MIWA LZ1x2 kitchen doorcylinder breaking and unlocking KABA3258 cylinder replacement

"Lost key, Unlocking the entrance door"

It was a detached house like a residential park.The entrance lock was a PR.PGF703 push-pull door handle type.I just ran out of stock the other day to unlock it.Explore other entrances.

I heard that there is also a kitchen door, and when I confirmed it, it was a double cylinder, probably U9.BH, so it is possible to replace the cylinder after unlocking.This time, considering the work environment at the site, I chose to work with a hole saw.

The hole saw proceeded with free cutting at φ22 mm and φ18 mm (there was no washer spacer for hole saw measures, but it was cut a little too much).

(A hole saw can't be used twice at most. It's an expensive consumable item. It's really a cousin who wants to break the lock with a grinder.)

It took about 30 minutes to unlock, but there was still a door chain. There was a suggestion from the client that "it's okay to cut it," but that is not necessary.

After unlocking everything, when I checked the carved seal, it was LZ.When I checked the screw pitch for mounting, both the upper and lower cylinders were LZ1.However, U9.LZ1 has only one in stock.Of course, LZ1 cannot be installed because the screw pitch is different.

Use KABA ACE1 which can support LZ2 and LZ3258 with the same key.I reconfigured it to the same core and attached it.
