Having the separate keypad isn't ideal however keeping the existing lock in place on the front door has advantages also and the existing key can be used if something really goes wrong.
Having said that we have never had to use the actual key so I guess that points to the reliability of the platform.

Thanks, I just had a thought regarding Radio Frequency for Z-Wave. I know the US and AUS/NZ use different frequency bands for Z-Wave and this makes it harder to impart Z-Wave devices for the US as the could be illegal to operate in NZ (RF interferences). Have you looked into this at all?
