MIWA LESP+TE-08, KABA ACE Special unlocking of door with smoke guard due to cylinder malfunction

"The key to the auxiliary lock sticks in, but it won't turn."

It was a terrace house type property. I've come across similar types of things several times.

When I heard the details of the report, I thought it was due to deterioration over time. However, even if I use it exclusively for spraying, I won't feel it move even one millimeter. I tried spray cleaning several times, but nothing improved.

When I talked to the client about the interim report, she told me, "The child put the key in the bicycle." No damage to the keyhole was confirmed, but I don't know how the child stabbed it and pulled it out, but since it was a child, it must have been done by force. I think that's why the pin was scratched.

I looked through the scope and found that there was no problem with the movement of the click ball in the back, but there was something strange about the top pin near the entrance, but I couldn't clearly see it. In the end, you will have to either break the lock or use a special unlocker to unlock it and replace the cylinder. It will probably take some time to get confirmation from the landlord regarding the broken lock.

Work began with special unlocking. Since there is no door scope and a smoke guard, I proceeded to unlock it with a special tool. Maybe the length wasn't right, so it took a few shots. Let's adjust the tools later.

By the way, there was a doorpost nearby, but it was too close to approach.
