Compatibility Nuki Universal Cylinder 1.Gen and 2.Gen

Discussion

Hello,
I own a Nuki Universal Cylinder (1st generation) and have recently purchased the Nuki Ultra. Since I would like to continue using my old keys, I’m wondering if it’s possible to keep the left part of the 1st generation cylinder and only replace the right part with the new Ultra cylinder.

I had similar problem with compatibility of old cylinder (designed for gen4 Nuki) with new Nuki Smart Lock Pro (5th gen).
I solved it by bending a shelf bracket 4cm wide as seen on photo, which simulates a key handle. This works just fine.
