I’m pretty sure if you got a C4 module it wouldn’t pair and you would not be able to control the lock. You need to run a ZigBee configure on lock state to get reporting (and/or use a handler that reports Operating Mode).
I’ve written a DTH that offers more functionality, though it is limited with Kwikset locks. It can be found below. You’ll have to add your fingerprint and model as I only have the ones in the default handler. If that works for you I can add it permanently. The nice thing is that you can hit the force configure button to rerun ZigBee configure. I’ve also added health check that will automatically do that if after 2 hours you still have not gotten a response from the lock.
