Setting Lock Mode on Fibaro Key Fob in Z-Wave JS

Hi Everyone,
I have a Fibaro Key Fob included in Z-Wave JS using an Aeotec z-stick. I am now trying to set lock mode on it as per the instructions here: KeyFob | FIBARO Manuals
I have set parameter 1 and 2 as described in the instruction:
and then woken up the device so it accepts the parameters.

Now I can see that the parameters are correctly set, but the device still wont lock! Any idea what I’m doing wrong?
The manual also talks about setting a Command Class - am I able to do that somehow?
