For your lock you may want to check out this device handler particularly since your lock has many advanced features and also fixes a few issues with the stock one: [RELEASE] Universal Enhanced Z-Wave Lock Device Handler
For programming the lock check out Lock User Management (LUM) which is a very powerful and flexible app: [RELEASE] Lock User Management (LUM)
For your switches you’re better off using the stock device handlers since they don’t have any special features or settings which can be helped through a custom handler. The added advantage is that the stock switch device handler runs locally on the hub and is faster/more responsive. It can also work with local automations (in future) incase your Internet is out.
