Locks are certainly at the complicated end of the ZWave device spectrum. They are part of a class of device known as a Barrier device.. They are built to keep the outside on the outside and the inside safe on the inside. Garage Door Openers are in the same Barrier Class.
Barrier Class devices MUST Join Securely. Must. If they don't Join securely, they are required to NOT Work.
On the Device Info page for the device, scroll down and look here:
Notice the "zwaveSecurePairingComplete: true " line. Required.
Hubitat has an option for limiting Secure Joins. Truthfully you really only want your barrier devices to run securely. There's overhead to a secure communications which translates to 'slower.' Noticeably slower, noticeably higher load on the Hub.
On to Joining... (join is the ZWave word, pair is the Zigbee word for the same thing... great huh? )
There's two components of the ZWave specification that is almost specifically for Locks (barrier devices)
- Whisper Join
- Beaming
Whisper was created to reduce the possibility that someone sitting out on the street could capture your Lock's security codes. They decided that dropping the transmit power way down was the method. This forces the distance between the lock and the hub DURING JOIN to be inches, not feet. It is an OPTIONAL component. Not every lock does this, especially newer ones.
Beaming is a mechanism to work WITH the battery of your locks. Most AC powered devices support Beaming, but if you have a concern, look up your device at the ZWave Alliance. All manufacturers MUST submit a Conformance Report and they are available to all of us. Beaming is always spelled out, yes or no. Beaming is also Optional.
Here's an example of a GE/Jasco wall socket/outlet. Beaming is supported.

A Beaming capable repeating device will assist the Hub by being the device that waits for the battery driven lock to wake up and hand off the hub's message.
Check your Lock at the ZWave Alliance, you probably see it supports beaming and therefore you will want to extend your lock's battery life by having a beamer within 8-10 ft. Like any repeater, it can be further away than the lock,
Secure Join
Whisper
Beaming
Those are the Keys to the Lock kingdom. I must suggest that the Locks be towards the end of your migration path. You want a good mesh and devices that have identified themselves to the Hub for beaming to get a simplified Join.
