Just an FYI to those that would still like to try swapping out modules...
I purchased this Kwikset Convert Smart Lock Conversion Kit on Amazon for $21.60. Took the Zigbee module out of it and swapped it into my 912 (formally zwave) lock. Works perfectly!
To recap, I have never in 6 years had a reliable connection to my bulkhead door lock. It worked perfectly near the hub (both Hubitat and before that, ST) but never worked on the door. With the zigbee module installed into the lock, it now works like a charm and cheaper than buying just the module on eBay!
There are plenty of these to be found on Amazon, just pick the cheapest used one available since it's only the zigbee module that's needed. Worst case, it doesn't fit/work with your lock and you just have to return it.
