Unlocking the crescent of a detached property

"Unlocking the entrance door, but don't break it. If possible, open the crescent through the window."

The conditions for unlocking are strict.Apparently, they asked another company, but they canceled the cylinder breaking and unlocking.

A typical 3-story detached house.The entrance is ALPHA's push-pull grip handle type specification, so it is necessary to break and replace two locks.

There is one window when you turn to the back.You will have to unlock it here, but the fence is in the way and the scaffolding is narrow, and there is also a height to the window.

By somehow creating a scaffolding and preparing a working environment, it seems that work can proceed.It is said that there is no lock function, so the difficulty of the work is lowered, but the work posture is not stable after all.

I tried many times and unlocked it.Fortunately, there are some newly built properties that have a gap for inserting the opener.
