NAGASAWA KODAI thumb-latch lock Inspection and repair due to operational defect

"I have the key, but I can't pierce it."

It was a single house for an elderly person over 90 years old. Since he couldn't find a locksmith, he asked a neighbor to do it for him.

Arrived at the specified address but not the target home. After all, it was an address that was off by one block. I couldn't find the target when I called, so I had a hard time finding it.

It was a hot day, so the elderly man was resting in the shade.

After hearing and confirming, it was said that the key does not stick all the way. It seems that it was replaced with a new one several years ago, but it is too early for aged deterioration.

First I cleaned to the cylinder, but this time this was an improvement. There was no need to disassemble it.
