MIWA U9.DH lock, key replacement due to key loss

``Lost key exchange'' It was a certain Japanese confectionery shop in the prefecture.

The carved seal was U9.DH and the cylinder was DA. It is the first time for DH to be engraved.

The comb pin is non-removable.I replaced the core and installed it, but even if I turn it, it will spin.It took some time to find out, but there was a mechanism to make the case idle.

It is a specification that the dead bolt does not come out unless it is turned 270 degrees. Turn it further and the key will come out at 360 degrees. The core ended up upside down anyway. This is also within specifications.
