YKKap PSDN.TE18-J, I can't get the key out of the front door.

"I suddenly couldn't get the key out."

It was a case of unlocking the entrance door of a detached house. As far as I checked the address on MAP, it seemed to be a fairly old house. When you arrive, the front door will be brand new. Looking at the cylinder, it has a YKKap insulated door specification. The key was inserted vertically into the PSDN.TE18-J BLACK insulated cylinder.

When I put the key back on the side, it came out normally. I checked it several times, but no defects were found in the operation of the cylinder. When I asked about it, I was told that it had been renovated. From what I've heard, the keys in the lock set I've been using for decades were probably oriented vertically. Sometimes something like this happens. A little spray cleaning and the job is complete.
