MIWA RA, Unlocking the entrance door and cylinder replacement due to foreign matter entering the keyhole

"Unlocking the entrance door for contamination"

The client can't open the front door with the key because he was mischievous with something like glue. The phosphorescent part of MIWA PR.RA was discolored. A long stay escutcheon also had traces of fluid flow.

Even if I tried to insert the key, I could not insert even 1 mm. It was mixed into all the keyways quite carefully. Furthermore, it was also applied to the gap between the cylinder and the long seat escutcheon.

Unlocking the entrance door completed with normal thumbturn unlocking from the doorscope. After that, it is exchange to U9.RA cylinder. He said that he was planning to move soon, so he didn't need to use an expensive dimple cylinder, so he chose the U9 cylinder, which has good cost performance.

It seems that the police were there, but they said in a strong tone that they would not intervene in civil affairs, such as installing security cameras, patroling but not being able to do it all the time due to lack of personnel. It seems that the police response to such stalkers and pranks on keys is according to the manual.
