MIWA U9.DAF, inspection and repair due to locking malfunction

"I can't lock the front door"

The site was on the corner of Ekimae-dori. It's a spot that is in trouble with the parking lot. The coin parking next to the apartment was 20 yen for 220 minutes, and 30 yen for 200 minutes when going around the back side. I will walk a little, but I will park in the coin parking on the back side.

If there is a coin parking that can be compared immediately like this, it is not often found. I was lucky.

Well, when I arrived and checked, there was a two-lock cylinder on the front door. MIWA U9 cylinder. The property is 19 years old, but the deterioration has not progressed, so it seems that the cylinder was replaced in the middle of the move.

When I put the key in it doesn't turn completely. I was able to disassemble it according to the procedure, wash it and improve it.
