"Replace with a new key to improve security"

At first, I understood that a new key would be attached to the front door, but when I checked again at the site, I was told that the client wanted to replace the current key because he wanted to improve the security of the current key.

ALPHA DAC II was attached to the SHOWA IS integral lock. The requester wanted a dimple key that would be difficult to duplicate. So I suggested the WAVE key type for W2-DAC. I got approval, so I'm going to exchange it.

There were no particular problems, and it was completed smoothly.
