MIWA.U9 Cylinder replacement due to broken key

"The key is broken and remains inside, so I would like to have it inspected, repaired or replaced."

33 years after construction, the shared cylinder at the entrance of the condominium was MIWA.PR.I wonder if I broke the PR key.

However, the front door had U9.LA. (It should be quite powerful to fold even U9 ...)

The broken key remained firmly inside, but it felt a little strange.It was exchanged immediately after the quotation was approved. (Let's remove the key later) The work is finished immediately.

After checking the removed cylinder, I found that it contained adhesive (this was what it looked like).Even the core alone does not come off at all.The tumbler was stuck, but I don't know why.
