I struggled to learn fingerprints on 1 of my 3 keypads for over 6 months now.
Currently on 2.3.2 and not in beta program.
This one is connected to an Opener, that is also connected to a bridge.
I have tried this with Samsung S24 Ultra, S25 Ultra and now S26 Ultra - and today even with an Iphone 17 Max.
Symptoms unchanged:
After successful pairing and entering open code the part for fingerprint learning it suddenly claims obscure error.506 which seems to be a sudden inability to com via Bluetooth - which is a nonsense error as BT worked fine to this point, and after… just not for learning fingerprints
After error.506 it claims to retry, which also fails in an endless loop, and and the keypad itself leaves maintenance mode way faster than the 3 minutes (the rotating blinking stops) - essentially right after the first error.506 and no matter what the app says it would try, from reconnect to “reboot keypad” does anything to the keypad… 
Will this beta finally have proper error messages here, or even be able to.learn prints as expected and known to work?
Do I need to get into “developer beta” to get this beta on my device to continue trying to use THE core function of Keypad 2 that justifies its price?
And if yes, how?
PS: UPDATE: needless to say I struggled another 2 hours today trying all sorts of hacks and workarounds I could read about - including unpair/factory reset/re-add/re-disconnect, new users, new codes and what not… the symptoms remained the same
I’d try to remove the Keypad from the Opener, factory reset it and re-add it to the Opener again.
If that does not fix it please contact customer support via the Nuki App (Menu > Help > Contact Customer Support) as this is an individual issue which requires to share logs and other sensitive informations.
This forum is focused on developer and beta related issues.
Hello
I have been watching this thread for some time and was wondering if there will be a final Version (not Beta) or at least a Release candidate. I have seen a lot of Beta Versions 2.4.x and now 2.5.x
My keypad2 runs on 2.3.2 still but I would like to participate on any improvements by newer Versions.
Will there be a final version soon?
Thanks
Hello Tobias,
thanks for your interest. Rest assured, we will inform also here as soon as we have the next public release for the Keypad 2. But we do not comment about future release dates.
Please keep following us here to stay up to date.
Best regards

I’m very disappointed by the beta so far.
The keypad is failing to open the door basically every single time when it wasn’t used for some time.
You press your finger on the pad and then you get the LED animation from going back and forth.
Most of the time this also happens a second time.
The third time it shows the proper unlocking animation and opens the door.
This happens for all 3 people and their saved fingerprints.
I think the keypad looses the connection and falls in a kind of sleep mode.
The first two fingerprint attempts are waking up the device forcing a re-connection over the next seconds which leads to a successful opening of the door.
What’s pushing my theory even more:
When you use the keypad directly after a successful unlock it will NOT fail a single time.
Only when it was not used over a longer time period.
Hello Sebastian,
if you Keypad has connection issue to your Smart Lock please follow these troubleshooting instructions:
Thanks a lot
Hello,
the new public release 2.5.1 is available now and all users who are not in the beta can also benefit of latest improvements.
Thanks to all Beta testers

Hi Okko,
These are Bluetooth troubleshooting instructions to improve connection between Nuki lock and smartphone.
How does this help with the connection between keypad and Nuki?
It should completely work without my phone.
I open the door by fingerprint not via my mobile.
Also I haven’t changed anything to my setup.
It was working before .
Nevertheless I switched now from “Automatic” to “Balanced” in battery settings of the lock.
Will report back if it improves anything
Hi Sebastian,
those are troubleshooting instruction for any bluetooth connection issue of the Smart Lock. Your phone, a Nuki Keypad or a Nuki Door Sensor are all connected via bluetooth to the Smart Lock.
I hope those are solving the issue. If not please contact our customer support.
Thanks a lot
