PR.DAF + storage type with lid (with eccentric function) crime prevention thumbturn malfunction repair

"I want to request repair because the key does not go all the way in."

It was said that the key could not be inserted all the way. It is a double door of PR cylinder, but the hardness was confirmed on both the top and bottom.

Especially the lower cylinder seems to be hard.I was able to improve by disassembling and cleaning the cylinder.

It wasn't unlocking work this time, but a security thumbturn was installed.

A retractable security thumbturn with a retractable lid with an eccentric function.There are parts that you can't understand unless you look into it, but you have to check the position of the thumbturn lid when it's locked.The unlocking direction is determined by the positional relationship with the deadbolt.It's a troublesome guy, so you need to adjust the force with crab scissors.

The position of the lid when locked is vertical.After opening the lid, it becomes the work of crab scissors in the vertical position.It also has an eccentric function.
