MIWA LB.10PGF713, Lost key, Unlocking the entrance door

"Lost key, Unlocking the entrance door"

Since this is a newly built property in Tokyo, this type of thumbturn is supposed to be a security thumbturn. We will proceed with the work using tools for crime prevention thumbturn. I tried adjusting the distance from the door scope to the thumbturn with an extender, but it didn't seem right. However, the work was still possible, so I continued.

I was able to unlock the top side smoothly, but it took quite a while to unlock the bottom side. As expected, the lower part is more difficult. I was able to unlock the lock in 20 minutes by trying to keep it from slipping and determining the position. The average concentration span is 20 minutes.
