Does the NUKI also work on doors where there is no latch on the outside and the door only opens by pushing the bolt back with the key? And if so, does the NUKI hold back the bolt permanently or only for a short time, as is the case with automatic door locks in apartment blocks?

Question

Accepted Answer

If you mean a snap lock, I'm sorry to tell you that it doesn't work. I tried this myself and was unsuccessful. Nuki can only work with a normal key/knob cylinder, either open or closed.

Answer

Yes, that works. In addition to the "Unlock" function, there is also the "Open door" function. This function retracts not only the locking bolt but also the retaining bolt. The "hold time" can be set in several steps from 1 second to max. 30 seconds.
