MIWA JN.LA, cylinder breaking and unlocking of entrance cylinder with thumbturn cover

"Lost key, Unlocking the entrance door"

It was a property in front of a certain private railway station in Tokyo. But there is no parking space. 5 minutes to search nearby. After all, I parked at the coin park, which is a 7-minute walk one way.

I tried to proceed with normal thumbturn unlocking with MIWA JN cylinder.There was a sense of incongruity immediately after starting work.When I heard again, it was said that the cover was attached.I forgot to check before starting work.

When I checked with the camera, I could see the U-shaped thumbturn cover.It seemed to be attached with adhesive tape, so it didn't move easily.It takes about 20 minutes round trip to bring the unlocking tool, so I stuck with normal thumbturn unlocking.

However, the work did not go well, so I returned to the work vehicle after all. Considering the work space, I decided to drill with a hole saw for JN instead of a grinder this time. I pulled out the core cylinder and finally unlocked it with a special screwdriver. About 40 minutes had passed since the start.

After that, the U9.LA cylinder replacement work is completed.

After unlocking, I considered it, but the thumbturn cover was not fixed as firmly as I thought, and if I changed the angle of the tool a little more and adjusted the force, it would have been better not to break it. It may be.Let's do the next homework.
