You will also need a decorative board.It became an entrance full of escutcheons.
