YKKap/ALPHA key EC-Z1 EC-Z2 Emergency core cylinder cylinder breaking and unlocking due to child confinement

“Cylinder breaking and unlocking due to child confinement”

It appears that a one-year-old boy is trapped inside. Apparently, I followed my girlfriend's mother out to take out the trash and accidentally turned the thumbturn and locked it. It appears to be a newly built single-family home that we just moved into 4 months ago.

I checked the surrounding area, but it seems like I have no choice but to break the lock. I asked her mother to call out to her from the front door and ask her to come out from near the door.

Since this type of lock cannot be broken with a hole saw, I proceeded as usual, using two types of rotary files. It only took one spot on the bottom, so it didn't take much time.

The replacement cylinder (HH5K15557) was out of stock, so it will take some time to obtain it. However, since it was still within the warranty period for the house, it seemed likely that the insurance would cover it.
