FYI...
I have had a Schlage FE599 Z-Wave lever lock on my garage door for a few years now. The first one seemed to last about two years and Schlage replaced it under warranty. The current one started having issues responding to commands and reporting events. (I would have to take the internal metal cover/plate off for it to work reliably.) Ironically, it is right around the same two year mark. I called Schlage for troubleshooting. They felt it was a warranty issue and informed me that they no longer make or have any stock of the FE599. They did however offer a Dexter (made by Schlage) JFE 109 Z-Wave lever lock.
This Dexter (made by Schlage) JFE109 is a nice lever lock. It is not advertised or listed as a product on their site. You can only find FAQ material on it. The electronics (read Z-Wave radio antenna) are housed in the interior portion of the device, which is an upgrade from the FE599, which housed the electronics in the exterior portion of the unit. This has resulted in improved communications to my Z-Wave network, since my garage door is steel fire-rated (code). Batteries are also easier to change, since you don't have to disassemble the interior housing to get to them.
I am using the built-in Schlage FE599 driver with it and that works for all except one of its functions. There is a special function you can enable on the lock for override of auto-lock, which when interacted with, results in an "unknown" lock state. I think this driver cannot understand the lock state and/or alarm state of the lock. I seldom would care about that, so ignoring it. I also tried the Generic ZWave Lock driver and it seemed to work for the most part.
Since there are very few options left on the market for ZWave/Zigbee lever-only locks, I thought I would drop this note to let you all know there is an undocumented option that works fairly well.
