NAGASAWA's tubular lock replacement of living room empty lock and toilet display lock

"The key in the room is not working properly, so I would like to ask for an estimate for repair or replacement."

It seems that I called several companies and got a competitive estimate. What company am I from? When I presented the estimate, it was approved as it seemed to be more reliable than others. Thank you very much. I'm happy.

Well, let's first check the situation of the toilet near the entrance. The lever handle and latch don't seem to work together. The key from the inside is also uncomfortable. Disassembly is required.

As for the empty lock in the living room, there is also a sense of incongruity in the interlocking of the lever handle and the latch. Both are defects of tubular locks.

Both are long seat locks of NAGASAWA. When disassembling the empty lock in the living room, the tubular is completely broken. It looks like it was damaged by force. I need to replace the tubular lock. Let's say you check the toilet side and unload it from inventory.

When the toilet lock is also disassembled, the center part is broken here. This also requires tubular replacement. Moreover, the leaf spring of the thumbturn part is also broken. It's just broken, so the key will work properly. However, it just doesn't have a click feeling, so if you don't mind it, you can use it as it is. When I explained that, it was said that it was not necessary to replace the set, so it seems that there is no problem even if there is no click feeling.

The stay of the pull-leg made of resin was also broken, so it seems that there is no choice but to fix the resin cover directly to the door with screws. The exact cause is unknown, but I think it is metal fatigue damage due to aged deterioration.

Based on these results, I decided to replace both with NAGASAWA backset 51mm tubulars.
