Zigbee Kwikset 916 Smart Lock with Zigbee2MQTT joins and immediately disconnects

I have a Kwikset 916 Smart lock that I’m trying to pair with home assistant. I am able to pair it however it immediately disconnects.

Setup:

Here are the relevant logs. If I fiddle with the lock the smart lock successfully sends a command back to Zigbee2MQTT

Things I’ve already tried

  1. Using ZHA (And disconnecting and removing)
  2. Setting up Zigbee2MQTT and Mosquito
  3. Using a USB extender to remove interference
  4. Using fresh batteries
  5. Pressing the B button 9 times to reset the network settings
  6. Pressing and holding the program and reinserting the batteries and continuing to hold for 30s
  7. Calling Kwikset customer support but the tech wasn’t aware of home assistant really

Anything else for me to try?

Is it on this list?

Thanks for sharing this compatibility list, I did not know about it before.

Interesting, it is not on this list directly but this one is similar Kwikset 66492-001 control via MQTT | Zigbee2MQTT.

But it is on ZHA’s list so maybe I go back to trying ZHA. Kwikset SmartCode Traditional Electronic Deadbolt 916TRL ZB Zigbee compatibility
