I seem to remember that there is a way to manually force your device to use a driver that is not automatically assigned. I have done this in the past (with a thermostat device) but need to figure out how I did it and update this reply.
That said, a smart lock is a critical security device and an exact driver would be better/safer.
I need to find more precise steps, but the proposed solution is to use the developer.smartthings.com web page to select a driver that may not have the exact right fingerprint.
I presume you have paired your lock and it currently uses ‘Zigbee Thing’ driver?
