U9.LA Foreign matter mixed, tumbler disassembly, cleaning and repair

"If the key does not stick, the key will malfunction"

Certainly, the key cannot be inserted at all just at the beginning.It's not a tough situation.
From the client's behavior, I am worried about someone outside, whether something was done by the stalker.

Since I left the scope in the parking lot, I can only see it in a dark place, but I don't feel that there is a foreign object near the insertion slot.

Was it even applied with adhesive?
But the first pin seems to move normally.
(It doesn't look like glue, but make sure you carry a spare scope with you.)

It's work in heavy rain and strong winds. (This seems to be difficult) I have no choice but to disassemble it, but even if I take out the inner cylinder core, no abnormality can be confirmed.
(Is this the only way to get rid of everything?)

Pin XNUMX does not work at all.Something is caught.I don't want to disassemble it anymore, but I can't take it out easily.
When I finally took it out, about 5 mm of the tip of the toothpick was completely sandwiched between the tumblers, like a wedge. (This does not improve just by cleaning)

I noticed that I was trying to get rid of the foreign matter and put it back in.There are a few tumblers spinning around and they aren't in place. (It seems that he was mischievous quite relentlessly)

It doesn't look good in the dark.Switch to reading glasses + magnifying glass. (Oh, it looks good) When I was working while pushing in that too small leaf spring, the spring came off. (Acha Korya) Moreover, the tumbler in the middle.

(This is really all loose.)

Be prepared and start work.Work very carefully so that the parts are not blown away by the wind.Did it take about 50 minutes after all?
