Nuki Ultra without universal cylinder

From what the mounting plate looks like, there might also be an option to mount it on traditional lock cylinders with 2-sided tape. Will it be possible to use the lock if one reduces the key size to fit the yellow ring?

Here is a picture of the new mounting plate (from: https://www.youtube.com/watch?v=BpIt_J3c-GQ)

other side looks flat, perfect for 2-sided tape:

From what I can see if you manage to cut your key so it fits into the yellow ring, then you should be able to enjoy ultra lock without changing the cylinder. The tricky part will probably be cutting the key so the center stays at the same spot. Did I miss anything?

This is interesting. I have a cylinder with a knob, and looking at the pictures, I think it might be possible to 3D Print the gear with a different shaped hole in the middle, that fits the knob cylinder.
Only problem would be attaching the plate to the cylinder, since the clamping mechanism like with the old nukis doesn’t exist here. Doublesided Tape might work, but might not be optimal. Alternatively it might be possible to also 3D print a different attachment plate.

I would assume that double sided tape (3M VHB) should work just fine for the “gentle” mode, not so sure about “insane” mode, as that does seem to have quite a bit more speed. I would be doing this just to reduce the noise, as that is the only thing bothering me with my current nuki, so gentle would be the only option anyway.

From what it looks like you will need to 3d print a spacer so the yellow part is at the correct height. If you have a resin printer, you might be able to do the gears as well, I don’t think you will get the necessary stability with fdm prints.

Are there any key copying services that can also cnc the key on the other side?

No :wink:

Speed is very addictive …

Hi @Juergen,

do you mind sharing the dimensions of the rectangular opening of the yellow plastic part? And how much it needs to stick out from the “Beschlag”. I found a company who offer cnc keys, so i want so check if they can make one for me.

Thanks

Maybe we’ll see that yellow gear at least for knob cylinders for some manufacturers. Like Nuki offered before with the knob adapters. I bet the list of customers who are willing to use the Nuki universal cylinder is much smaller than the list of potential Smart Lock Ultra buyers…

Hi, what cylinder do you use? I also plan to create an adapter for a Keso Knob Cylinder as soon as I get my hands on the new Nuki.

An Abus one with a knob. Works perfectly with a Nuki 3 Pro

Mine is an EVVA Akkura 44 Knob.

Good approach, the cylinder is not an option for me either, I wrote to support in the first step but only got blabla as an answer.
I think we need technical data from the plate and the drive adapter, I currently don’t see any problem in using existing knob cylinders and key cylinders accordingly.
I will wait and see whether support provides the technical drawings or answers the questions accordingly and then we’ll see.
