Sha-Maison SEKISUI HouseUnlocking the entrance door

"Cylinder malfunction Unlocking the entrance door"

There is a key, but the cylinder has stopped turning at all.When you look at the key, you can see that the silicone head has a Sha Maison engraved on it.Was it so?This handle combination is a Sha-Maison type. It is a combination with Normal Patante Patante (the one without a seal to turn while pressing).However, unusually this time there is a door scope.Moreover, it is located right above the thumbturn. That's what Sekisui House is likely to think of.

Well, I did the cylinder spray cleaning patiently for about 15 minutes.There is no improvement.

Change to thumbturn unlock from door scope.The upper part was finally unlocked after changing the type of camera, the type of opener, and the combination with the tip jig.40-50 minutes including setup.Since the lower part was not used, it was completed by unlocking it as it was.

After that, when overhauled, the cylinder sometimes turns, but there is only a 10% chance that it will turn.Same condition with spare key.I'm worried about the feeling of the pin getting caught, but the probability is too low even if it wears.Probably due to a malfunction of the spring, there is a high probability that the anti-picking pin will remain tilted.

The property is about 10 years old, but the cylinder needs to be replaced.This is a rare case.It takes a month because it is a Sha-Maison specification and a reverse master specification.Moreover, since it is a special specification that is not on the market, it can only be arranged via the management company.Until the replacement, I explained that the upper cylinder was not used and only the lower cylinder was operated.
