U9.10PGF713 Crab scissors method even with standard thumbturn

"The entrance due to the loss of the key"

It was a thin PGF713, but a standard thumbturn.It is a rare combination for a relatively new property.

At a short distance, I tried the tip jig for pull that I made from the positional relationship with the door scope, but it did not work.After all, I chose a careful method and changed to kani basami.

I proceeded with the old-fashioned exploration method, but it didn't come nicely.Perhaps I didn't practice enough, I needed a camera here.
