New U9.LA-U1 security thumbturnUnlocking the entrance door

"Unlocking the entrance door without a key"

It is listed as a 36-year-old property.There seems to be no problem because it is declared as a normal thumbturn with one lock.

When I arrived at the site, it was certainly an old property.However, looking at the deterioration of the entrance door, lock, and door scope, it is quite new.There is no evidence of peeling due to rust.

When I asked the client, it seems that they had already been remodeled when they moved in for two years.

If you try with a normal jig, the thumbturn will not turn.If you trace it with the tip and explore it, it seems that there is a circular part.When I showed him the picture, he pointed to U1.

"By the way, there was a button."So I changed to a special jig and unlocked it while showing the video.

I remembered that I used to overdo it and broke the opener.
