Mul-T-Lock.HMD, air jack assisted unlocking of hard entrance iron door

"Lost key, Unlocking the entrance door"

It is said that he went for a walk in the neighborhood and dropped it somewhere.I searched for it but couldn't find it, so it was a request to Unlock the entrance door.The location is Shibuya Ward, near Shinjuku Station.Start by finding a parking lot.I went around the neighborhood and found a small coin parking.It's not on the map.There is a maximum charge.It's safe.However, high prices should be avoided.

Since it was a knob, I will check the direction of hand and judge the unlocking direction.I moved to normal work, but I could not unlock it obediently.

The deadbolt can be seen through the gap, so it does not move even if you observe its movement.

So one word, "It's really hard," the client quietly said.

It looks like the door was warped.It is said that it has been in this state since the Tohoku earthquake.This iron door is quite heavy.

Zoom in on the deadbolt and you'll see it's completely on the strike.There is a choice of whether to push it up with a special screwdriver or with an air jack.In addition, spread it in the direction of the hinge.

I checked the gap between the deadbolt and the strike and unlocked it.The work was completed quickly, but when I checked the strike, there was evidence that about 3 mm had been shaved.At that time, the worker made an appropriate decision.You must have used an electric file to do the work.
