Schlage Z Wave Plus

Hi Guys,

This is the first time I am asking help from the community so any help is appreciated.

I live in Australia. I bought Schlage Z Wave Plus door lock from Amazon and the lock came from US. As far as I know, it is Z Wave operates in different frequency in both countries (US 921.42, Australia 908.42). Also, in Australia 921.42 is used by mobile phone frequencies. I just found out it is illegal to use US Z Wave device in Australia. Is it possible to use the US Z Wave device in Australia by changing the frequency of the device itself? Or do I need to return the device? I unbox the device and tried connecting it with Homey Pro and it’s not pairing.

Any help is appreciated. Thanks!
