MIWA U9.LA Large obstacle behind the door, switching from normal unlocking to gap unlocking

"Lost key, Unlocking the entrance door"

It was planned to be completed with normal unlocking of MIWA U9.LA type.The opener could not be placed in the proper position.Something big is blocking the door.I can't reach thumbturn no matter what I do.

It looks like a large-capacity wire rack with a magnetic width of over 30 cm.It was pasted right under the door scope.However, I can't seem to remove the magnet.

I have tried several times, but I have to change the unlocking method.I changed to the method from the gap and was able to unlock it in a few shots.

2mm wasn't enough. Changed to all-purpose 1.5 mm compatible with smoke guard.This is the first such case.
