Schlage and Yale are generally very good quality locks with solid chipsets. We’ve used over 50 models over the last decade in all kinds of environments (rain, run, snow etc) and some have failed but many are still running.
Kwikset locks tend to experience zwave chipset failure after a few years leading to a battery drain, but some models allow you replace the zwave module so it could be a quick fix.
Schlage locks have modules which are soldered in but are very reliable in general. If they do fail customer support is quick to replace the lock. However some of these locks do have a firmware problem in their zwave module (which’s chal ge refuses to fix even in their newer zwave plus chipsets) which prevents them to working properly where there is mesh packet loss. They are also notorious for requiring repeaters to buffer packets as they are susceptible to mesh timing issues.
Yale lock by far have been the most stable and reliable locks. Some of the very early zwave modules had a battery issue but the newer zwave plus modules are rock solid and tend to have the best battery life as well as the best mesh connectivity leading to fewer problems than other brands. Also they have interchangeable modules so you can replace a zwave with a ZigBee or a WiFi module.
