Wow those locks look cool. First one I’ve seen that is small enough to replace the old door lock in my condo without having to drill new cutouts.
Unfortunately, it appears they likely won’t work with the xNT. Here is an email I sent, along with the response:
I see that the Ultraloq Combo (and your other locks) support a 13.56 MHz key fob. Do these key fobs use a standard NFC chip? I’m looking for the ability to pair the lock with an existing NFC Type 2 NTAG216 device.
Ultraloq doesn’t support any third party fobs. you need to use Ultraloq Fob. Thank you.

I’m hoping the service rep. might be wrong. I wasn’t able to find any specifications on the RFID capabilities of the lock, other than it uses 13.56 MHz. Perhaps the key fob’s include additional data in the NTAG records that could be cloneable. I did confirm (via their FAQ) that new key fobs can be purchased and enrolled via the smartphone app, so they must be using some kind standard.
