Lever tumbler lock repair
Kagiya-Morioka-Ben locksmith service"Key exchange estimate" I took it off myself, but I couldn't get it back.
The venue is a boutique that sells antique items. The cute door stands out. The object is an old tumbler lock. However, it doesn't seem to be used. It seems like the door knob won't return, causing the door to open or not open on its own.
The store manager was also investigating by himself, and it seems that he had a hard time choosing to replace it, but for the time being, he hoped for Nagasawa's KODAI NEO lever type.
I explained that depending on the condition of the hole in the door, there may be holes that cannot be closed.Even if you replace it, the existing auxiliary lock will still get in the way when you replace it with a one lock / thumb-latch lock.It's hard to find a replacement lock, so if you can open the lock case and repair parts such as the spring, it seems that the door modification will not be a big construction.
I will remove the parts for dimensioning, but probably because of some miscellaneous processing, one screw on the front is not fixed. (Since the wood in the back has been scraped, the screws are useless.)
After a series of measurements, I decided to ballast the lock case.When you gently remove it, there is one place where the push spring is broken.There is no damage to other parts.After checking the configuration, I inserted the spring that had been purchased with the adjusted length. (The operation returned to normal with a good feeling)
The rest is the processing of the screw hole on the front and the processing of the set screw M6 for fixing the grip ball.Adjust the set screw by cutting the length with a glider.Grease was also applied to the moving parts, and the silicone lubricant was also pointed to individually to complete.
I managed to complete the goal in 1 hour.This tumbler lock, plate thickness, front plate, etc. are more than 2 mm, and it is quite robust.I will have another 10 years.It seems that the key relationship will be nominated in the future.I need this kind of relationship with the owner. The owner said, "I received a call from another company that does not support keys without cylinders."The vendor doesn't know the marketing.
