SHERLOCKⅡ＋B5 Unlocking the front door

"Unlocking the front door due to lost key"

Although it is a SHERLOCK II card key type, it has a door scope, so it tries to unlock the thumbturn from the opener.It is a crime prevention thumbturn with a switch by hearing.Then it will be U1 or B5.But it might be GOAL. (This handle was a MIWA handle)

When confirmed by CCD, it turned out to be B5.All I had to do was pay attention to the door guard and turn it with a special tip jig.
